Re: [Linphone-users] linphone crash when talking in BF548 board

[damico]

Hi,
First of all I don't think that is the right place for talking about
this issue. It looks like a Bfin's specific issue.
I can try to give you some tips:
1)"ADSP-BF548-0.2(Detected 0.1)" : fix to the right process revision
(0.1) while compiling kernel. I don't think it does really matter but it
is always better use a chip revision equal (at least less but never
greater) for compiling.
2)If you would like understand that trace take a look to
http://docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:analyzing_traces&s[]=stack

3)Ask to uclinux bfin guys ... maybe they can say to you the better
steps to understand the root cause of this issue.
Regards
