MPC5743 CAN interrupt

xuan — Sat, 13 Apr 2024 02:42:17 GMT

HI,

I have a total of three CAN communications, CAN2 uses interrupt reception, I use the same configuration to receive interrupts to CAN0, CAN1. The program will get stuck in the receive interrupt, what is the cause of this, and what is the difference between CAN2 and other CAN receive interrupt configurations

Hi,

there is no difference in interrupt usage between CAN instances, except of different ISR vector numbers. What does "The program will get stuck in the receive interrupt" mean in fact. Does it mean interrupt is repeatedly called? If yes, be sure interrupt flag is properly cleared.
