[ppc40x] can't mount system during boot

Reported by: Marcin Tabakiernik <mtabakiernik@…> Owned by: kaloz
Priority: high Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: ppc40 magicbox Cc:


I can't get to start OpenWrt on ppc40x device - Magicbox v2.
Using default config I get error during boot, that root fs system can't be mounted.

I can't figure out why. Tried changing a lot in kernel but it didn't help.

The error I get:

ffc00000.nor_flash: Found 1 x16 devices at 0x0 in 16-bit bank

ffc00000.nor_flash: Swapping erase regions for broken CFI table.

Thats because the kernel got larger than 1Mb. The rootfs MTD partition begins at the 1Mb (0x100000) but there is stille the kernel. I updated the device tree an the image makefile to fix this.

So obvious!
Why didn't I come on that...
I found another bug for magicbox. While using jffs2 image during boot system is being erased. Changing erase block size (the bs parametr in Makefile) from 128 to 64 helped.
Later I'll post patch.
