Is anyone successfully using a rootfs on nand using jffs2 on OMAP3 systems?
I'm having little success. It used to work back in 2.6.26 timeframe
but seems to have broken sometime during 2.6.27.
Attempts to untar a rootfs result in ECC errors and then an oops.
Details below.
Is anyone else seeing this?
