Boot From NAND not supporting with 2.6.35 Kernel

Nagraj — Tue, 17 Sep 2013 05:56:55 GMT

When Im using the kernel 2.6.31 Icould easily boot from either SD Card or the NAND Flash , i.e followed the same procedure of freescale to copy the kernel and Filesystem to NAND using ubifs with the LTIB command line as below:

noinitrd console=ttyAM0,115200 ubi.mtd=1 root=ubi0:rootfs0 rootfstype=ubifs rw gpmi

But when trying to the same with kernel 2.6.35 , there is a kernel panic as shown below?

fsl-ehci fsl-ehci: irq 11, io base 0x80080000

fsl-ehci fsl-ehci: USB 2.0 started, EHCI 1.00

Can somebody help me in the bootable procedure to copy the kernel and filesystem to NAND ? Please let me know if any changes are also required with the configurations other than that are mentioned in the reference manual?

Some instructions for ubifs are here: https://community.freescale.com/thread/254021

You might be missing "rootwait" parameter in kernel command line.
