So I have a dragonBoard with which I have been playing around. I had used it a few days back and it was working fine. However, when I connected it again today it didn’t power up. Upon probing I found out that the 5V buck converter is shorted. I have no idea how it happened and I would really appreciate if you could provide me with possibilities as to what might be going wrong so that I can avoid it. I am using the LM2596 module for the external power conversion(5V to 12V) and I am giving it input using a 5V adapter.
