I wonder how many simpads have died from mods or flash-writes gone wrong...

Today i exercised desoldering 8 sdrams chips from an old dimm..
and after that decided to risk the procedure on my CL4

tried to replace the CL4 chips with two 256M bit from the old dimm
i ended up trying to get the old two chips back in
At one point i thought i had it starting (with the old chips again), green led showed...
but nothing on the console and a after battery-disconnect no more response.. it does load the battery though.

i have some faint hope this thing could work again
but only with new, working ram chips
perhaps if i have a surplus dimm and a better desoldering method..
however the board is getting messy, two of the padds are loose, one broke off
tried to patch it up with pieces of copper strip and wire, but.. haha.. well..
i /hope/ the rest of the board isn't (too much :ph34r: ) affected,
it did stand up well against my MMC modding..

But all things considered.. i'm afraid i have to declare another bricked simpad.

btw, 'instruments' included a cheap soldering-iron, needles, screwdriver, tweezer and a big magnifying glass.

I finally did it, I bricked my Swisscom CL4. mad.gif

I re-flashed blupdater.img, to make sure it was that bootloader that I was using, and directly after that I uploaded the image Fred provided. Then I booted... Maybe that was stupid and I probably should have reset after uploading the bootloader. Anyway, the thing started booting, ran out of memory and halted. And now, aside from the recharching led and a brief flash of the backlight when it's turned on, it's dead.

I already had a JTAG cable and connectors soldered (~30cm, flatcable, 200Ohm resistors at JTAG connector), and I used both:
- The JTAG openwince-jtag deb package (0.5.1) and openwince-include deb
- Compiled JTAG 0.4 with the includes provided at openwince.sourceforge.net/includes

and tried:
jtag> cable ppdev /dev/{lp*,par*} DLC5
jtag> cable parallel 0x378 DLC5

Nothing, can't init the thing, tried it on an Ubuntu and Debian Sarge box. I suspect Sascha was right, perhaps the Swisscoms can't be JTAG'ed?

Just a warning sad.gif

I have the whole OE/Bitbake thing running and last weekend build a few images. this gives me two problems:

1) The standard GPE image is about 20MB, and won't fit on my CL4. Last year there were some opensimpad images available in XXL and light versions. I browsed through the org.openembedded.dev files but I couldn't find any reference how to customize the GPE image like this. What would be the way to do this? The OE wiki doesn't seem to touch this subject either.

2) Also, I modded a MMC into my simpad and tried if it would show up when using a fresh boostrap-image. But the module isn't build. I can find all kinds of references to MMC and CONFIG_MMC but I'm not sure how to 'enable' the mmc.so to be build.

I realise I might take these questions to a broader OE audience, but I'm hoping there are still some opensimpad developers lurking here that can teach me a few tricks and/or kick me in the right direction.

What I'm aiming for is to use the CL4 as an ebook reader, so primarily I'm looking for a decent PDF reader and for convenience a recent browser (JS and XMLHttpRequest stuff so I can create some self-contained HTML/JS applications for some notetaking).
Digital PIM never did it for me (I prefer paper) so I won't need those apps. I've searched for the right ebook hardware for years but these things never seem to break through and very often only support some obscure proprietary format. The CL4's that are flooding eBay come very close to what I wanted, just some software and extra memory and I'll be very happy.

And as for the OpenSimpad project, I think it's a shame it's stalling like this and I'd certainly be wiling to put some time in it --I'm stuck with this thing ;-)
I'm more of a web/python dev monkey so I don't have much to contribute in C/C++ and what else, but as soon as I learn something here I think it should go on the opensimpad wiki to at least show there's still something going on and I'd be pleased to offer images. All in good time ofcourse and first a decent image, but I'm just saying opensimpad won't be over if I can do anything about it. (maybe it could fit into the Angstrom project? I need to ask those guys...)

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

I am trying to find a serial USB cable for a SL4 simpad. I read somewhere that The SLC uses a S25/35, which I'm guessing is a datacable for the C25/S25/C35/S35 phones.

Can anyone confirm this?
