When I boot Stretch with the /boot/uEnv.txt containing this:
dtb=am335x-boneblack-emmc-overlay.dtb
Then the SD card will start booting, all the LEDs pause, then restart and it boots from emmc instead! Is this a bug?
My emmc is loaded with Jessie, so I can easily tell when this happens.
Also, this doesn’t appear to happen on Jessie.
uEnv.txt:
