    Hi Zhong,

    • Can you ensure that the switch settings that you have set on the board are as below:

    • Can you try the following command and check if the logs are coming:
    >sudo apt-get install minicom
>sudo minicom -D /dev/ttyUSB2

    I have downloaded the SDK from this link: PROCESSOR-SDK-LINUX-SK-TDA4VM Software development kit (SDK) | TI.com

    The file is tisdk-edgeai-image-j721e-evm.wic

    I follow the tutorial using Balena Etcher wrote the file into the SD card, I have formatted the SD card as FET32 before I use it.

    Thank you!

    Hi Zhong,

    Actually BALENA ETCHER seems to have issues usually.

    Can you try the following steps for flashing into SD card:

    Step1:

    Run the following script using the following command to partition the SD CARD:

    >sudo ./mksdboot.sh --device /dev/mmcblk1

    https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/2766.mksdboot.sh

    Step 2:

    Download the ti-processor-sdk-linux-edgeai-j721e-evm-10_01_00_04-Linux-x86-Install.bin  from the download link which you mentioned.

    Step 3:

    Copy the following files from the <ti-processor-sdk-linux-edgeai-j721e-evm-10_01_00_04/board-support/prebuilt-images> directory to the FAT32 partition of SD CARD.

    • tiboot3.bin
    • tispl.bin
    • u-boot.img
    • uEnv.txt

    After copying execute the sync command so that the cache is flushed.

    Step 4:

    Untar and copy the rootfs from the file with the name <edgeai> present in <ti-processor-sdk-linux-edgeai-j721e-evm-10_01_00_04/filesystem> directory to the EXT4 partition of SD card.

    After copying execute the sync command so that the cache is flushed.

    Step 5:

    Boot using sd card

    Hi Zhong,

    Sorry,I actually forgot to tell that you will also have to copy sysfw.itb from <ti-processor-sdk-linux-edgeai-j721e-evm-10_01_00_04/board-support/prebuilt-images> directory to the FAT32 partition of SD CARD.

    Also can you help us with the screenshot of lsblk command as well as the files inside the FAT32 partition of SD card.

    If possible can you also provide the md5sum of tiboot3.bin,sysfw.itb and tispl.bin,u-boot.img so that we can verify it on our end as well.

    Regards
