The new version does not contain that error message - but you may need to alter it slightly in order to build without errors, as andiator reported.

Yes, I don't get the non-aligned buffer error anymore, but the read error given by the bootloader is still there. Now I got it to boot, but it's still a matter of luck... (and I definitely build it with the new driver...)
andiator: I've a little home-server running on a nslu2 with debian ;) if you just need a little space for things like that, I can arrange that... 512kbits upstream though
andiator:
Thanks carsten, but one hour before your post there was a parcel delivered to me - and what was inside? nslu2! Â ;D and my upload is 1024 Kbit.
But back to topic. Did you rebuild the bootloader with the newer ata-driver? And did you do the ../tools/mktccboot ... stuff?
I played again with buttons and copied/inserted the touchpad test code into button_read_device(). Well, the virtual buttons work normaly, so the problem has to be the adc, but I don't get it since the code is so simple.
I uploaded the new binaries for testing. This touchpad stuff is really only for testing. It will be done right in future, so don't say it works badly  ;)
In bootloader screen simply tip on the screen to get further.

I'm up and running now as described in the previous posts and the majority of the demo plugins work fine. The only thing I've come across so far that I don't think has been mentioned is that the lcd seems to cut off a couple of rows from the top and displays them at the bottom.
I'm really impressed, you've done some great work shotofadds.
I probably won't be able to help much with the coding but I will certainly start taking a look at the weekend.

Yep, that's a consequence of not fully understanding the LCD controller initialisation. I get the same here (but not every time) - it'll be fixed eventually. Â :)
I'll hopefully have more time to work on this next week. My priorities at the moment are fixing the button/ADC code, getting the flash driver into a reasonable state and reducing the compiler warnings so we can get the D2 builds added to the Rockbox build table. Shouldn't take long... ::)
EDIT: The updated NAND driver has now been committed so I've removed it from the previous post. "svn update" is your friend. :)
Llorean:
Any particular reason for decreasing the CPU frequency? Seems like it should stay at "max" until scaling works, to maximize the range of things that won't suffer from CPU speed limitations.
