How are kernel size reports generated?

Hello! I'm very curious how are the kernel size reports (available here - http://chibios.sourceforge.net/reports/kernel.txt ) generated? I looked in the source tree for any script that generates that info, but I failed to find anything related. Maybe the number is just the size of .text + .data for ...

Re: STM32f429 Demo - Suspend not possible

Try the most recent release - 131228. I think I've stumbled upon the same problem as you with the previous versions (from August, October and the one from 2 days ago), but in the new version the problem is solved - at least here (;

Re: [FYI] Licensing News

Just imagine how many people break BSD license, by NOT including any info about lib in documentation which accompanies the binary (; With Boost license you just stop the hypocrisy (;

Guys, have a look the the page http://gittup.org/tup/make_vs_tup.html The guy is funny and knows about the drinking thing..;-) The website is really funny indeed (; Freddie, did you ever apply tup on a ChibiOS build? I'd like to try that, but don't wanna write the...

Re: Compiling duration

You're searching in the wrong direction. If you're using make from MSYS than there's no surprise it's slow - recently they decided that make on Windows should be case insensitive (or sth like that), so if you have rule for your_file.c then this make will check whether it did not actually match: your...

Re: [RFC] Ideas for ChibiOS/RT 3.0

1ppm = 1/10000 %, but for this case it's just easier to calculate with 1 point per milion, so for 30ppm resonator after 1s the result can (but doesn't have to) be off by 30us. I can't imagine how you got to a number that says a precise clock crystal resonator has an error of 3%...

Re: [RFC] Ideas for ChibiOS/RT 3.0

It's not a matter of "problem", as you can as well use assembly instead of C/C++ and RTOSes, but a matter of code re-use. There are MILIONS line of code available to PC platforms and that can be reused, but you need a proper and functioning abstraction to deal with that. And that "pro...

That leaves the actual paths to the devices...
