Tool/software:

Hey

I am working with MSPM0G3507 micro controller. I am using classic CAN.

I needed some help with CAN with external clock configured Can communicates at 500kbps. but when I power cycle it the CAN does not communicate.

I tried multiple times the CAN after power cycle does not communicate. I tried reducing the bit rate to 100 kbps it communicates after power cycling it as well

But my requirement is 500KBPS.Kindly please help me with that.

    Hi Muntaha,

    So when you first program the device it works, but after power cycling once it no longer works? Are you suing the debugger to step through the code on the first iteration but not after you power cycle? 

    I am wondering if you are running into an NMI or hard fault when you have the debugger disconnected. Are you using the __BKPT() command in your application code?
