- Subject: [ECOS] data abort exception (SWI)
Hi,
I try to make a ecos project without Redboot for an atmel AT91M55800A (phycore). So it's a RAM project. I compile and debug an application without any problems.
When i try to generate a SWI (with asm("swi")), the application reach the exeption handler that I define but the number of the exception is not CYGNUM_HAL_VECTOR_SOFTWARE_INTERRUPT (number 2 that i give on cyg_exception_set_handler) but CYGNUM_HAL_VECTOR_ABORT_PREFETCH (number 3) . Maybe I might modify vector.S to do the remap (like hal_platform_setup.h ). If anybody have an idea? I search on your mailing and nothing fit well.
Best regards,
JJP
