Subject: au1100 MMC support
Date: Wed, 9 Aug 2006 12:29:50 +0200 [thread overview]
Message-ID: <20060809102950.GA2531@enneenne.com> (raw)
Hello,
I'm just working on MMC support for au1100 CPUs. I patched au1xmmc.c
in order to disable DMA support (which is different from au1200 and
au1100) and forcing PIO mode.
Both MMC controllers of au1200 and au1100 seems similar to me...
Here what I get when I insert the card:

It seems that the driver doesn't recognize the card.
Any suggestions? Do you think that the controller is talking with the
card?
Thanks,
Rodolfo
