is there way to perform factory reset BPI-R2?
Can I clear all eMMC and not to brick the board?
I found this great blog - http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:storage , but I can’t figure how to clear eMMC…
I did some nasty things to my BPI and I want start from the beginning with fresh board (system).
Thank you for advice!
imho you can set the partitionconfig with mmc-utils/uboot to 0x00 and write with dd from /dev/zero to mmcblk1 (make sure this is your emmc)
Yes，frank is right，you can program emmc again to reset it，here are detail operation steps ：BPI-R2 new image : ubuntu 16.04 V1.2.1 BT and WIFI AP mode are working fine 2017-11-27
you can find it in FAQ.
Thank you guys
BPI-R2> emmc pconf 0x00 from u-boot
and than from Ubuntu MATE:
root@bpi-iot-ros-ai:~# dd if=/dev/zero of=/dev/mmcblk1
and everything is good as new!
