Hi All, I am currently working developing M_CAN driver for MPC5777M, sometimes it is working fine , but some times it is unable to send  data as it is always showing the register TXBRP = 0x1and it is not becoming zero . currently I configured only one tx buffer for transmitting CAN messages,Even I configured two Txbuffers also it is saying TXBRP = 3(0x0011).
