Q: Embedded Linux Custom Boot Sequence

ddynI’m working on a custom boot sequence for my Arria 10 SoC Demo Board. Rbf files and U-Boot should be in QSPI Flash, and Linux Kernel and RootFS are in SDMMC. I have no idea how to reach MMC memory from U-Boot that is in QSPI Flash. I searched for an example with no luck. But since U-Boot can init...

 
slm
4:17 PM
@RuiFRibeiro done
 
@slm thanks.
 
Am new to these installation job on Redhat.. Basically from python development background..
I need to install these packages
gcc- gcc-c++-4.4.7-3.el6.x86_64
Flex - flex-2.5.35-8.el6.x86_64
Bison - bison-2.4.1-5.el6.x86_64
Glib - glib2-devel-2.22.5-7.el6.x86_64 & glibc-devel-2.12-1.107.el6_4.2.x86_64
Pcre - pcre-7.8-6.el6.x86_64 & pcre-devel-7.8-6.el6.x86_64

sendmail - sendmail-8.14.4-8.el6.x86_64 & sendmail-cf-8.14.4-8.el6.noarch
Do i need to configure some repo on redhat 7.4 server to use yum?
 
@overexchange I thought they were using a new package manager now.
 
I need something which is reliable and complete installation without headache...
I neverdid this before..
 
4:32 PM
But maybe they are still using yum on 7.4. Not sure how old that is.
@overexchange Just use the supported package manager.
A little googling should tell you what that is.
It's either yum or its successor.
 
# yum version

To use yum to install above packages... do I need to configure some repo? in the box
 
@overexchange Should be configured by default, what happens when you try to yum install gcc-c++-4.4.7-3.el6.x86_64 ?
 
so...seriously, if I'm used to Notepad++ or Vis Studio on windows, what is a good editor for CentOS? Either GUI or terminal based. Should I just learn vim?
 
@Jesse_b here is the output...
 
@JohnP I recommend continuing to use vs code

@JohnP vscode is happening in the market in both Linux & windows workd... If you used Vstudio in Windows before..
 
@overexchange Not sure. I haven't used redhat in years sorry
 
@Jesse_b how do I verify if repo is configured?
 
@overexchange yum repolist
but it looks like you have 6 repos configured based on your output above
 
Oh is it? haha
# yum repolist
Loaded plugins: package_upload, product-id, search-disabled-repos, subscription-manager

!rhel-7-server-extras-rpms/x86_64 Red
May be...
 
seems like they just don't contain the specific package you're looking for it
 
4:40 PM
I just got the box today.
If repo does not have this package..
Do I need to use rpm approach?
or add new repo?
 
If you know of a repo that has it you can add that or install from rpm/source
 
5:07 PM
@Tim Sorry it wont let me edit anymore but I have flagged for a moderator
 
Fast work. Hi guys.
 
I'm a mod on 3 other sites :)
 
Nothing to see.
 
@Jesse_b -Nothing to see here either.
 
@JohnP :(
 
5:19 PM
.
 
Dang what is this a CIA operation
 
@Jesse_b This is a user protecting his privacy. Perfectly reasonable.
 
@JohnP It was a github page not facebook or something
 
5:36 PM
@Jesse_b - not to belabor it, but you put in information that would allow a random person to discern the probably identity of someone that didn't wish that information to be here. Perfectly reasonable to remove.
You're in Denver? Fantastic! I grew up in a suburb, my family is all still there. Wish I was there. :(
 
@JohnP Personal information!
:-)
 
@Jesse_b The difference is, you brazenly flout it in your profile. :)
 
@JohnP Because I'm not a spy for the CIA :p
 
@Jesse_b So you say. Where's your proof?

Halp !
 
I think I've just become too old and jaded. My friends criticise me for using facebook messenger as my primary means of communication because "what about privacy?"
I find it cute when people think it's possible to have privacy on the internet
But I also wonder what the hell they talk about that they are worried about their messages being seen
 
@Jesse_b Internet is technically a public space. But it's possible to have certain degree of privacy.
 
@Jesse_b It's possible. But it needs work.
 
@SergiyKolodyazhnyy Sure, a certain degree, but if a three letter government agency wants dirt on you they will find it
 
5:48 PM
Avoiding Facebook and similar platforms helps.
@Jesse_b Not necessarily. Not if there is no dirt.
 
@FaheemMitha Everyone has dirt, but if you don't then why are you worried about privacy?
 
@Jesse_b And that's why the biggest question in infosec world is "What's your threat model and who is your adversary?"
 
@Jesse_b I don't think they were worried about alphabet agencies.
 
@Jesse_b There are reasons to be concerned about privacy other than dirt.
 
@FaheemMitha Such as ?
 
5:50 PM
Of course, the term "dirt" isn't well-defined.
@SergiyKolodyazhnyy Fraud, for example. Is that a serious question?
 
@SergiyKolodyazhnyy Well, he puts his full name and location in his profile. Just from that, I've got a pretty good idea of a couple places he has lived and some relatives.
 
@FaheemMitha Yes, serious question. Just wanna know what ideas other people can come up with
 
@SergiyKolodyazhnyy Fraud is a big problem. And the more people know about you, the easier for them it is.
 
@FaheemMitha I'm just old and jaded. I used to be very passionate about the government specifically staying out of my private affairs and never liked the saying "If you have nothing to hide you have nothing to worry about." Don't get me wrong I still believe that people shouldn't be meddling in my personal affairs but I pretty much don't care about it at all anymore. I know the government and corporations like facebook are out of control and I certainly wont be able to make them change.
But I don't have anything to hide so it doesn't really bother me
 
Another possibility is defending against criminal actions by the government.
Which through much of history, and in many places, is a major threat.
 
5:53 PM
@FaheemMitha Sure but do you really think facebook is using the data they gather from you to steal your identity?
 
@Jesse_b You don't have to give people information if you don't want to.
 
protection from fraud is different than what I'm saying I think
 
@Jesse_b No, of course not.
But they share their information with other entities.
Do you really know how far your information has gone?
 
They mostly collect information for analytics/advertising purposes
 
@Jesse_b And share it with others.
 
5:55 PM
Sharing information alone isn't the problem. It's the type of info and type of adversary
 
@FaheemMitha Yeah but basically every company does that now
Virtually every company sells all the phone numbers they have as a second form of income
Which again I don't agree with I have just given up caring. I'm going to get spam calls no matter what I do, I'll just hang up on them
Google is going to track all my searches, facebook is going to read all my messages, android is going to read all my texts
 
@SergiyKolodyazhnyy This. For whatever reason, say some whackadoo decides one of your repositories just ruined their life. Profile information can tell me where you are, your relatives, where you work, where you have lived, etc.
While it might be impossible to hide on the internet, that doesn't mean a random chat comment should make it easy. :)
 
@JohnP Well the issue from above wouldn't apply to this as that user had no profile information set :p but sure maybe one day they would
 
@Jesse_b There are defenses against all those things. Like I said, it takes some work.
With Facebook, just don't use it.
 
@Jesse_b No, but you linked to something that had more information, and from that I was able to find more information. Just because you don't mind people knowing you were in the Marines, or your last job, etc., doesn't mean there are people that want to be more private.
 
6:03 PM
@JohnP Where are you finding all this information about me? :p
 
@Jesse_b Simple google search. Led me to linked in, facebook, some of the "tracker" sites that give possible relatives, and the personal pics (mostly) match up, so I'd give it about an 80% certainty.
 
Btw, hi Denver folks :)
 
@JohnP Also I'm not really arguing that it should have been shared. I mostly agree and would have removed it myself if I could have. I just don't see it as that big of a deal as I shared something that the user has already made public in another forum. It would be a big deal if it were some private profile or information about that user posted by someone else
I just feel if there were some information that user didn't want shared they wouldn't have shared it in a very public place
 
@SergiyKolodyazhnyy It is a problem. Sharing information lets others get a more complete picture.
 
@Jesse_b Quite possibly, and I'm not arguing that you are wrong. However, they requested removal of it, and flagged it for mod attention. So...I removed it. I just did one step backwards, so had to get another mod to delete the history.
@Jesse_b Plus, there are a lot of people that don't want their SE accounts linked to their public profile, for various reasons. (Academia, Workplace spring to mind as two primary places for that).
@Jesse_b - Although I do have to give you credit, most of your FB profile is inaccessible, which is very often not the case. Kudos.
 
6:10 PM
@JohnP yeah I try to ensure it's mostly private
I would never get hired otherwise
I think I still have a very embarrassing myspace profile out there somewhere
 
@JohnP It's probably better not to have a FB profile at all.
 
@FaheemMitha well hurry up and make a facebook alternative and then get all my friends to use it
 
@Jesse_b Tell your friends to call or email you if they want to contact you.
And vice versa, of course.
 
@Jesse_b If it was titled after a breakfast food, then yeah, it's still there.
 
While phone and email isn't perfect, it isn't the NSA wet dream that FB is.
 
6:13 PM
That's me thinking about talking on the phone
 
And actually, I believe here are FB alternatives. It's just that nobody uses them.
 
@Jesse_b my wife too
 
@Jesse_b Seems like a bit of an overreaction.
 
@FaheemMitha Who said phone and email aren't ? Technically, there were cases of big companies like Verizon selling data. Oh, and considering phone circuitry is mostly digital nowadays, everything is traceable much easier than in 80s. There's even a question on skeptics site about it somewhere
 
@SergiyKolodyazhnyy this. Sprint has a portal for law enforcement agencies to log into and get whatever data they want. tmobile stopped nating phones so that they can be tracked more easily. All companies have standard procedures for "information requests" some charge a small fee others do it for free
 
6:18 PM
@SergiyKolodyazhnyy Well, email at least, is quite easily encrypted. And in theory, phone conversations can be too. Still, I take your point. But I still think FB is much nicer for people who trying to gather information.
Do US phone companies record everything then? Or are we just talking about who talked to who?
 
@FaheemMitha I don't think they record all conversations but they do store all text messages
As far as email, google gives the government free access to all emails on their servers
I'm sure the other big names do as well
 
@Jesse_b You can always use vkontakte and have the KGB reading your info instead of your gov.
 
Well, that goes back to the idea of "who are you and your adversary". I don't think encrypting an email to friend about how I spent last weekend is worthy of effort, and may not be worthy of reading for certain people. Different story if you're a political or business figure, and of interest to government or blackhats
 
@SergiyKolodyazhnyy My point is such systems could be easily automated if there was enough interest.
 
@RuiFRibeiro vkontakte used to be nice back in like 2007. It all went to hecky now. They actually blocked mine since like last year.
 
6:23 PM
@SergiyKolodyazhnyy Never used it....actually heard they were having probs with porn
 
@Jesse_b That's already better than FB then.
 
@RuiFRibeiro Well . . .they were . . . cough, cough
 
To be on the safe side, running non-Intel hw, and setting up local chat and video messaging might be better than using commercial services. That encrypting that stuff with private certs+a local VPN lol...and/or running it over Tor.
and even then. lol
 
Actually the larger problem would be copyrighted material. There used to be whole lot of movies you could watch there. Was awesome.
 
@SergiyKolodyazhnyy I think I used fb maybe 2 months ago last time.
@SergiyKolodyazhnyy I used to stream movies but almost all plataforms were taken down. A couple of them were russian.
@SergiyKolodyazhnyy I will got the netflix route. not worth the bother.
 
6:29 PM
@RuiFRibeiro If any of my friends tried to suggest something like this for communicating with them I would probably start to be very suspicious that they are a serious criminal.
 
@Jesse_b Nothing to hide mentality? .... Actually in the US you have a lot of "survalists" and similar activists.
I have not yet closed my fb account because of friends.
 
@RuiFRibeiro Not really. I wish we weren't being monitored as much as we are but I think the only reason to go through that much trouble to hide your activities is if you have something very heinous to hide
 
@Jesse_b There are people that go to that effort simply because they don't trust the gubmint.
 
@Jesse_b It is easy to setup such services. In the past I have a VPN connection to my home to a couple of friends, but just because they were being expats and their Internet was shitty.
Then cheap VPN services appeared...
I also used to run a Tor site, just for my use.
for getting around firewalls
 
@RuiFRibeiro I left Facebook for like 7 months mostly because I got tired of reading the dramma and sensationalist nonsense type of posts, and besides I had stuff in personal life that made Facebook kinda irrelevant for that time.
As for streaming stuff, well . . . . I watch YouTube mostly.
 
6:34 PM
@SergiyKolodyazhnyy I used fb with javascript filters, killing off all adverts, movies, pics and filtering words life football, obama, oprah, Trum, religion, feminism...no pacience for the common day-to-day trash.
 
@RuiFRibeiro Well, it's not hard for a tech person. Probably not for everyone.
 
@FaheemMitha Yeah.
 
I personally don't think it's hard at all. But everything is relative.
 
It went down from hundred of posts a day to may 3 or 4.
lol
 
@Jesse_b I disagree. For example, if you are a political activist, you need to be very careful.
 
6:36 PM
@FaheemMitha Or even gay in certain countries were it is punishable by death.
 
Obviously, I'm talking about the kind of activist that governments take a dim view of.
Working for freedom, justice, and all those dangerous, subversive concepts.
Ask Julian Assange and Edward Snowden. And all those whistleblowers.
 
I am no political activist, but once in a while I prefer using dnscrypt+VPN+tor...
 
@RuiFRibeiro Yes, for example.
 
It does not make me a criminal.
 
It's still technically illegal in India, for example. And India, by world standards is a relatively civilized sort of place. I stress the term "relative".
 
6:38 PM
I would also prefer having machines with no american tech.
 
@RuiFRibeiro Like no Intel CPUs?
 
@FaheemMitha yes....
RMS used for long time a yeellong
 
@Jesse_b It's a dangerous world out there. Remember that.
You happen to live in a country with some of the best protections in the world. But not everyone is fortunate enough to do so.
Civil and personal right protections, I mean, obviously.
 
@FaheemMitha All is relative.As an European I do see the USA as exactly the safest place.
 
@RuiFRibeiro Do or don't?
 
6:44 PM
do not
@FaheemMitha My country here is the safest place ever, people are too lazy and too stupid even to kill you. But then it has their own drawbacks.
 
@RuiFRibeiro Hmm.
I was talking about, for example, the Bill of Rights.
 
@FaheemMitha The bill of rights is not worth the paper it is written on nowadays.
 
@RuiFRibeiro I'd have to disagree with you there.
 
@FaheemMitha It is your pergorrative.
;)
@FaheemMitha StingRay....just for starters. Used at will by redneck police,.
 
@RuiFRibeiro I'm not sure what you mean.
 
6:50 PM
Google stingray....
 
@RuiFRibeiro I did. It's a fish.
 
@RuiFRibeiro Nasty.
 
@FaheemMitha They are being abused, there are report of police traking ex-gf and ex-wifes with it.
 
@RuiFRibeiro Of course.
 
@RuiFRibeiro Thank you. Very informative.
 
@Jesse_b One general concern people have is what will happen if their govt goes bad. For example, the US govt.
 
I mean, one could argue the US govt has never been good, but it's historically operated under some restraints. Imagine what a fascist US govt could do with data collection.
 
The same goes for any of the larger, more militaristic countries, at least.
I mean, for example, I doubt the Danish people lie awake at night worrying about what their govt is going to do to them. But lots of other people do. And we certainly worry about the govt here.
@RuiFRibeiro Wow, that's a lot of links.
@RuiFRibeiro What did you think of Citizen4? Good documentary, wasn't it?
@RuiFRibeiro I'm not sure what this one has to do with anything.
 
@FaheemMitha Citizen4 lot of smoke and mirrors. I do not like particularly holywood.
 
@RuiFRibeiro I think you are talking about something else. I'm talking about the documentary. It wasn't produced by Hollywood.
 
@FaheemMitha okok. highly speculative. I have seen it.
ĩ was aware of it.
 
@RuiFRibeiro Wow, that's detailed.
 
7:10 PM
@SergiyKolodyazhnyy Are there any Baikal based laptops by now?
 
@RuiFRibeiro No idea. I'm neither Russian not living in Russia to know :)
Nor I care about Russian laptops :)
 
@SergiyKolodyazhnyy I am particularly interested on non-western tech....if I can get hold of it.
 
Well, there's always Chinese and Japanese tech, but even then they use Intel CPUs or whatever.
 
@SergiyKolodyazhnyy There was for a while a chinese CPU. They got or were bribed with AMD stocks and went under...
Baikal is a cleam room implementation of ARM
DragonSon was a licensed clean room implementation of MIPS 64. Stallman used it on itś time.
I think DragonSon is only used internally by the Chinese now. Too valuable tech.
GodSon, sorry.
 
7:32 PM
Is that what you mean ?
 
@SergiyKolodyazhnyy yeah.
 
 
1 hour later…
8:39 PM
Debian turns 25....
 
@RuiFRibeiro When?
 
9:01 PM
Announced in August, first beta versions in December.
0.x versions, well.
@FaheemMitha Vaporware by August :)
 
@RuiFRibeiro So, a sort of 25 year anniversary.
 
yeah
@FaheemMitha I jumped ship from RH 6 to Debian in '96 when RH 7 messed up with the obj format or something like that.
 
@RuiFRibeiro A bit before my time.
That was before the ELF format, wasn't it?
 
@FaheemMitha yeah.
I actually had my first contacts with HP/UX around 1986....CRT terminals.
Then Xenix around 88
 
I got on board summer of 1998. It doesn't seem that long ago. With Red Hat, that is. I didn't start using Debian till 2001.
 
9:07 PM
or 89.
SCO V served me around 2 or 3 years around the 90s....
at home.
 
The only other Unix I'd use before that was SunOS/Solaris. But I didn't really learn anything till I got my own computer.
 
It happens
 
@RuiFRibeiro You've been doing it a long time. But I already knew that. I read your answer on that thread.
 
I also learned little with Ultrix in University.
Learned much more when later on had on my first job a farm of Ultrix machines just on my own.
Which were hacked on my first year....lots of opportunity to learn.
Fortunately, they were rather benevolent hackers too...only a script replacing the Oracle daemon and the shutdown binary....recovered anything from tape nevertheless...
then went on to another job to use AIX, HP/UX and Solaris...
and after that intenational projects using a RH variant already defunct, and Debian
international....
then managed an ISP and installed Debian on all their servers...and it has been Debian ever since, except in this new job were 99% of servers are either CentOS or RH.
@FaheemMitha I still have to install Xenix or SCO V on emulation lol
@FaheemMitha (Cut out from the story my stints as international network consultant and working as a network administrator)...My profile is a bit diverse.
 
I was only briefly a sysadmin. I didn't enjoy it much.
I felt very... underappreciated.
 
9:19 PM
@FaheemMitha It depends on the internal culture of the place too. Businesses not IT oriented are a tad bad places to work. When I work in ISP environments it is much more exciting and you have got a lot of similar oriented people around you.
@FaheemMitha Also senior admins are expected to take a lot of decisions on their own shoulders, especially when under fire.
 
@RuiFRibeiro I was at Duke University. Working for a guy who was kind of a creep. And who knew nothing about computers, and cared less.
 
It happens
 
I don't find working with computers the most exciting thing in the world, intellectually speaking. But it certainly could have been a more positive experience than it was.
 
@FaheemMitha There are jobs and jobs, projects and projects. (...) I have had very interesting projects
 
@RuiFRibeiro You should expand your answer.
 
9:24 PM
@FaheemMitha I am not inteding in turning their answer a substitute for my linked.in
who knows.
lol
I also got lucky I guess.
Right places, right time.
 
@RuiFRibeiro Well, I definitely didn't choose a good place or time to try to be a sysadmin. Though I did learn quite a lot, in hindsight.
 
@FaheemMitha I also left my previous job due to similar reasons, and my mistake was not leaving earlier...but I did got a lot of leeway there.
 
@RuiFRibeiro Also, being a foreigner in the US is not a great experience. It's not a friendly place for non-residents.
 
@FaheemMitha Got lucky I guess....worked two times in academia, and in 4 ISPs
 
@RuiFRibeiro Where in academia?
And did you like it?
 
9:28 PM
Porto and Lisbon.
Porto and Lisbon
was also an international consultant.
Academia? mixed feelings. Great for learning stuff and do investigation, collaborating with other universities...I helped our national universities with Radius....
but inernally too much back-sttabing and internal politics.
internally
 
When I was a sysadmin, I was working alone. Was never part of a team. Which doesn't help, I guess.
Psychologically, I mean.
 
@FaheemMitha I did my alliances, and created my customers. Had a lot of support from the dev team and the IT engeneering professors. But I had to got out of my way to create that.
 
@RuiFRibeiro Sounds like a lot of work. I'm never been much good at marketing.
 
@FaheemMitha Actually that I complained to the team lead.
"You do not do internal marketing of our work"
lol
 
@RuiFRibeiro I don't understand.
You mean he didn't but should have?
 
9:33 PM
@FaheemMitha If you do not do marketing of your work and people do not know you are doing...
 
@RuiFRibeiro Yes, quite.
 
then you might be doing the greatest job in the world and people say you are lazy.
The IT department was not very well seen
I gave a lot of support also to professors and especially devs, because at the end of the day, it was better knowing what they were doing, and planning in advance for that
than try to guess things and putting out fires
It also allowed me giving a guiding hand and things not getting so out of hand.
Then it also had benefits...when I setup open source VPN solutions, a professor voluntereed to do the beta testing and got me 300 hundred better testers that he managed.
beta testers
 
@RuiFRibeiro Yes, my experience was mostly people don't care.
@RuiFRibeiro You know you can edit the chat, right?
 
It is a lot of politics and internal alliances in academia. My first experience was bad, in the 2nd I knew how to play the game.
I know.
@FaheemMitha Going to bed. Take care.
 
@RuiFRibeiro You too.
 
9:46 PM
Wifey already fast asleep, was going there to keep her company. I keep later hours.
@FaheemMitha wont be on chat for long anyway.
My advice: market well your work. A bad boss will have much less chance of screwing you over.
A real nasty and ill-intentioned boss also knows how to do negative marketing of your work. I have seen it all.
 
@RuiFRibeiro Sounds like good advice.
 
@FaheemMitha Unfortunately learned it the hard way.
 
Though that sysadmin work I was mentioning wasn't a regular job anyway. It was sort of something I fell into. I was just trying to help out. Bad move on my part.
In this world, you need to look out for yourself, and watch your back. Because nobody else is going to do it for you.
 
@FaheemMitha I was asked to pick up in university the Linux department cause I give a big helping hand to the network and dev team...then politics went on the middle and I was never formelly appointed as team lead. Too long a story.
 
@RuiFRibeiro Were you still a student then?

In my last gig...no.
In my first gig, I was hired directly for Unix administration.
