AM2634: MCAN not working correctly in SBL

Part Number: AM2634

Hi

I'm working on a custom SBL with CAN support, but the MCRC module does not behave correctly in the SBL. TX messages are sent multiple times and RX messages sometimes are lost.

There are already several threads about this topic. However, I found nowhere a solution.

For demonstration, I integrated "mcan_loopback_polling_am263x-lp_r5fss0-0_nortos_ti-arm-clang" into the QSPI SBL.

The result on the CAN-Bus look like this:

Some ID's are sent four times and the example does not finish. In a normal application environment it is working.

I add the source code of the demonstration project:

SBL_CAN_Demo.zip

Can someone please help? Thanks.

Best regards

Dominik
