Hi, i’m having problems to boot from EMMC on BPI M2 Ultra.
I’m using 2017-08-27-debian-9-stretch-lite-preview-bpi-m2u-sd-emmc.img and everything was perfect from SD card, but once i used: sudo dd if=/dev/mmcblk0 of=/dev/mmcblk1 bs=10MB status=progress, to burn the image from SD to EMMC, the M2U now boots from EMMC but on Read-only file system, so, all command can not write the emmc partition and that way is useless for me.
is there any way to change that write protection on my EMMC to be used like the SD card? i don’t wan to work with the SD, just with EMMC.
