    Hello,

    Is the default WIC image booting correctly? The issue only comes with the WIC image you built?

    Thanks!

    Yes. 
    But I flashed  .wic image using balena etcher. It will help to boot.
    Can't find what the issue associated with bmap img flash. It will copy the files at a very high speed. Takes only 2 and a half minutes for create sd card. But can't boot up.

    Warm Regards,

    Hello,

    In that case, can you check the md5sum of the U-Boot images in both the cases. Ideally, they should be same. However, if they differ then we know there is some issue.

    Specifically,

    • Flash the SD card.
    • Unplug and plug it back.
    • Go to the mounted boot partition.
    • Check the md5sum of the U-Boot images.

    Repeat the steps for flashing via Balena Etcher and bmap.

    Regards,

    Prashant
