The frame error is generated frequently when I use S32K142 CAN0. I configure the CAN0 & clock by PE in the attachment(figure 1 & 2).
BTW, the additional configuration as follows:
1. GPIO: PE5 - TX; PE4 - RX;
2. Mailbox for reception: Only use RX FIFO for reception: MB0 ~ MB7 is used;
Mailbox for transmission: MB8 for the broadcasting message; MB9 for other messages(not used yet)
The frame error always occurs in the ACK field(reception) & EOF field(both reception & transmission). please check it in the attachment(figure 3 & 4).
So what's the root cause? Is there something wrong with the peripherals configuration?
Thanks a lot!
