Question Kernel Update

[Bluesbird]

Hello,
I have a Generell question to Kernel Updates. If I flash a new Kernel from sheeva.with-linux.com what happend with my installed Applications
and Personal Data/Configuration. I have just installed Zarafa on the Plug and it run fine, but I want upgrade the kernel to 2.6.31 without crashing my personal data and installed programms.

greetings Bluesbird

[odoll]

may I jump onto this train also, please.

Once sb has answered Bluesbird's question may I also ask for an answer to my related issue:

Re information provided in various threads/forums (thx!) I have successfully upgraded u-boot

Code:

U-Boot 1.1.4 (Sep 14 2009 - 15:36:37) Marvell version: 3.4.19

and I was able to get the original kernel booting from an 1GB SD card (ext2 /dev/mmcblk0p1: /uImage.sheeva.040309; ext3 /dev/mmcblk0p2: root-fs).

Nevertheless I struggle to get the 2.6.31 kernel to run. I tried to follow the instruction in the readme and i think I adapted them from the use in NAND to my setup using an SD.
But when booting I only get a message saying something

Code:

Uncompressing Linux... done, booting the kernel.

but nothing further happens.

Below are my boot parameters which work with the 2.6.22.18 kernel. Maybe sb can give a hint how to modify those working with the 2..31.6 version, please.

@odoll
Most times when it hangs after "done booting the kernel" it means that the environment variables that get passed to the kernel are not set correctly. In your case I can see you have some missing.

Near the top of the readme for 2.6.31 it says:

# This is a mainline Linux Kernel and you must set
# the mainlineLinux and arcNumber env variables in U-Boot
# and change the bootargs for a successful boot.
#
# setenv mainlineLinux yes
# setenv arcNumber 2097

You need to set these.

[odoll]

Ah sorry, when I wrote "I tried to follow the instruction in the readme" I ment that I set the parameters as instructed

# setenv mainlineLinux yes
# setenv arcNumber 2097

I also changed

bootargs_sd=console=ttyS0,115200 root=/dev/mmcblk0p2 rootdelay=10 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw

to

bootargs_sd=console=ttyS0,115200 root=/dev/mmcblk0p2 rootdelay=10 mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw

What I didn't do was adding "rootfstype=jffs2" as I use the root fs as ext3 on the SD card!?
And I didn't saved the parameters (saveenv) as I didn't wanted to make the changes permanent, yet.

I just hit "boot" after I made the (temporary) changes. Or should I have used "bootm 0x8000000" instaed?

[odoll]

hmm, tweaking a bit it works now, though I don't know what made the trick :-(

as far as I can tell I used the guideline http://plugcomputer.org/plugwiki/index.php/Install_Prebuilt_Kernels_From_sheeva.with-linux.com to update the kernel in my two plugs' NAND to 2.6.31.1.

though I made no [1] changes to the bootargs_sd parameter

Code:

bootargs_sd=console=ttyS0,115200 root=/dev/mmcblk0p2 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw
bootcmd_sd=setenv bootargs $(bootargs_sd); mmcinit; ext2load mmc 0 0x8000000 /uImage; bootm 0x8000000
bootcmd=run bootcmd_sd; run bootcmd_nand

[1]: (removed rootdelay=10 thou it work before already; and /uImage is symlink to /sheeva-2.6.31-uImage on the first small ext2 partition)

it now also boots the kernel and rootfs from the SD card :-)

just as a follow up - I further changed the bootargs parameter slightly back to

bootargs_sd=console=ttyS0,115200 root=/dev/mmcblk0p2 rootdelay=10 mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw

as though booting from SD I need some delay for my usb-drive to be recognised and to show up as device /dev/sda1 (for mounting it via fstab)

and though "nand_mtd" boots the "orion_nand" works as well and as don't know what difference it makes I'll stick with the recommended version ;-)
