NAME

sdcard - SD/MMC memory card driver
 

DESCRIPTION

The sdcard memory card driver supports MultiMediaCard (MMC), Secure Digital (SD), and Secure Digital High Capacity (SDHC) memory cards. It uses the blk2scsa(7D) service to present these cards to the system as SCSI disks on a virtual SCSI bus, creating a child device to be serviced with sd(7D). Each card appears as its own SCSI LUN. Cards are hot-pluggable and removable.  

DEVICE SPECIAL FILES

Disk block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk. See sd(7D).  

IOCTLS

See dkio(7I)  

ERRORS

See sd(7D) and blk2scsa(7D). Additionally, sdcard may issue the following warnings, which indicate a failure to identify the card as a supported type:

"Unknown SD CSD version (%d)"
"Unknown MMC CSD version (%d)"
"Unknown MMCA version (%d)"
"Card type unknown"

FILES

Device special files for the storage device are created in the same way as those for a SCSI disk. See sd(7D) for more information.

/dev/dsk/cntndnsn

Block files for disks.

/dev/rdsk/cntndnsn

Raw files for disks.

/kernel/drv/sdcard
