uBoot for OX820 / NAS7820 with ext2 support...

[jedie2]

We are searching for a working uBoot with ext2 support for our P89626 NAS. Our default uBoot is old v1.1.2 only with TFTP...

The P89626 NAS used the PLX-NAS7820... The idea is that we try to use a newer uBoot from a other PLX-NAS7820 device. Does anyone know a download source for a newer uBoot?

The Iomega HMNHD Cloud Edition doesn also use the old v1.1.2. Does anyone know if it support ext2 ?

As the one person doing any u-boot development for the PLX 7820 (publicly at least), I can say this: the ext2 support is buggered up. Raw ide reads however, work rather well, and I have yet to attempt to use FAT.

Would your folks happen to have any u-boot familiar developers? I can assist them in getting it working, and with the layout provided in my prior post about pure-SATA boot chain, it is fairly easy to test. The u-boot sources, are of course open. I have disk, NAND, network and *maybe* fatload working. USB is just screwed.

Please, do feel free to find me in IRC.

We search for a way to load the ArchLinux kernel from disk and not only via TFTP...

One developer is active here: http://github.com/michaelkebe/u-boot-medion-p89626/ He has a problem, see: http://www.mail-archive.com/u-boot@list ... 73361.html

This is something that I have not run into since I have not attempted to port up, yet. I wanted to get as much as possible working, prior to moving up.

Don't fix what isn't broke, yet.

Make it sence to try uBoot from viewtopic.php?f=29&t=2146 via TFTP ?

[WarheadsSE]

You can try it. I won't promise that it will work, but.. you can try.

Seems not to work:
$this->bbcode_second_pass_code('', 'Filename 'u-boot.wrapped'.
Load address: 0x61000000
Loading: ##########################
done
Bytes transferred = 129852 (1fb3c hex)
## Booting image at 61000000 ...
Bad Magic Number
$
')

Ah.. right.. sorry. I'd have to get you the normalized u-boot(.bin) .. The one in that package is wrapped for loading by the stage1 bootloader (proprietary, I can't give that wrapping mechanism out)

[jedie2]

$this->bbcode_second_pass_quote('WarheadsSE', 'I')'d have to get you the normalized u-boot(.bin)

Well, let me put it this way: It will ask for chunks in 512, you disk will normally oblige. I have not tested this
