AM625: MCU_MCAN does not work with HS-FS devices

Daisuke Maeda

Part Number: AM625

Our customer tested peripherals including MCU_MCAN on their custom boards. MCU_MCAN works on a board with a GP device, but does not work on a board with an HS-FS device. Other peripherals work on both of the boards.

MCU_MCAN is used by M4F core with MCU+ SDK 08.06.00.18. To migrate from GP to HS-FS, the initial boot image (tiboot3.bin) is changed from the GP image (tiboot3-am62x-gp-evm.bin) to the HS-FS image (tiboot3-am62x-hs-fs-evm.bin). An application image is unchanged.

Does the MCU+ SDK 08.06.00.18 support MCU_MCAN for HS-FS devices?

Could you tell me how to use MCU_MCAN with MCU+ SDK on an HS-FS device?

Additionally, our customer has an issue with MAIN_MCAN not working with PSDK Linux on an HS-FS device.

    Hello Daisuke,

    Yes, MCU+ SDK 08.06.00.18 supports MCU_MCAN for HS-FS devices.
    Could you tell us more about the error logs/whats not working here?

    Also, please let us know which example you are using for verification purpose?

    In order to test MCU_MCAN, generically you can connect to target, and with default configurations, run the mcan_loopback_polling/mcan_loopback_interrupt example.

    Regards,
    Aparna

    Hi Aparna-san,

    Thank you for your reply.

    Our customer has resolved this issue.

    They do not use PRUSS, so they disabled all definitions for PRUSS in the device tree on Linux.
    MCAN and USB that did not work now work fine but details are unknown.

    Best regards,

    Daisuke
