[U-Boot] Problem in writing jffs2 fiesystem

Hi all,

I am running u-b00t-1.6.6 on custom at91sam9263 board. Now i am able to boot, jffs2 filesystem with linux-2.6.20 kernel. but the procedure i am using to burn is jffs2 is : 1)boot the linux kernel with ramdisk 2)erase the flash partition using $flasheraseall -j /dev/mtd1 3)writing the image using $nandwrite -p /dev/mtd1 rootfs.jffs2

The above procedure works well for me. But when i try writing the jffs2 filesytem in uboot prompt its not booting (kernel panic). In uboot i did this way:

1) tftp 21100000 rootfs.jffs2 2)nand write.jffs2 21100000 0x200000 0x(hex add of displayed by tftp)

What is the write of doing this? - Regards, Naveen Application Engineer Innovate Software Solutions Pvt Ltd., Bengalooru
