giuliomoro Thanks for answering!
Nothing out of ordinary. It is part of my guitar fx rig. So basically, the guitar signal flows through few guitar pedals before going to bela's audion in and from audio in to one more pedal before to guitar amp. There is a powerbank powering bela, it's only for bela and the rest of the pedals has a different bank. I basically have had it with this set up almost daily, since the last three years.
Seems like the only led which is lighting up in the beaglebone mini is the power led. Is there anyway to recover it or try something? I am professionally little bit dependent on it, so I would need to order one soon if I need to replace it.
