Correct way to install new Kernel?

[UnaClocker]

Hmm.. Found your guide.. Man I wish I had found that sooner.. Looks like I'll pretty much have to start over and redo my install.

Hi I used your guide to compile myself a new kernel (2.6.32.3 ) on the plug. However I want to have the same kernel on my usb stick. So I have put the uImage, vmlinux etc onto the /boot  of my usb stick, installed the modules and rebooted. It starts to load the kernel says it has read N bytes then hangs with no errors.

Anyone got any ideas? I have posted my environment , I added some boot commands to allow me to boot from a usb, mmc or nand depending on what device was inserted. Anyone got any ideas on getting a new kernel to boot from usb?

After re compiling the kernel again I get this

I fixed this issue. It had to do with loading the uImage. the kernal I had built did not need a uInitrd.

Is there a way that I can compile orion v2.6.31.1, from a usb drive, onto the nand?
Or am I going about this the wrong way?

Hello Doose,

Why not try writing your compiled uImage directly into the NAND partition of the sheevaplug? If you already have your compiled uImage, put it in your USB thumbdrive then do a nandwrite.

See below:


root@ubuntu:/mnt# ls
uImage
root@ubuntu:/mnt# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00400000 00020000 "uImage"
mtd1: 1fb00000 00020000 "rootfs"
root@ubuntu:/mnt# flash_eraseall /dev/mtd0
Erasing 128 Kibyte @ 3e0000 -- 96 % complete.
root@ubuntu:/mnt# nandwrite -p /dev/mtd0 uImage
...                                                 
root@ubuntu:/mnt#

Just ensure that you are modifying the nand partition for the kernel. After that perform a reboot.
Hope this helps. 

If I just take the latest precompiled sheeva-2.6.32.6-uImage from http://sheeva.with-linux.com , and put it on a directory or usb mount, I can run the above commands and have the new kernel ready after it finishes, with out the need of sheeva-2.6.32.6-Modules.tar.gz ?'?
If I'm booting of the nand, can I nandwrite the new kernel or I must boot from another source (like mmc or USB) to nandwrite the kernel ?
