Excellent. I'd mapped it in in my patch, but not got round to
registering it with the 8250 driver. That's something I can cross off my
todo list. Do you have a patch to enable this I can add?

Currently I'm working on the boot process. I have u-boot supporting the
E3 NAND flash now, and reading the jffs2 fs (though very slowly; I think
I might try the kernel just in raw NAND). You can see a basic boot at:


I'm going to try wrapping u-boot up in a LDR block to see if I can get
PBL to load it, leading to a standalone boot process hopefully.

I believe Mark is looking at getting the mini keyboard to work.

Does anyone still have an E3 running 2.4 with shell access working? Any
chance of giving me the output of /proc/dfd with the phone on and off
hook? I'm guessing the hook switch hangs off a GPIO line.

AMS_DELTA_LATCH2_MODEM_CODEC isn't what you're looking for, is it?


                    I'm only here for the salad bar.
