It is, I just looked in the wrong place. Sorry about that. I have installed Marvell's u-boot from git and booting Orion kernel now. Thanks for the explanation. Makes perfect sense.

Thanks for the pointer. It's definitely there, but it was nicely tucked away and hidden in u-boot-3.4.16.zip.

Since there were so many zip files, I had unpacked the zip files initially. I must have thought the u-boot-1.1.4.tar.bz2 was the product of the u-boot-3.4.16.zip. So, I looked in the wrong place. Doh!

Thanks much!

I am trying to locate the doimage utility used to generate the u-boot-*_400db_nand.bin. The Das U-boot article http://www.plugcomputer.org/plugwiki/index.php/Das_U-boot_plug_support indicates that it is part of the DevKit CD, but I couldn't find it.

At the moment, I have built Marvell's development U-boot from the git repository and would like to burn it to the NAND flash. I am using OpenOCD to load U-boot in memory to run. I tried writing to the NAND using OpenOCD's "sheevaplug_reflash_uboot" command to write uboot.bin, but it doesn't boot. The only way I can load the development u-boot is by loading it in memory.

Here is the OpenOCD's TCL function for re-flashing u-boot:

proc sheevaplug_reflash_uboot { } {

        # reflash the u-Boot binary and reboot into it
        sheevaplug_init
        nand probe 0
        nand erase 0 0x0 0xa0000
        nand write 0 uboot.bin 0 oob_softecc_kw
        resume

}

The only thing I can think of is uboot.bin expects to be in _nand.bin format. I was using the u-boot.bin that was generated from objcopy. Thanks in advance.

Hi. I'm seeing exactly the same problem. The weird thing is I am able to set the console environment variable if I'm using the original u-boot that came with the 1.0 SDK. If I try to use 1.2, I am not able to save the console environment. However, I could set other things such as ipaddr and serverip so it is able to write to flash. Very strange.

I tried doing a resetenv and doing a setenv followed by a saveenv, but the console value goes back to default settings after a reset.

Marvell>> printenv console
console=console=ttyS0,115200 mtdparts=nand_mtd:0x100000@0(uboot)ro,0x0@0x100000(
uImage),0x1ff00000@0x100000(rootfs)rw
Marvell>> setenv console
Marvell>> printenv console
## Error: "console" not defined

Marvell>> printenv console
console=console=ttyS0,115200
Marvell>> saveenv

Hi all. I seem to have a problem connecting the SheevaPlug to a AirLink Gigabit 8-port switch. I get no link. The only way I can get a link is if I connect the SheevaPlug to my Linksys router which has a 10/100Mbit switch. It looks like some kind of compatibility issue with the PHYs. Has anyone else experience this? Also, I was wondering if there is a way to force the ethernet mode in U-Boot? Thanks.
