 Attached are some patches to boot N810 with current linux-omap kernel and
 mount root on the internal MMC. I'm currently booting to Debian sid
 created with debootstrap, but this should work for any distro.
 
 I also put up a page for it with more notes:

 Only the first few patches are ready for merging, hopefully we can get
 all the attached hacks worked away soon..

I've pushed the camera fix, bluetooth and mmc patches below  I've
updated the remaining hacks on my website.

linux-omap vs N810

2008-04-27 Thread astralstorm 
Hello,
I'm having a major problem running linux-omap kernel on Nokia N810.
After correct build and flashing (tested by the use of self-built patched
Nokia kernel) the device seems to hang before framebuffer initialization,
then is rebooted by the watchdog. Manual FB update is disabled, I've
checked the configuration in many possible ways.

I'd like to hear about possible causes of that.

I do not have the serial console wired in (yet_, but would still like to
get debugging output. What would you recommend?

Do you have it in RD mode with no-lifeguard-reboots (check flasher
options)? If it's a reboot performed by the sw watchdog because some
component is crashing too many times, you could get a bit further in the
boot sequence, maybe to the point of ssh into the tablet.
