A curious problem just happened to me : I own a Bela I didn't use yet and just tried to boot it.
After a while, it appears on my computer's desktop as "Beaglebone" instead "Belaboot".
Of course, it's not recognized by the IDE.
I tried to insert the microSD card in another Bela and Bela Mini and it was ok so, it seems to be a hardware troubleshooting.
Any idea ??
