Hi all,
I am working on custom design board based on IBM405 PPC. I am using OpenBios
code and Linux -2.4.17 version from montavista. I have compiled the kernel
with JFFS2 support.
In linux/drivers/mtd/maps/redwood.c files, we have modified the partitions as
per our board
Our board is having 4MB flash and 32MB sdram.
#define WINDOW_ADDR 0xFFC00000
#define WINDOW_SIZE 0x00400000
we filled the redwood_flash_partitions structure as below
name: "Redwood kernel",
//"/dev/mtd0"
offset: 0x00010000,
size: 0x00110000
name: "Redwood OpenBIOS Vital Product Data",
//"/dev/mtd1"
offset: 0x00000000,
size: 0x00010000,
mask_flags: MTD_WRITEABLE
name: "Redwood filesystem",
//"/dev/mtd2"
offset: 0x00110000,
size: 0x002D0000
name: "Redwood OpenBIOS",
//"/dev/mtd3"
offset: 0x003E0000,
size: 0x00020000,
mask_flags: MTD_WRITEABLE /* force read-only */
i have created a jff2 image and flashed in the mtd2 block. But while booting
i am getting kernel panic
===============================================
kernel panic: I have no root and I want to scream
===============================================
how to tell the kernel that the root filesystems is in mtdblock2
Thanks & Regards,
rakesh
