Hello.

Flashed the device with latest bootloader and firmware with no problems.
It boots but no leds, and none of the buttons are working except RESET and Encoder push.
Encoder works fine.
What can cause the problem ?

I've changed the MCU to another one.
Reflashed it. Didn't help.
Also, I have a leakage of 590ohm from 3.3V to ground through each of the 3.3V regulators.
I've desoldered the regulator and measured between output to GND.
590ohm resistance, too low !!!
