Dear U-Boot support, I have problems while running following commands in U-Boot:

Here is how I create UBI partition in Linux env: Linux Env #> mtdinfo -a mtd5 Name: data Type: nor Eraseblock size: 262144 bytes, 256.0 KiB Amount of eraseblocks: 148 (38797312 bytes, 37.0 MiB) Minimum input/output unit size: 1 byte Sub-page size: 1 byte Character device major/minor: 90:10 Bad blocks are allowed: false Device is writable: true Linux Env #> ubiformat /dev/mtd5 ubiformat: mtd5 (nor), size 38797312 bytes (37.0 MiB), 148 eraseblocks of 262144 bytes (256.0 KiB), min.

Please help me identify the problem! Best regards, Denis Bakhvalov _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
