- Subject: [ECOS] ARM gdb backtrace weirdness
Hi
Something is bugging me for a while so I thought I'd ask:
I have strange backtraces with arm-elf-gdb 5.2.1 (other versions too)
the sleeping threads' last frame is not in a function but in data space
Something to do with limitation of gdb or due to being called from unlock_inner?
I suspect a bug in the application of course since when run through gdb it does not work
but it works loaded form redboot.
delivery is a semaphore not a function...
Any ideas?
thanks.
