Linux on a CL4, which bootloader?

Hi,

my new Simpad arrived yesterday, a Swisscom CL4. and I spend the
evening trying to get linux and GPE running on it.

It was very cool to finally hold one btw, she's got a bigger behind
than most photo's suggest, but I've been whishing for a handheld
computer with a decent screen for a few years or so, and I'm not very
picky at this price.

When I got the hh.org image booting (penguing on screen) and I was
told to reset, it seemed to die horribly (screen fading away in a
_very_ ugly way). At first I thought it died (only garbage over tty),
but after some reading at the fora I got a hh.org boot prompt and I'm
able to use minicom to transfer files... Wohoo! It's my first simpad,
so please bear with me. :)

Then I tried loading different images and even went back to the
siemens bootloader to erase flash first, but I can't get any
rootfs.jffs2 image to load-not even a small bootstrap: after the
upload it starts erasing and fails at 01000000 giving an erase error.

the partition command spits out this:

boot> partition
npartitions=3D00000003
bootldr
  base: 00000000
  size: 00040000
   end: 00040000
 flags: 00000002
root
  base: 00040000
  size: 017C0000
   end: 01800000
 flags: 00000018
home
  base: 01800000
  size: 00800000
   end: 02000000 << ?
 flags: 00000000

I don't think that'll fit at my 16MB flash. My guess is it's the SL4 table?
I think I got my bootloader at the old forum, here from the 0.9.0rc1
'release': http://opensimpad.org/opensimpad-forum/viewtopic.php?p=3D3613&si=
d=3D7097574a207e7ea99707f1a503a52f7a#3613

My best guess now is that the partition table is hardcoded in the
bootloader image and it can't be changed from the bootprompt?
(deleting /home etc. has no effect).

So I'm stuck at the boot prompt and my simpad is acting like a zombie
with one green led right now. I'd like to get it alive, anyone care to
give me a few pointers?


regards, Berend
