CAN Debug problem

yiguangtang — Thu, 13 Apr 2023 06:15:55 GMT

One of the problems I encountered during debugging was to select filter mode A and call the FlexCAN_Ip_ConfigRxFifo function.

0x00F00000 is set in the incoming configuration table, extending frame. Extended frames can be received normally, but standard frames can also be received.

If isExtendedFrame is true, it can receive extended frames of 0x00F00000 and standard frames of 0x3C. If isExtendedFrame is false, set 0x00F00000 and no data will come in

Hi,

after RXFIFO table is configured, check content of MCR, CTRL2, RXIMRx registers and ID table area. Is there all as expected?
Do you have properly set RXIMR register to have bit30 set so IDE bit is compared?

BR, Petr
