I manage to cope with these troubles, I send this e-mail to help anyone
who may have the same problems (I didn't find any documentation about
eCos on Integrator):
I'm working on an ARM Integrator Platform, my host is a Linux platform;
I have downloaded ecos_CVS directory on april 16th, and I have compiled
Reboot using (ecosconfig new integrator redboot; ecosconfig import
hal/integrator/.../redboot__ROM.ecm)
-arm-elf-gdb was falling down when I try to launch any program (cont
or step command) , generating a SIGBUS signal. Using "set debug remote
1" under arm-elf-gdb (T packet), I found that it was in
handle_exception_init routine. To end with, I understand that my program
and Redboot datas (bss section) were overlapping.
I cope with this by increasing _reserved space to 0x10000 in
mlt_arm_integrator_ram.h, mlt_arm_integrator_ram.ldi , and
mlt_arm_integrator_ram.mlt.
I had also an other problem with diag_printf function: arm-elf-gdb never
return from a diag_printf. Actually, the program was waiting for
debugger response.
Solution: serial line on Integrator should be plugged on Serial B
!!!!(serial A is OK for exchanging packet with debugger, loading program
and stepping, but diag_printf packets are only sent on serial B,
why???????? may be a wrong configuration of eCos kernel -where as
redboot configuration uses serial A and B- )
Regards,
Franck.
