I updated my Linkit Smart 7688 to openWRT 18.06.2.
I then followed this manual to Mount the root FS on the internal SD card because the flash of my device is not sufficient.
The second command leads to a error
root@openWrt:~# mkfs.ext4 /dev/mmcblk0p1 mke2fs 1.44.1 (24-Mar-2018) The file /dev/mmcblk0p1 does not exist and no size was specified.
wondering if thats the right way to get the OS to the SD card...
Any ideas how to do that right?
