The U-boot has to load the kernel and initramfs from a UBIFS partition. > Recently we made an upgrade from U-Boot version V2010.12 to version V2014.10. Now after some regression tests with power cuts, we got an UBIFS state, which is unreadable for U-Boot version V2014.10. If I do a tftpboot an mount the UBIFS with linux, there is no problem. It is also very strange, that if I downgrade the U-Boot to V2010.12, then it is also no problem with the partition and everything is readable. I tend to say there is probably a regression with the most recent U-Boot version. But I don't know where I can start to find it. I enabled also the DEBUG define, but there appears no additional debug message concerning UBIFS. How can I debug this? You can enable: #undef CONFIG_UBI_SILENCE_MSG #define CONFIG_MTD_DEBUG #define CONFIG_MTD_DEBUG_VERBOSE 1 With which Linux version do you test? U-Boot is synced with linux 3.15 ... so, if you can test it with a kernel >= 3.15 this would be great! > Here the output from U-Boot V2014.10: > > => ubi part fs > UBI: attaching mtd1 to ubi0 > UBI: scanning is finished > UBI: attached mtd1 (name "mtd=0", size 63 MiB) to ubi0 > UBI: PEB size: 131072 bytes (128 KiB), LEB size: 130944 bytes > UBI: min./max.
