Dear Friends,
I have an EDM-010 board with no UART connectivity, and it appears someone has previously attempted a repair. All standby voltages seem okay, but when I checked for a Vcore short, I noticed a very low impedance of 0.2 ohm
After removing the 12 inductors, I injected 1V using a 5A power supply. Initially, the voltage dropped to 0.6V. I then increased the voltage on the supply until it reached 1V, at which point the current draw rose to 3.5A. Is this behavior normal?
Thank you
