Simpad Bootloader 'load Root' Problem

[Berend]

Hi all!

I'm looking for a bootloader to get linux working on my new Swisscom ScreenPad (a CL4 simpad/16MB flash). The version I'm using now is the
blupdater.img provided with opensimpad-0.9.0rc1 (forumpost:
http://opensimpad.org/opensimpad-forum/vie...1f2f538fa#3613).

It works for the most part, however, when I try to load a rootfs.jffs2 image it fails when erasing flash at 0100000 (=16), see serial output below.

The problem is similar to a report (Januari 2005) at the old fora. Chris was looking into this at the time but I can't find out if he found a solution.
The old post: http://opensimpad.org/opensimpad-forum/vie...61f2f538fa#3632

So I'm completly stuck, does anyone have a working CL4 bootloader / could anyone tell me how or where to get one? Perhaps I could use some older files and then upgrade? I hope anyone with a CL4 can enlighten me.

Thanks, Berend

well, i have an sl4...
but if i remember right, the new bootloader, (hh.org, the one u installed with the image blupdater.img), only works on 32mb flash devices, u should find something about it, if u read all the way through the old forum.
i also think, most jffs2 images are bigger than 16mb, so how could they possibly fit?
maybe if u use

http://devernay.free.fr/hacks/opensimpad/2...21.rootfs.jffs2

if i am right, and only 32mb models work properly with the hh.org bootloader, then u have to go back to the old Siemens-BL, see the wiki on opensimpad.org for that.

the best image for me so far (mainly used as webpad) was the 0.8.1-1 anyways, but i did not test the newest ones on devernay...

I read about the 16MB issues on the mailinglist and it seems this was just never resolved, but I didn't get the impression it was impossible. And the booloader is the main issue, after that there are some images that'll fit.

I could go back to original Siemens and WinCE, i did for a while, but the PDF reader has some issues and I couldn't even find a calculator, so I'd really like to try linux.

thanks, Berend.

Me too...
I had WinCe 4.1 on my Simpad but was not able to get a reliable wireless connection with a netgear ma401. Tried all the drivers that were available but...
Next thing is, I would like to have an email client capable of imap so I can work with my home server from all workstations. I want the simpad mainly as surfpad and email client so that the 16MB should be sufficient.
Happily looking forward to things to come and eventually ready to do some things myself.
