sdmmc / mvsdio and SDHC

[Sébastien Bocahu <lists%zecrazytux.net@localhost>]

Hello,

I'm trying to setup NetBSD on my OpenRD-base board (Marvell kirkwood based) with
boot from SD.

I first tried an old uSD in a uSD to SD adapter, but it was very slow, so I 
bought 
a brand new class 10 SDHC card. 

NetBSD 6.0 booted fine from the uSD, but it fails to boot from the class 10 
SDHC card,
and reports the following error:

ld0 at sdmmc0: <00000>
ld0: 7695 MB, 3908 cyl, 64 head, 63 sec, 512 bytes/sect x 15759360 sectors
ld0: 4-bit width, bus clock 50.000 MHz
...

/dev/rld0a: file system is clean; not checking
mvsdio0: CRC Error (0x4000)

...
and finally I/O error.

(with debug options: ld0: error 60)


Does anybody have a clue ? The card is working like a charm in a USB card 
reader.

Thanks,

Sebastien
