MSPM0G3507: MCAN RX/TX after breakpoint

Adam Lancaster

Part Number: MSPM0G3507

In the MCAN examples for this board all the READMES have the following note

Note: There is a known limitation where the example might stop transmitting/receiving

packages if the application halts execution after hitting a breakpoint. It is

highly recommended to use the free run option while testing the example.

Is there any workaround or planned fix for this? We need CAN to function properly when debugging.

Sorry, I need to consult my colleague, I will return back tomorrow after I get the answer.

Hello Eason, did you get any answer on this?

My colleague tested the MCAN examples and they seem to be working correctly when the the example reaches a break point and resumes operation. It seem that the note is no longer valid and it only affected the evaluation MSPM0. We will remove this comment from the examples in the furture.

Can you give more information as to how this only affected the evaluation boards? We are using an M0G3507SPMR on a custom board, and are experiencing this exact issue. Everything functions perfectly up until a breakpoint is hit, after which CAN fails to receive/transmit correctly.

Here is the feedback from our software team. Can you take a picture of your device?

If it is possible, can you share a smallest code example which can recreate this problem.
