Dear Schleifer, Alexander,
Hello Reinhard,
thanks for your reply. I checked the register settings and sorted out, that the SDCBUS was initialized in 4-bit mode by the bootstrap.
So I added the explicit initialization when port A is used:
#if defined(CONFIG_ATMEL_MCI_PORTB) mmci_writel(SDCR, (MMCI_BF(SCDSEL, 1) | MMCI_BF(SCDBUS, 0))); #else mmci_writel(SDCR, (MMCI_BF(SCDSEL, 0) | MMCI_BF(SCDBUS, 0))); #endif
Arghh, thats why getting the "geometry" worked, but not a block read.
And you were right, the new driver would have handled that correctly :)
Since currently the new driver is among the "newest" in my series of changes here, I'll have to try to rebase to get it to the "oldest" position.
Reinhard
