Tested it on my custom AM335x board. Haven't used mainline U-Boot but cherry-picked the following commits: linux, compat: add missing definitions for ubi ubi/ubifs: some bugfixes ubi,ubifs: sync with linux v4.2 ubi: reset mtd_devs when ubi part fail Commits apply cleanly except for "linux, compat: add missing definitions for ubi" which was trivial to backport anyway. U-Boot built fine, but there was a warning: drivers/mtd/ubi/fastmap.c: In function 'ubi_attach_fastmap': drivers/mtd/ubi/fastmap.c:816:2: warning: pointer targets in passing argument 3 of 'scan_pool' differ in signedness [-Wpointer-sign] ret = scan_pool(ubi, ai, fmpl->pebs, pool_size, &max_sqnum, &free); Just sent this patch which should fix it: http://patchwork.ozlabs.org/patch/531842/ The board seems to work fine, and I can even to "nand erase" and "ubi part" without any problem. However, I'm still seeing the same warning I had before, when my partition is attached: ubi0: default fastmap pool size: 200 ubi0: default fastmap WL pool size: 100 ubi0: attaching mtd1 WARNING in drivers/mtd/ubi/fastmap.c line 846 ubi0: scanning is finished ubi0: attached mtd1 (name "mtd=7", size 509 MiB) ubi0: PEB size: 131072 bytes (128 KiB), LEB size: 129024 bytes ubi0: min./max.

Do you know which of the fixes should fix that? -- Ezequiel García, VanguardiaSur www.vanguardiasur.com.ar _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
