Hi,

The log is pretty clear, there is a problem mounting the /cache and /data partitions:

fs_mgr: __mount(source=/dev/block/mmcblk2p4,target=/data,type=ext4)=-1

fs_mgr: fs_mgr_mount_all(): possibly an encryptable blkdev /dev/block/mmcblk2p4 for mount /data type ext4 )

fs_mgr: __mount(source=/dev/block/mmcblk2p6,target=/cache,type=ext4)=-1

fs_mgr: Failed to mount an un-encryptable or wiped partition on/dev/block/mmcblk2p6 at /cache options: nomblk_io_submit error: Read-only file system

As it fails, the init process can't go any further. Please check how the SDCard/eMMC is partitioned.

Regards,

Gary

Thanks for your reply

I fixed partition error, I could run android OS on my custom board but sometimes it's still stuck on splash screen and auto reboot many times.

Hi Dang Nguyen Viet,

i'm porting Marshmallow to my custom board (based on IMX Sabresd) and i'm also stuck at splash screen, only shows "android", and the debug report is the same yours:

fs_mgr: __mount(source=/dev/block/mmcblk0p5,target=/system,type=ext4)=-1
fs_mgr: Failed to mount an un-encryptable or wiped partition on/dev/block/mmcblk0p5 at /system options: barrier=1 error: No such file or directory

Can you tell me how to fix this issue as you solved it before?

Thank you!

Hi,

Your partition/flashing is still wrong, same issue as before except that now it is because or partition 7 instead of 6. Please read the log, it is written there.

Gary

Hi Gary,

i configured partition in \myandroid\device\fsl\sabresd_6dq\fstab.freescale file as attached file and the same config in ucl2.xml file.

Can you see them and give me any suggestion please.
