- Subject: [ECOS] Problem with interrupts using ecos flash api
Hi,
I am facing problems in handling interrupts using the FLASH API of
ecos. My platform is GP4020 and I am trying to run opensource gpl-gps
code on it. When I load the code onto RAM using redboot it works fine,
but when the same code is executed from flash the program hangs once
the ?cyg_interrupt_attach() is called. I tried mapping the ISR onto
RAM and changing the interrupt vector where the flash address of the
ISR was originally written to the newly mapped one, but didnt work. Am
I proceeding in the right direction . Is there some problem with
interrupts executing from the flash and what else do I need to do to
get it working.
the code runs well from flash if the interrupt is not attached.
Can anyone please help me out in this.
Regards,
