There is a beagleboard project how to interface
the OMAP processor:

memory for configured ALARM(s)

[Matthias Apitz]

Hello,

Where does the FR stores the configured ALARM(s) so that they can wakeup
the FR and let it boot? Is there a way to inspect this from SHR-t?

The background of my question is that I have installed SHR-t on an used
FR device and never configured any ALARM in it (and SHR-t does not show
any), but today morning at 5 o'clock it kicked me out of my bed (and my
wife said that she will do the same with the FR if it would happen again
:-) )

Thanks

matthias

[qtmoko] Alsa scenarios - Where do they come from ?

[Gilles Filippini]

Hi,

Quoting debian_rootfs_howto from qtmoko v35:

But these files in qtmoko are significantly different - including
control names - from those in
 which don't
work at all with qtmoko.

How does it come?

Thanks in advance,

Names changed with newer kernels which rendered older statefiles
unusable.
