Ok, that was my fault. I had compiled Ramdisk support as module. Now, i've compiled it normally, and it boots (tried with initrd from htc wallaby). Better - I've also enabled driver for Intel PXA MMC host, and it see my card
Now I'm partitioning my SD card - i'll try to put mp900c userland on it
Well, it's booting from SD
only one problem - it looks like keyboard is driven differently than in MP900c - it's not working.
Sad thing is that WinCE is damaging ext partition - don't know why it shows it in My Computer, and after that linux kernel doesn't recognize root partition. Only way i currently found is to insert SD card quickly after kernel start booting.
Well, Xorg is working
Touchscreen also. Here's vid:http://www.youtube.com/watch?v=U89x2-7ltDQ
Only issue is still keyboard - noone of hw buttons is working, and when I press any of them ts driver semms to hang.
My config file: LINK
Other thing I found - USB slave is controlled by... isp1161a1 (the same as in MP900, but Maui doesn't have USB host (yet?
