Hello everyone,
I have been using the Beaglebone Blue for over 3 months now without any problems until now. The board typically boots off the SD card, primarily because I needed the extra space for a ROS installation. I originallyt used the latest Debian Jessie image for a couple of months and then created a new SD card (early December 2017) with the new Debian stretch image and then setup ROS (from source).
EMMC does not boot anymore
