TMS320F28377D: SYSBIOS HWI and CAN Interrupts

wang wang

Part Number: TMS320F28377D

CANIntEnable(CANB_BASE, CAN_INT_MASTER | CAN_INT_ERROR | CAN_INT_STATUS); CANGlobalIntEnable(CANB_BASE, CAN_GLB_INT_CANINT0);When the above code is used to enable CAN interrupt, the DSP code stops running.How can I solve the above problem？

Can you explain in a bit more detail about you mean by "stops running"? Is it hanging somewhere? Is it generating an error message? If you put breakpoints in the code, can you determine a certain point at which it stops working?

ui32Status = HWREG(ui32Base + CAN_O_ES);When CAN triggers a send or receive interrupt, it is found that ui32Status is equal to 0xc08. Afterwards, CAN communication stops sending data.Thank you very much.

I have solved this problem. If using the sys/bios system, the interrupt function should be written as "void canISR(void)" instead of "__interrupt void canISR(void)".
