As an answer to the last part of your blog: The ipv6 code uses unaligned access. Måns has patches to make it selectable.

Hello,

I've been looking at inittab and the various rc directories trying to figure out what happens when Angstrom boots. Could someone please tell me what I need to do in order to have a script run upon boot up.

Thanks

David

Hello all!

Can anyone suggest where I might look or send me example code on how to implement some sort of timing scheme? I

I'm getting data from an adc via spi and need to ensure stable sample timing. I'm using angstrom 2.6.32 and code sourcery.

Thanks

David

Hi David,

What exactly do you want to implement (frequency, accuracy etc.). In
any case POSIX timers might be interesting to you.

Cheers,
Max.
