PROCESSOR-SDK-AM64X: External CAN

Elbon ba

Part Number: PROCESSOR-SDK-AM64X
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi,

I’m running the example of internal loopback CAN for the AM64x board, but I want to translate this example to external CAN, using MCAN0 and MCAN1 on my board. I will connect the MCAN_H of MCAN0 to the MCAN_H of MCAN1, and the MCAN_L of MCAN0 to the MCAN_L of MCAN1.

However, I would like to know how to achieve this. How should I change the configuration? Are there any modifications needed in SysConfig?

Hi Elbon,

The example for external loopback is already available in the MCU+SDK, we are discussing on the same on this thread: (+) PROCESSOR-SDK-AM64X: I have a prob to run the mcan_external_loopback_interrupt_am64x-evm MCU+SDK example - Processors forum - Processors - TI E2E support forums

The default example works as expected, I suppose you are facing some issues after modifying the code, I am looking into the same and will update once I find something. Could you please continue the further discussion on the previous thread.

Thanks,

Meet.

Hi Elbon,

I have responded here for this issue: (+) PROCESSOR-SDK-AM64X: Issue in the mcan_external_loopback_interrupt_am64x-evm_r5fss0-0_freertos_ti-arm-clang example - Processors forum - Processors - TI E2E support forums

I request you to keep the discussion for a particular issue to a single thread, this will help avoid any confusions in the future.

Thanks and Regards,

Meet.

Hi Meet,

Regarding the change in sysconfig from LLD to HLD, I want to create my own code to test my CAN driver for sending and receiving data using mcan0 and mcan1. This has no relation to the example provided by TI. As you can see, the example is external, but when I switch to HLD, I notice that the configuration is set as internal loopback.

Do you have any insights on this?

Yes, as I mentioned the example was made using LLD infra, so there was no setting previously done for HLD, so once you change the infra to HLD it shows the default configuration (which is internal loopback mode).

Best regards,

Meet.
