[mrigendra_chaub]

Failed to make and chown /acct/uid_0: Read-only file system

I have a i.xm6q sabresd reference board and another is development board based on i.mx6

I am trying to port android O on development board and I have almost got it but I get so many of these errors,

I see these

init: Failed to make and chown /acct/uid_1040: Read-only file system

errors.

1. I don't know where to look for to solve and debug it.
2. I can do su and get root access, but why its not mounted as root?

[b36401]

It seems the filesystem needs checking and it is getting mounted read-only with the boot.
Please try to attach the card to Linux PC and perform fsck for all these filesystems.

Have a great day,
Victor
