[U-Boot] UBI attach issues

[U-Boot] UBI attach issues

[Andy Ng]

Dear u-boot team,

Occasionally, I get corrupted rootfs if the system power goes away
while u-boot is attaching the root file system in order to fetch the
kernel.

I am using imx6 Solo and u-boot 2013-10.

Is there any way to stop uboot messing up the file system while making
attachment of UBI? Does the latest u-boot provides a better way to
protect the ubi file system during attachment.


Any advice or guidance will be very much appreciated.

Andy

In principle U-Boot has the same code as Linux. Current
U-Boot uses Linux code from:

linux v4.2 commit 64291f7db5bd8150a74ad2036f1037e6a0428df2

see U-Boot commit: 0195a7bb36a0abc71145da419001377bf56662fd

2013-10 uses an older Source Base, so update to current U-Boot
is recommended... yes.

Do you see this issue also with Linux?

Do you use UBI FASTMAP?

bye,
Heiko

Thank you for your reply.

by going to update u-boot, does it guaranty corruption free UBI if the
power goes away during the phase where u-boot fetches uImage from the
ubifs?

best regards,
Andy

I cannot guarantee this. The problem can be also in the underlying nand
driver. Try current code, also enable UBI debug messages, may this
shows the problem...
