I’m receiving a NMI exception now that I’ve added a second HWI on a custom C6748 board. The program operated properly using an EMIFA interrupt (selection 55) tied HWI_INT4 using the dispatcher with an “all” Interrupt mask (I’m also clearing the interrupt after receipt). I’ve now added a second interrupt (HWI_INT5) tied to the UART Rx interrupt (selection 38) with the dispatcher. The UART read happens first and processes fine and once complete the EMIFA interrupts start and on the second interrupt the NMI exception occurs. When I don’t input anything on the UART Rx the problem does not occur. I’ve examined the NTSR register is per another posting (reads 0x0001020F - INT, XEN, GEE, SGE and GIE all 1). Any suggestions on how to debug this issue?
Thanks, Dave
