We still only ship v2019.04 for beagleboard.org , for u-boot after that point you lose ethernet with the classic “board” method. I’d like to move to a later version, but still need to do a ton of testing on every BeagleBoard variant to fully support the latest u-boot release (which utilize a built-in device-tree).
Hold the “boot” button with your finger nail, insert power, once 1 LED turns on, you can release your finger nail… In that mode, it’ll boot off microSD… If your finger can’t handle it, that same i/o is on the header, just run a quick wire and gnd the pin. (it’s in the BeagleBoard SRM)
