I am using RTX51_full,and I made a program with CAN controller(sja1000),now I have a trouble with can communiction.Except of CAN,all others seem well.When I add some code that independent of CAN operation,the CAN may cause fail,even when I change the Code Optimization level the CAN communication may get OK or fail.
Can someone give me advise
thank in advance

    thank you
    CAN hardware is working fine.The communication between cpu and CAN chip is also well,I can use can_send() and can_wait() to send and receive data,but the remote frame(D_SEND_R_REC) usually get wrong.Some time it may ok,but when I add some new code to the other task(no deal with CAN)or change the code Optimization ,the remote frame may not answer correcttly.At this time if I add some new code again,perhaps it may get ok now .Why?
    thank you very much!
