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...
