Booting Beaglebone Black failing



I have just created an account and I am trying to get up and running with a BBB, I successfully added a RPi 3 yesterday but we are changing platforms to the BBB.

I have created an app and downloaded the image from the Add a new device window for the BBB.
I have written it to the SD card using BalenaEtcher but when I load it into the BBB it is throwing an error then reverting to the eMMC.

The card is new and was used for the RPi so is known to be good, Etcher verifies ok. I have tried redownloading the image but I get the same result:

Any ideas where I can go from here?


OK I need to learn to RTFM. When redownloading the image again I read that I have to hold the button to flash it to the eMMC - I had assumed it was booting from the SD card and when seeing the errors just assumed it was an image/write problem.
Held the button on boot and, lo and behold, it has sprung into life.


Glad to know that you made it work.
