What kind of MMC cards are you using? We're in the same boat and haven't been able to initialize Patriot 512MB cards. I've rewritten/added to the code for SD 2.0 (added 'sdinit' and an sd interface) and am seeing portions of the data dropped when I read blocks from a 512MB SanDisk SD 2.0 card. We're clocking at 10 MHz, running a 312 MHz PXA-270 (with turbo mode), and both cards work fine under our 2.6.18 kernel.
I think I know where I'd start looking ;-)
/* FIXME fill in the correct size (is set to 32MByte) */ mmc_dev.blksz = 512; mmc_dev.lba = 0x10000;
Btw, why do you need an sdinit command? It should be possible to tell the difference between SD and MMC cards automatically. In fact, I know it's possible because the Linux driver does it, and the at32ap7000 mmc driver I haven't submitted yet does it.
