Are you working with a real MMC card or with an SD-card? I myself am not able to get several SD-cards working, even though SD-cards should be able to talk the MMC-protocol (AFAIK). What I do have is several MMC-cards working properly, but I have to add a small side note. I am using the AU1100 processor on our own designed board. This AU1100 processor has a different DMA controller than the AU1200 and AU1500. Unfortunaly the mmc driver is written to use the DMA driver for the AU1200/AU1500 controller and not the DMA driver for the AU1100. This is why I have a slightly altered version of the au1xmmc driver. This version is currently using pio mode instead of DMA. In the future I want it to correcly use the right DMA driver depending on the processor, but time constrains keep me at this moment from doing that. Also it is a little bit addapted for our own hardware, which is like I mentioned before not the DBAu1100 development board. If you have trouble with MMC-cards too I'm more than willing to send you the patch, but it probably needs some tweaking on your part. That's why I do not yet attach it to this mail. Just ask me personally for it if you want to try it out. > Before I go about to trace the problem I'd like to know if > other people see this problem too or if it's specific to my > system. With the SD-cards the driver indeed got no answer on the CMD9 request. So yes, I have the same problem on the AU1100 with the 2.6.16 kernel. -- $ cat ~/.signature Freddy Spierenburg <freddy@xxxxxxxxxxxxxxx> http://freddy.snarl.nl/ GnuPG: 0x7941D1E1=C948 5851 26D2 FA5C 39F1 E588 6F17 FD5D 7941 D1E1 $ # Please read http://www.ietf.org/rfc/rfc2015.txt before complain!
