MSPM0G3507: Can not communicating after power cycling

Hi Muntaha,

Are you debugging the device when this happens? Are you able to see some error in the CAN module or status register? 

What does the traffic on the CAN bus look like? Is this the only device on the bus and you are probing, or is there continuous traffic while the device is power cycled? 

Hi

After power cycling it does not communicate. I am debugging but it's not pointing to any error in CAN module. The bus shows heavy after power cycling. I have used the controller for two days and i dint face this issue.(ensuring nothing changed in hardware as well as software).

Sorry bus status shows OK, but the messages are not receiving..

Two messages i am sending...when i check those two messages before power cycling ...those two messages come

But after power cycling those two messages does not come..(Bus status shows OK)

Did the issue only come after updating something in your toolchain (the SDK or Sysconfig)? Could you inform me which versions of Sysconfig, CCS, and the SDK you are using to see this behavior? Which CAN Transceiver are you using? Is this using a launchpad or custom hardware? I will need this information in order to replicate the issue.
