morning

@jippie morning

@PlasmaHH Do you know of a tool that OS independently scans your C/C++ source and builds an include tree for each C file? Something is going wrong in a place that "nuttin' to do with me", but it is messing up my clean chain

@Asmyldof you mean like doc.ic.ac.uk/~dsl11/klee-doxygen/Solver_8cpp__incl.png ? that can be done with doxygen

not sure what you mean by "os independently"

if your code contains #ifdefs around #includes then you can set some predefined things that doxygen will evaluate ther

sometimes already looking at the preprocessed file (gcc -E, dunno about other compilers) gives some insight about something ^^

Hm, Doxygen setup is too much. I just want to see, preferably in a normal folder-tree-view kind how defines end up in a chain where they don't belong

Because there's some very strange branched-looping going on inside some upper layer

@Asmyldof nothing else that I know of, haven't had the need since I resort to these doxygen graphs if necessary. Don't think I ever saw anything that does it even tree view like

@PlasmaHH Shit my list of "have to make this" tooling is getting too big!

@Asmyldof mine got too big a long time ago

heh... someone is really confused

Anyone know someone who knows the uVision preprocessor? I'm fairly sure it's not expanding my macros before the conditional evaluation

wish I did

Download the trial, get to know it, change your mind about that exact statement and lead a happier life

What's its target? What is uVision for?

(before I actually spend the time to look for myself)

I found that a capacitor that I thought was 220µF, 250V, was in fact 220µF, 50V. Also found out that it starts breaking down at about 64V

Guessing it's electrolytic. Making it to 64V when it's rated for 50V is pretty good.

yup, glad that I had the current limit on

@W5VO I hope you didn't find it out in the clean lab.

@ThePhoton It was user error. No visible damage

Anybody know what's going on here? I have linux machine (Beaglebone black). My colleague says when its used with a static IP, if you remove the network cable and reconnect it, the network doesn't come back up. Anybody know what settings to look at?

@ThePhoton Not familiar with that phenomenon. Which Linux are you running? I'm not very impressed with the default what's-the-name-again distro that it comes with.

At least check if the interface comes up (ifconfig). Depending on the distro there is miitool or ethtool for extra information

ensure dhcpclient is not running, check what mechanism is used for ifup and ifdown.

I personally use Ubuntu on BBB, but it requires a memory card because of its size.

elinux.org/BeagleBoardUbuntu

@ThePhoton And the important question is, which OSI layer is your colleague referring to? Does the MII detect a link or does the interface not get assigned an (static) IP?

etc.

@jippie Currently defaults to Debian.

@jippie Honestly, I am not sure. We just changed "auto" to "allow-hotplug" in /etc/network/interfaces and stuff mostly works (except this issue). Hopefully this does not mean digging into a bunch of bash scripts attached to the hotplug mechanism.

@BrandenBoucher KEIL/ARM

@ThePhoton Afaik BBBebian uses the ifup and ifdown scripts, should be reasonably straightforward

But I've honestly mostly used the BBB for my own bare metal playgrounding

@Asmyldof I have a problem where if I learn something once and the forget it, I have a hard time getting motivated to learn it again. Linux hotplug and C++ are in this category.

@ThePhoton class JustOutOfReach{ private: void SolveAllYourProblems(void); protected: void FixYourBBBProblems(void); public: void IfOnlyYouTriedHarder(void); }

:-P

@Asmyldof I refuse to get that joke.

@ThePhoton Seems BBBebian uses ConMan for Ethernet.... @jippie You any idea?

Also ... teh stacks is full of people complaining about static IP in BBBebian

So....

This may not be your last issue

Be warned and all that

@ThePhoton type: "ps aux | grep conman" and/or "ps aux | grep wicd"

See if either is running

Seems, from what I read, that these are weird assist-applications that override the network file

Don't know if there's more silly programs like that

But, if your networks is impromptu or otherwise DHCP-less then not getting an IP at all would fit all the other symptoms people have with this program running your hotplug events

Gotta start cooking, or else I might even research deeper

Maybe we should ping @PlasmaHH in for some more un-embedded Lin insights into the plethoraness of these kinds of applications

@ThePhoton I'm cooking now, feel free to ping me for attention, it's not that difficult a dinner

@Asmyldof Looks like it was wicd. I can remove it, and then static IP will work; but DHCP breaks (goal is to get one disk image that can be used with minimal changes on either static or dhcp networks)

@ThePhoton Seems wicd also has some configuration

From your own link: "Editing /etc/wicd/wired-settings to include my static IP did the trick."

So make a folder with a bash script you make that you call like "setnw static" (if it's called setnw) which copies in a set of configs to the network and wicd folders

@Asmyldof Tried it and it didn't work for me. Somehow wicd ignored the edits to the config file, made me use its curses-ui to make the changes.

@ThePhoton :/

@ThePhoton there is a wicd-cli that you could try installing and making a script using that to reconfigure wicd

Or possibly remove it and see if that works....

Not a lot of USB connectors are rated for 2A, apparently.

@Asmyldof Removing wicd broke the ability to hotplug when configured for DHCP. But maybe there's another way to fix that.

@NickAlexeev Not many iPhones blowing up due to charging current either, though.

@Asmyldof Wicd is so well documented.

@ThePhoton 1.5A USB jack can probably tank 2A abuse.
