AM6421: receive all error frames after modifying disable loopback in example project

Part Number: AM6421

Tool/software:

Hi there,

When using MCAN0 on the R5FSS0-0 core with the original example project (with loopback enabled), it runs normally.

However, after modifying to disable loopback, all received frames are error frames.

My local modifications are as follows:

- Disabled loopback.

- Commented out RX-related code.

- Set both nominal and data bit rates to 250 Kbps (the same value).

The error frame details are as follows:

My local environment information:

- Original example file path:

C:\ti\mcu_plus_sdk_am64x_10_00_00_20\examples\drivers\mcan\mcan_loopback_polling\am64x-sk\r5fss0-0_nortos

- CCS version:

- MCAN module:

MCAN0

- Running core:

AM6421 R5FSS0-0

Please troubleshoot the issue based on the above information

and provide the correct Init/De-Init sequence for the CAN driver.

Regards

Jaxon
