Hi, all:
Sorry for dropping this stupid question. But, with my TF card plugged in, I checked the memory of BBB (Refer to the bottom command)
It looks BBB’s memory is quite messy.
On my 32Giga TF Card, namely, mmcblk0, I got /dev/mmcblk0p1 and /dev/mmcblk0p2
On eMMC, namely, /dev/mmcblk1, I got dev/mmcblk0p1, dev/mmcblk0p2, /dev/mmcblk1boot0, and /dev/mmcblk1boot1 .
Just wondering, why on eMMC, there are /dev/mmcblk1boot0, and /dev/mmcblk1boot1? What for?
And, it looks that my eMMC is only of 2Giga? I was thinking the newest BBB is of 4Giga eMMC???
Cheers
Pei
