Get detailed information about microsd hardware?
I have a 16GB microsd card attached as /dev/mmcblk0, i want to see more information about the cards capabilities, so far i've tried looking here:
This doesn't seem to work for microsd cards;
Code:
root@pi:~# hdparm -I /dev/mmcblk0
/dev/mmcblk0:
HDIO_DRIVE_CMD(identify) failed: Invalid argument
Same here, not sure about -d option though;
Code:
root@pi:~# smartctl -i /dev/mmcblk0
smartctl 5.43 2012-06-30 r3573 [armv6l-linux-3.12.30+] (local build)

/dev/mmcblk0: Unable to detect device type
Smartctl: please specify device type with the -d option.
Use smartctl -h to get a usage summary
Some information can be found here, but it's not very detailed
Code:
root@pi:~# ls /sys/block/mmcblk0/device/
block/ date fwrev name preferred_erase_size subsystem@
cid driver@ hwrev oemid scr type
csd erase_size manfid power/ serial uevent

Basically i'm after the full spec's of the card. Usually i'd get it with hdparm -I for a hard drive. Not too sure how to go about it with a microsd.
Thanks.. |
