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,
Sajan

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
