Hi,


Thanks a lot for the info provided, let me test this on our side.


Also, could you provide the Quartus build version? You can find this in the "Help" tab in Quartus.

mailbox_simple doesnt compile either:

/projects/c5_nios/software/freertos_bsp/drivers/src/altera_avalon_mailbox_simple.c:36:10: fatal error: nios2.h: No such file or directory
   36 | #include "nios2.h"
      |          ^~~~~~~~~

This is FreeRTOS for NiosV Quartus Prime Lite 23.1 Build 991.
