Hi,

I am trying to launch "Gateway Demos" and the MCU logs only show

============================================================>

Gateway App:Variant - Pre Compile being used !!!
Gateway App: CanApp_Startup
CAN_APP: Successfully Enabled CAN Transceiver MCU MCAN0!!!
CAN_APP: Successfully Enabled CAN Transceiver MCU MCAN1!!!
GatePort 1 Address: 50:51:a9:Gateway App: Starting CAN Rx Interface
Gateway App: Starting CAN Rx Interface

<============================================================

I don not see any of the EthTrcv messages and the test result of CAN to ethernet is failed.

In the documents of "4.1.2 CAN to ethernet Gateway demo",

I should see the logs as below:

Is there any suggestion to check the problem?

Thanks.

    Hi,

    If I using CCS to launch "Gateway Demos", the function will work great.

    However the MCU will active ethernet failed while booting up from SD card.

    I may misunderstand the words:

    "Copy the CAN/Eth gateway demo application to the /boot folder in SD Card and rename it to app."

    If I copy the can_eth_gateway_app_mcu1_0_release.xer5f to /boot/app, then nothing happens on MCU domain.

    When I copy can_eth_gateway_app_mcu1_0_release.xer5f to /lib/firmware/j7-mcu-r5f0_0-fw, the ethernt will be enabled failed.

    Is there any suggestion about how to run the "Gateway Demos" from SD card?

    Thanks.

    Hi Sandro,

    The SD card binary is different from the CCS binary. It has the extension "appimage", so you need to copy the file can_eth_gateway_app_mcu1_0_release.appimage to the SD card /boot folder and rename it to app. Please try it and let us know.

    I reviewed the documentation and I see that it's not very clear from the steps. We will fix it in future.

    Regards

    Hi Vineet,

    It doesn't work whether I copy can_eth_gateway_app_mcu1_0_release.appimage to the SD card /boot/app or /rootfs/boot/app.

    Thanks.

    Hi Sandro,

    Sorry for the late reply. I didn't get an email notification for some technical reasons. Are you still facing the issue ? Can you confirm if 

    1. The SD card is bootable ? i.e. there are boot and rootfs partitions ?

    2. Are you able to boot any other PDK example ?

    3. Do you have the required boot loader and system firmware in the SD card ?

    Also, can you post the UART log of second MCU UART instance ?

    Regards

    Vineet
