2011-09-23 18:55:17     help in debugging application crash

Tihomir Culjaga (CROATIA)

Message: 103519   

Hello,

we have built an application that connects to asterisk manager interface and collects events generated. According to some events, we are able to analyze calls and do all sort of things.... mainly realtime billing.

well, while everytihng works as a charm on an x86 machine... but here on blackfin we have a lot of issues. Crosscompile went fine, didn't have any issues. All i had to do was to build libhttpd, libsqlite3 and link it to my main application. All went fine and i can run the application on blackfin.

I'm running it on an IP04 board with ADSP-BF533 processor.

root:/etc>

I'm able to run the application, and asterisk on the stamp, but it is not stable at all... after some time either asterisk or my application crashes without leaving much info. I went through the code several times, tried to debug it but never got a real reason why i get these crashes.

I could write a lot of other information here right now, but i might just overload everyone with maybe not needed info...

please, can anyone help debugging this ?

Where do i start?

what do i need to look into ?

what information do you need in order to be able to help?

this is my dmesg ..and after a while i get a lot of errors like that.

  docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:analyzing_traces, check if this will help in your debug. Also the uClinux has something diffrent for application development comparing to the general Linux on X86, mainly about the meomery usage, like you are supposed to use vfork instead of fork. consult   docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:difference_from_linux&s[]=nommu for details.

Message: 103529   

Which binary format do you build your application into? FLAT or FDPIC?

If it is FLAT, could you please try to enlarge the statck of your application? The default stack in FLAT binary is only 4k bytes. Stack overflow may result in undefined instruction.

And don't defined large size local variables. Define it as global static or malloc it at run time instead.

Message: 103576   

it is supposed to be FDPIC as im using bfin-linux-uclibc-gcc

this is how i build my application:

./configure --host=bfin-linux-uclibc --disable-largefile  CFLAGS="-g -mfdpic -mfast-fp -ffast-math -D__FIXED_PT__ -D__BLACKFIN__ -fno-jump-tables" LDFLAGS="-mfdpic -ldl "
