It is helpfull to have a hex calculator to determine memory map.
burning new image: ...
The whole idea is to make an image using openwrt build.
After the build is complete then we get the size of the image and the re build it with make to establish the correct memory map.
!!CAUTION THIS IS JUST A SAMPLE MEMORY MAP!!
current imaging
start hex size hex end hex name comment
0x00000000 0x00100000 0x00100000 uboot uboot takes the first block 1.048576 megs

Partitioning
To list the current partition table, run the command mtdparts
Marvell>> mtdparts
device nand0 <orion_nand>, # parts = 4
#: name size offset mask_flags
0: u-boot 0x00100000 0x00000000 0
1: uImage 0x00400000 0x00100000 0
2: rootfs 0x02000000 0x00500000 0
3: data 0x05b00000 0x02500000 0
Deleting partitions rootfs and data and adding new blocks:
mtdparts del rootfs
mtdparts del rootfs_data (note first time in it is just mtdparts del data)
Resize to fit the new image.
(for example on a new rebuild. Caution!! this is a sample. Don't just copy. Check and determine the size.)
mtdparts add nand0 0x009e0000@0x00500000 rootfs
mtdparts add nand0 0x07120000@0x00ee0000 rootfs_data
We check with mtdparts:
Marvell>> mtdparts
device nand0 <orion_nand>, # parts = 4
#: name size offset mask_flags
0: u-boot 0x00100000 0x00000000 0
1: uImage 0x00400000 0x00100000 0
2: as per new
3: as per new
You save everything and reboot:
Marvell>> save
Saving Environment to NAND...
Erasing Nand...
Erasing at 0xc0000 -- 100% complete.
Writing to Nand... done
Marvell>> reset
4) Installing OpenWrt:
Never start the command "nand erase" without options, it will erase all your nand, including uboot.
we modify several variables:
setenv bootargs console=ttyS0,115200 root=/dev/mtdblock2 rootfstype=jffs2 panic=10
setenv bootcmd 'nand read.e 0x2000000 0x100000 0x400000 ; bootm 0x2000000'
setenv mainlineLinux yes
setenv arcNumber 2097
setenv serverip 192.168.1.37
setenv ipaddr 192.168.1.38
saveenv
reset
(note sample as per the above new build, don't just copy and paste this one.)
You install the kernel:
tftp 0x2000000 openwrt-kirkwood-uImage
nand erase 0x00100000 0x00400000
nand write 0x2000000 0x00100000 0x00400000
Then the rootfs:
tftp 0x2000000 openwrt-kirkwood--jffs2-128k.img
nand erase 0x00500000 0x009e0000
nand write 0x2000000 0x00500000 0x009e0000
It will become void rootfs_data / overlay at boot:
nand erase 0x07120000 0x00ee0000
