My second and brand new Beaglebone Black was flashed to eMMC and worked fine with
BBB-eMMC-flasher-ubuntu-16.04.2-console-armhf-2017-07-14-2gb.img
following the excellent instructions of
http://derekmolloy.ie/write-a-new-image-to-the-beaglebone-black/#prettyPhoto
Next installed: sudo apt install linux-headers-3.8.13-bone86
because we have a driver that needs those 3.8.13 headers.
We have a script that calls update_kernel.sh --bone-kernel --stable
Afterwards the reboot will not start the kernel. My first board used 3.8.13-bone84 alright but is running from microSD not eMMC.
What is causing kernel start failure and how to fix it? Should I just replace the uname -r
in the driver Makefile with explicit 3.8.13-bone86 ???

Would really enjoy running from eMMC rather than microSD. While waiting for reply, I will try changing the driver Makefile to explicitly plug in 3.8.13-bone86, which means I have to reflash since otherwise I am stuck at boot prompt.
