1. When booting from eMMC, you would see only below directories:

#ls /dev/mmcblk*

/dev/mmcblk0 /dev/mmcblk0boot0 /dev/mmcblk0boot1 /dev/

mmcblk0p1

2. Insert SD card to SD card slot (SD1) and check your device again. You should

be able to see more directories. /dev/mmcblk1 is the SD card storage.

#ls /dev/mmcblk*

/dev/mmcblk0 /dev/mmcblk0boot1 /dev/mmcblk1 /dev/

mmcblk1p2

/dev/mmcblk0boot0 /dev/mmcblk0p1 /dev/mmcblk1p1

3. Create a file and copy to SD

#echo 123456789ABCDEF > test.txt

#dd if=./test.txt of=/dev/mmcblk1 bs=1024 count=1

seek=25118

0+1 records in

0+1 records out

16 bytes (16 B) copied, 0.000109331 s, 146 kB/s
