Subject: [U-Boot] Regression with ubifs initialization
Date: Mon, 27 Oct 2014 09:02:42 -0500 [thread overview]
Message-ID: <20141027140241.GA7726@og3k> (raw)
Hey all,
It appears that 2014.10 has some issues with UBIFS initialization
(details at bottom). git-bisect results in one of the following commits
being broken. Surely it is the mtd one, but its parent commit
(compat.h) does not compile.
[ff94bc40af3] mtd, ubi, ubifs: resync with Linux-3.14
[0c06db59836] lib, linux: move linux specific defines to linux/compat.h
A little background for the errors below. My MTD table:
device nor0 <0.flash>, # parts = 5
#: name size offset mask_flags
0: uboot 0x00080000 0x00000000 0
1: env 0x00020000 0x00080000 0
2: env_redund 0x00020000 0x000a0000 0
3: env_factory 0x00020000 0x000c0000 0
4: data 0x00400000 0x000e0000 0
=========================================================
Older (2014.07) U-Boot, I can do something like this:
$ erase nor0,4
Erase Flash Partition nor0,4, bank 0, 0x000e0000 - 0x004dffff

$ ubi part data
