Hi everyone, I'm trying to implement FreeRTOS on a NIOS II processor by using external controller (Vectored Interrupt Controller), but I get some errors when compiling. FreeRTOS call some functions that are related to the internal interrupt controller like altirqhandler and so on. Does FreeRTOS support the VIC on NIOS II processor? Thank you very much. Best Regards, Michele

The NIOS port C file is quite thin, with a lot of the port implementation being int he asm file. Assuming the asm file does not make the same assumptions then I think the C file can be adapted to use an external interrupt controller with minimal changes. Perhaps make prvSetupTimerInterrupt() a weak function (attribute((weak)) qualifier added to the function's prototype) then re-implement the function in the application code. Likewise the interrupt handler.

Some functions changes like irq_enable too. So finally we have to write the interrupt handler by ourself. Thank you.
