Kernel not able to mount ubifs file system from NAND after detection of SPI flash.

Hi All,

I am using two flash in my board with AM3352 processor.

1. SPI nor flash for password protection.

2. NAND flash for system booting.

kernel command line is

Kernel command line: console=ttyO0,115200n8 consoleblank=0 init=/etc/preinit root=ubi0:rootfs rw ubi.mtd=12,2048 noinitrd rootfstype=ubifs rootflags=sync user_debug=31 mem=128M mtdparts=omap2-nand.0:128k(SPL),128k(SPL.backup1),128k(SPL.backup2),128k(SPL.backup3),1m(U-Boot),512k(U-Boot-Env),1m(dtb),8m(Recv-Kernel),20m(Recv-Fs),1m(hwtst),16m(data),8m(Kernel),-(Rootfs) ethaddr=00:05:D7:09:7A:49

My all binaries are being preset in NAND flash.

U-boot is able to read kernel image from nand flash but the after when my kernel is detecting SPI flash and NAND flash at that time my kernel is not able to mount ubifs file system..

Kernel log is as :
