microSD card[edit | edit source]

microSD card on connector J21, if present, will be associated by the Linux kernel to the mmcblk0 device:

[   24.100643] mmc0: new high speed SDHC card at address 1234

[   24.113268]  mmcblk0: p1 p2

Once detected, it can be mounted and accessed via usual Linux commands:

root@bora:~# mount /dev/mmcblk0p1 /mnt/mmcblk0p1/
root@bora:~# time cp LibreOffice_4.1.1_Win_x86.msi /mnt/mmcblk0p1/
