Android8 Filesystem not Mounted(To boot from the SD card)

[crl6crl6]

HI, All,

I'm using imx6q Android 8 BSP. Android not able to mount the system.img.

To boot from the SD card, perform the following operations:

crl6@crl6:~/android_build/out/target/product/sabresd_6dq$ pwd
/home/crl6/android_build/out/target/product/sabresd_6dq
crl6@crl6:~/android_build/out/target/product/sabresd_6dq$ cat /etc/issue
Ubuntu 16.04.3 LTS \n \l

crl6@crl6:~/android_build/out/target/product/sabresd_6dq$ sudo ../../../../device/fsl/common/tools/fsl-sdcard-partition.sh -f imx6q -c 14 /dev/sdb

the board log is at below:

re-reading partition table
GPT fdisk (gdisk) version 1.0.1

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.

Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! One or more CRCs don't match. You should repair the disk!

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged

****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
****************************************************************************

Command (? for help):
Recovery/transformation command (? for help): Warning! This will probably do weird things if you've converted an MBR to
GPT form and haven't yet saved the GPT! Proceed? (Y/N):
Recovery/transformation command (? for help): Warning! Secondary header is placed too early on the disk! Do you want to
correct this problem? (Y/N): Have moved second header and partition table to correct location.

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): OK; writing new GUID partition table (GPT) to /dev/sdb.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.
