iMX8M plus : Androind 11 userdata partition is reformated always after SD card is flashed

[swapnilpendhare]

It seems the userdata is not accepted by the Android OS and it's formatted on first boot with SD card. I could see some security and partition signature related errors in bootloader, but could not find the root cause. 

I have attached the Boot log file.

• If you check like 55 to 65 of the boot log; You will see some issue in the bootloader with partition table magic numbers and it tries to reset metadata. 

Hit any key to stop autoboot:  0

In boota get fastboot lock status error. Set lock status

Magic is incorrect.

Error validating A/B metadata from disk. Resetting and writing new A/B metadata to disk.

Writing A/B metadata to disk.

 verify OK, boot 'boot_a'

Kernel load addr 0x40480000 size 52437 KiB

kernel   @ 40480000 (55246848)

ramdisk  @ 44680000 (12502925)

fdt      @ 43ab0400 (62921)

Moving Image from 0x40480000 to 0x40600000, end=43ab0000

• Also when the kernel is booted, if you check the logs between line 2069 and 2228 the userdata partition is formatted as it was considered corrupted earlier.

We are currently using ./imx-sdcard-partition.sh provided in imx android build along with all the android images when I build android. Also sharing SD card creating log.
