That's good to know! :)

As far as I can see, we should be able to use the existing driver once
we adapt the code for the SA1100 features. The charging circuitry is
very similar to the other models as far as I can tell.
MMC/SD is more of a problem. There is one person with the specs who
could write the driver but he can't pass them to anyone else :-(.

You can build such an image with OpenEmbedded easily enough ;-). I guess
you're going to have to run it from the CF card though as the internal
flash isn't big enough and MMC/SD doesn't work?
Cheers,
Richard

Yep, it makes collie usable.

Agreed. I just need to find out why ADCs seem to return random values.

Did we ever have working MMC with open-source drivers (on collie)? I
thought we had MMC but not SD...

Well, provided I can get bitbake to work :-).
But I sense problems... I need CF slot for bluetooth card -- irda is
not really usable. I thought I seen some 16MB gpe images... and then,
there's RAM, too.

No open source driver for MMC or SD exists for collie and never has.

Maybe this will help.

Do you have any contact to author of this? It lacks any copyright/GPL
info :-(. Is wrt54g also sa1100-based?
> Maybe this will help.
Yes, thanks a lot.
