It should be very similar to: http://chiana.homelinux.org/~marc/eib_sheeva.html

Site is inaccessible at this time. :(

I think the important part is under "Booting in the final system"

setenv mainlineLinux yes

I guess the kernel from sheeva.with-linux.com is considered a mainline Linux? What would be considered *not* mainline linux?

(too many people bricked their plugs so they have have an extra step and the sheeva installer writes a new uboot along with the kernel and filesystem to help prevent this.) Im sure you found the instructions for using the open u-boot.

Yeah, my plug isn't bricked. It happily boots the default ubuntu distro installed on the device. I just want to replace the kernel and root with fedora. I don't care where or not I update uboot. However none of the instructions I've found so far say how to do this. The only instruction I found for updating the nand said to use the sheevaplug-installer, which also wants to update uboot.

Do note in the instructions they are trying to use UbiFS instead of JFFS. Im not sure I would overwrite the U-boot with what they suggest either. but the procedure for overwriting the nand should be very similar.

Okay, n00b question here: what's the difference between UbiFS and JFFS, and why would I want to choose JFFS over UbiFS? (I know what JFFS is to some degree -- I used that back in the TuxScreen, but if the Sheeva wants to use UbiFS, what's wrong with that?)

I would try it with jffs first. You may have to compile kernel support to read the rootfs, but you should at least see your kernel boot. (and it will fail with something similar to "Kernel panic - not syncing: VFS: Unable to mount root fs".)

Ah, see, I'm trying *NOT* to compile anything, if I can avoid it. I don't want to be in the business of building my own kernels; that's what distributions are for. I just want to install the distribution on my system.

Is UbiFS part of the default kernel config, usually?

And as always if you actually figure it out. Update the wiki :)

Of course!

Hi,

I just received my SheevaPlug shipment yesterday, and today I've been trying (and failing) to install Fedora 12 onto it. I'm trying to set up the plug to boot off nand. Unfortunately the instructions on the wiki are pretty sparse. I'd consider myself a Fedora expert, but I'm definitely new to ARM and embedded systems (modulo some time I spent with a TuxScreen system about a decade ago).

I've downloaded the f12 root filesystem and modified it as per the wiki. I also downloaded the 2.6.32.21 kernels from http://sheeva.with-linux.com/sheeva/2.6.32.21/ (as per the wiki), but I have no idea if these are the "right" packages to use. I only chose this because it's the version of the kernel my F12 laptop is running).

Then I downloaded the sheevaplug installer (again, as per the fedora arm wiki), but of course it didn't work on my fedora-12 64 system; the problem was that runme.php needed "<?php" instead of just "<?" in order to get php to run... and even when running in an su environment, it still thought I wasn't root.

After trying to comprehend the sheevaplug-installer readme, googling to figure out where to find the uboot-custom.txt, and then finally getting the installer running, then I get the dreaded "No valid NAND flash driver found":

Luckily my sheeva is still running its original config. uboot is working (albeit with the default version):

** MARVELL BOARD: SHEEVA PLUG LE

U-Boot 1.1.4 (Jul 14 2009 - 06:46:57) Marvell version: 3.4.16

So... can someone help me wipe out the debian installation and install fedora-12? I think there are enough hits on the web to reflash my uImage, but I can't for the life of me figure out how to flash the rootfs.tar.gz into mtd2.

Any help would be greatly appreciated!

Thanks,

-derek

If you have uboot working and access to it then reflashing is better done from there than using JTAG.

Thanks. I've come to that realization and once I test the process I'll update the wiki appropriately.

You can use uboot to load the content to be flashed using either TFTP over network or USB stick.

Nowhere on the wiki does it really give a full set of instructions for how to do this. I THINK I've found some relevant instructions; once I run through them and test that they work I'll update the wiki with new instructions so the next user can have an easier time.

One note is that mkfs.ubifs isn't available in FC12 or 13; only in 14 is it available again. So one needs to backport the mtd-utils package in order to build a UbiFS image. I'll be sure to document this, too, once it's all tested.

Thanks!
