I have managed to not only get u-boot running (now with u-boot setting up the UART baud rate) but have also managed to get a 2.6.15 kernel with omap patchs to boot :-). I'm still having a problem getting the startup scripts to give me a login, but once I've fixed that problem I will make my modifications to u-boot and the kernel available (need to find somewhere to put them first) and then start working on getting USB up and running (the probe of the OHCI is failing for some reason).

Oh wow, that's fantastic news. Do you have access to the flash device ok? That would allow the use of JFFS2 which suddenly makes the whole thing a lot more useful for hacking about on.
Access to the modifications would be nice, even if they don't fully work. If you have nowhere to put them then I'm happy to host them on my site for you.

No JFFS yet but that shouldn't be too hard, I haven't tried it yet. With my modified pbltool with scripting support I can upload all I need in about 3 1/2 min.

That would be great. I am happy with my modifications to u-boot and pbltool but both need a bit of a clean up. I could create a patch for u-boot and the kernel. For pbltool I would prefer to just send you the source file as my modifcations have been extensive. Also I could put my buildroot & busybox configs on there so everyone can build their own rootfs, but I will also make all my images available.
All this probably will not happen till the weekend as I want a little longer working on the USB host.
B.T.W I now have a (slightly broken) shell.

This rocks, btw. Works fine on my E3 and I've been fiddling with the kernel a little.
I registered the MACH_AMS_DELTA type a while back with the ARM guys, so have added this to your patch and started trying to get some support for the flash devices in; I've got the NOR being detected, but it's non CFI compatible so I can't actually get mtd to talk to it.
I'd really like to get the NAND up and running; I think it's hanging off what Amstrad call latch2? 0xEC000000?
Anyway, my minor patch to use the proper Delta machine type is at:
http://the.earth.li/pub/e3/delta-20060222.diff
You'll need to patch u-boot to use a machine type of 862 as well obvious, otherwise the kernel won't boot.

That's great. Once I get the LCD up and running (almost there I think (famous last words ;-)) I'll merge my changes with yours and create another diff.
Martin is trying to track down the shell problem and has found that if you configure busybox to statically link it works.

Cool. Mine's against the one you distributed obviously. I've started trying to teach the omap-keypad driver about the E3's keypad layout, so if you get LCD working then that give us local console. \o/

I've worked on OpenEmbedded in the past; it should be easy to get it generating full images, but I'd like to get flash going before that ideally. I might take a look at a basic E3 target to help people get up and running if I find time though.

Just a question.. probably stupid... but while you're doing all this does it still work as a phone?
