* [U-Boot] UBI attach issues @ 2016-02-01 8:58 Andy Ng 2016-02-01 9:34 ` Heiko Schocher 0 siblings, 1 reply; 4+ messages in thread From: Andy Ng @ 2016-02-01 8:58 UTC (permalink / raw) To: u-boot 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.

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 -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany ^ permalink raw reply [flat|nested] 4+ messages in thread

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... bye, Heiko > > best regards, > Andy > > On Mon, Feb 1, 2016 at 9:34 AM, Heiko Schocher <hs@denx.de> wrote: >> Hello Andy, >> >> Am 01.02.2016 um 09:58 schrieb 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?
