Hi guys!
I'v just added a sd-card to my fon 2100 using the following guide:
http://www.larsen-b.com/Article/262.html
I've been looking all over the interwebs for info about setting it up with kamikaze 8.09 but all has failed.
I just get "mmc0: error -88 whilst initialising SD card" in dmesg".

Does any guru know what it might be?

Thanks in advance!

any reason for sticking to 8.09? 10.03.1 or trunk might be easier to debug.

It works now smile

I really didn't have any reason NOT to upgrade, so I did.
After trying this:

everything works!

All I/O operations take a lot of time, but i guess it's because the driver is bit-banging the spi-gpio bus.

Thank you MBS for making me re-think why I was running kamikaze smile

The discussion might have continued from here.
