Re: [ECOS] Build eCos and Handle/Interrupts problems

["Carlos Eduardo dos Reis Rodrigues Sobrinho" <epilog@netc.pt>]

BTW how can I do an application and store it in a certain address(for
example 0x4016969) in the flash so I do:
"go 0x4016969" or "gos 0x4016969" for instance and it copies all it has to
copy to SRAM and ran?

Thanks for the info in advance
Best regards Carlos Sobrinho

Sorry to being so anoying but could you or anyone give me and example of
using and interrupt to call a thread
Thanks

By memory layout do you mean "mlt_arm_aebC_rom.ldi" and "mlt_arm_aebC_rom.h"

Now I'm using cygwin 1.1.8
