    @Darrin, thanks for the tip. It is possible that it might be a noise issue and its getting more pronounced at high speeds. I've already tried to increase the tolerance of network but that does not seem to solve the issue. I'll mitigating network noise in connection and see if that helps. ...

    Hi Zerong, If you are testing the loopback mode then you have to do both (candump and cansend) in the same console. Or you can do ssh and use both consoles for send & receive $ candump can0 & $ cansend can0 -i 9 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 Regards AnilKumar
