Hi!
I'm trying to use ubi.fm_autoconvert=1 with the current (v4.9-rc6) mainline kernel.
I have the following setup:
- kernel commandline:
(...) root=ubi0:root ubi.mtd=nand0.root1 ubi.mtd=nand0.data rootfstype=ubifs rw ubi.fm_autoconvert=1
mtdparts=gpmi-nand:(...),6M(nand0.kernel1),6M(nand0.kernel2),68M(nand0.root1),68M(nand0.root2),-(nand0.data)
- root1 partition: (is not empty when flashed)
mtdinfo /dev/mtd6
mtd6
Name: nand0.root1
Type: nand
Eraseblock size: 131072 bytes, 128.0 KiB
Amount of eraseblocks: 544 (71303168 bytes, 68.0 MiB)
Minimum input/output unit size: 2048 bytes
Sub-page size: 2048 bytes
OOB size: 64 bytes
Character device major/minor: 90:12
Bad blocks are allowed: true
Device is writable: true
- data partition: (is empty when flashed)

As you can see mtd8 can not be autoresized and attached.
What works however is: booting first with ubi.fm_autoconvert=0 and then enabling
it on the second boot.
Am I holding it wrong or is this a bug?
Thanks,
Steffen Trumtrar
