that looks like a broken SD card to me … do you have a fresh one you could try with ?

After this error logs I had flashed yocto image through the same SD card and on the same board but the board was booting up.

well, perhaps your kernel is missing options for the controller or ext4 attributes then … though the above read error really looks more like hardware (could also be a power issue btw …)

have you logged in yet and checked the journal ?
