I'm trying to get my root filesystem into the BeagleBoard's NAND
flash. I followed the recommended procedure outlined here:
When I extract my tarball onto the partition, I get a few errors like
mtd->read(0x44 bytes from 0xf9406fc) returned ECC error
However, most of the files appear to be okay (I can run my test
When I do "sync" and unmount the partition and then remount it again,
every read seems to be uncorrectable; my console gets flushed with ECC
I'm at a loss here, since creating a jffs2 image with mkfs.jffs2
produced the same errors. Since there are so many things that might
have caused this, I desperately need a pointer in the right direction.
Some additional info, please ask for more if that might help:
I'm using a linux-omap3 kernel from the arago git repository and
checked out the 18.104.22.168-rt29 tag (I need a PREEMPT-RT kernel). The
rootfs is built from scratch and contains only BusyBox (1.18.4 built
from source), libc and qt. The MTD-utils used on the BeagleBoard are
the ones built into BusyBox. I'm using mdev to manage devices. My
toolchain is CodeSourcery arm-2009q3 (linux-gnueabi).
The kernel has been reconfigured many times, this would be my first
guess at what is wrong. When I started using it, MTD support wasn't
even selected, but I don't really know, which options have to be
configured for an OMAP processor. If it helps, I can provide my kernel
Any help would be greatly appreciated!
