Hello,
I am working on booting Linux on an embedded platform
(AT91SAM9260). In this I am using a JFFS2 flash file system . I have
created a Jffs2 file system using mkfs.jffs2. I have written this file
system on a particular sector in the NAND flash. I have made three
partitions in Linux , and the third partition is starting from where i
wrote the JFFS2 file system. I have given the kernel parameter as
*mem=64M console=ttyS0,115200 noinitrd root=/dev/mtdblock3 rw
rootfstype=jffs2. *During Linux kernel boot up, it is creating 3
partitions ,but at the end it is giving a kernel panic. The boot process
is given below
