I have 4G SD card (not SDHC), this driver works perfectly with it. Card is Transcend 4Gb 150x. Output from dmesg: sdhci0-slot0: Card inserted mmc0: <MMC/SD bus> on sdhci0 mmcsd0: 3926MB <MMC/SD Memory Card> at mmc0 mmc0: setting transfer rate to 30.000MHz mmc0: setting bus width to 4 bits GEOM_LABEL: Label for provider mmcsd0 is msdosfs/WM_ILYA. I've been able to copy large file (diablo jdk 1.6) to and from this card, with no file corruption. I have another SD card, 2 Gb size, in my camera. It's from Kingston. It doesn't work: sdhci0-slot0: Card inserted mmc0: <MMC/SD bus> on sdhci0 sdhci0-slot0: Command error 1 (opcode 2 arg 0 flags 103 dlen 0 dflags 0) mmc0: setting transfer rate to 50.000MHz ... and no new storage devices appear. -- Ilya Bakulin <[email protected]>
