Find the images at http://ftp.nl.debian.org/debian/dists/wheezy/main/installer-armel/current/images/kirkwood/netboot/marvell/sheevaplug/.

See: http://www.debian.org/releases/wheezy/armel/
2  Linux Stuff / Linux distributions / Re: [IMPORTANT] Ubuntu 9.10(Karmic) and newer versions WON'T work on the sheevaplug on: May 29, 2013, 03:44:54 PM
I had Debian Wheezy working from an SD on my Sheeva Plug.

The build needs to be for armel and not armhf.  (the HF in armhf refers to hardware floating point, which the Sheeva does not have.)
3  Linux Stuff / General Linux questions / Re: Help: Missing article "Re-building the kernel and U-Boot - PlugWiki" on: May 29, 2013, 03:37:05 PM
I just got there on the first try:  http://www.plugcomputer.org/Documentation/howtos/re-building-the-kernel-and-u-boot/.

I should note that before that I had tried a few other links in the HowTo's that failed.  But on the second or third attempt I connected.

I think it may be related to DNS latency.

See what they recommend on the DENX U-Boot site, http://www.denx.de/wiki/U-Boot/WebHome.
5  Hardware and U-Boot firmware / U-Boot stuff / Re: Environment Variables on: December 28, 2012, 02:03:26 PM
There seem to be a lot of differences in the different plug types and versions of U-Boot.

On my SheevaPlug with U-Boot 2011.06 (Jul 03 2011 - 02:54:01), there is an "env" command:
Code:
Marvell>> ? env
env - environment handling commands

Usage:
env default -f - reset default environment
env edit name - edit environment variable
env export [-t | -b | -c] addr [size] - export environment
env import [-d] [-t | -b | -c] addr [size] - import environment
env print [name ...] - print environment
env run var [...] - run commands in an environment variable
env save - save environment
env set [-f] name [arg ...]

Marvell>>
I tried using it when I was getting some wierd behavior.I am sorry I didn't keep a copy of it.But one thing I have always wondered was what all those "x_bootargs*" and "x_bootcmd*" settings were for.  I didn't get an answer but I noticed that they were all re-created.

Now, I cannot boot the onboard nand.  So I missed something in my boot sequence.  Uimage and uinitrd seem to load and verify ok but it hangs on booting the kernel.

But the good news is that my new Debian testing version on an SD seems to work fine so far:
This is Debian 7.0, "Wheezy", "Linux debian 3.2.0-4-kirkwood #1 Debian 3.2.35-2 armv5tel GNU/Linux".

. . .
I think I will wait another two years for the next version of u-boot for the SheevaPlug. 

Debian for ARM posts a new version every 3 months.  The latest is June 2011.
8  Hardware and U-Boot firmware / U-Boot stuff / Re: uboot binaries on: August 08, 2011, 01:23:41 PM
It must be the new U-Boot that's being fussy then.

Oh well, as long as I can boot SD or MTD I'm happy for now.  I do plan to try other USB devices though.  Not only flash drives but also rotary hard drives.
9  Hardware and U-Boot firmware / U-Boot stuff / Re: Problem booting Sheevaplug off SD Card on: August 08, 2011, 01:19:24 PM
I don't know what I'm doing either.  I've only had my SheevaPlug about a month.

I had some misgivings the first time I used bubt to flash a new uboot.  But I had confidence in tftp since I had tried several different uImage kernels and uInitrd ramdisk images by loading them using tftp.

I hear what you are saying about PlugWiki.  Some of the pages are old or based on wrong information.  The good pages are hard to find sometimes.  It needs a better index or something.  I thought Martin Michlmayr's pages on www.cyrius.com were very informative.  Not only that, they are up to date.  Martin is on the Debian for ARM development team.  I got there by following a link on the Debian page, which is in turn one of the first links on the"main page" of the PlugWiki.
10  Hardware and U-Boot firmware / U-Boot stuff / Re: Dreamplug - "too many args" on reboot on: August 07, 2011, 10:39:25 PM
Is it the error where it also tells you that the maximum number is 16?  You can get around this with some "intermediate" variables.  On my SheevaPlug I have:

bootcmd=run bootcmd_sd; run bootcmd_usb; run bootcmd_mtd; run x_bootcmd;
bootcmd_mt1=ubi part nand0,1; ubi info; ubifsmount 'boot'; ubifsls; ubifsload 0x1100000 uInitrd; ubifsload 0x800000 uImage
bootcmd_mtd=run bootcmd_mt1; setenv bootargs ${bootargs_mtd} ${bootargs_std}; bootm 0x800000 0x1100000
bootcmd_mmc=mmc init; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd;
bootcmd_sd=run bootcmd_mmc; setenv bootargs ${bootargs_mmc} ${bootargs_std}; bootm 0x800000 0x1100000;
11  Hardware and U-Boot firmware / U-Boot stuff / Re: Uncompressing Linux - hang on: August 07, 2011, 10:25:25 PM
I went through all that too.  I don't know how many times I tried different kernels and different versions of U-Boot.  I finally had success by following Martin Michlmayr's instructions:  http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html.

You have to get the newest U-Boot:  http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html.
12  Hardware and U-Boot firmware / U-Boot stuff / Re: Problem booting Sheevaplug off SD Card on: August 07, 2011, 10:15:53 PM
I installed Debian "Wheezy" on my SD card.  See:  http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html.

This requires upgrading U-Boot first:  http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html.
13  Linux Stuff / Kernel / Re: uboot and kernel HowTo newer Version? on: August 07, 2011, 06:35:26 PM
You can get Das U-Boot source from DENX, http://www.denx.de/wiki/U-Boot/WebHome.  The kernel source comes from kernel.org.  The links I listed earlier are from the Debian for ARM project, http://www.debian.org/ports/arm/.

But don't ask me how to compile a kernel.  That would be new ground for me.  I plan to install developer tools and sources on my SheevaPlug on a working MMC/SD Debian setup.  If I have any success I will post on this forum.
14  Hardware and U-Boot firmware / U-Boot stuff / Re: DENX Open Das U-Boot on SheevaPlug on: August 06, 2011, 04:43:14 PM
No, you have to install first to USB or SD.  Then use "apt-get install mtd-utils" to get the ubi utilities.  In order to boot with root on ubifs, it has to be compiled into the kernel instead of loaded as a module.  Debian kernels 2.6.25 and later should include it.

I changed the layout on my SheevaPlug for a separate boot partition.  It is now:
Code:
root@debian:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00080000 00020000 "uboot"
mtd1: 02800000 00020000 "boot"
mtd2: 1d700000 00020000 "rootfs"
root@debian:~#

U-Boot 2011.06 (Jul 03 2011 - 02:54:01)
Marvell>> mtdparts

device nand0 <orion_nand>, # parts = 3
 #: name                size            offset          mask_flags

I intend to boot SD most of the time and save my NAND from too many writes.
15  Linux Stuff / Linux distributions / Re: NEW guruplug / openrd / sheeva installer images WHEEZY on: August 04, 2011, 06:41:02 PM
Clone it or just get a new SD card.  The Debian installer will know what to do with it.  It just has problems with MTD NAND partitions.

I used to know some Unix--but that was 20 years ago.  I feel like I have forgotton more than I ever knew.  So I just feel my way.
