The first attempts to boot were a total failure with the keyboard leds blinking so something was going wrong for sure.
Tried many SD cards until I got the board working.
Surprise : the wifi module is not supported....ok let's use a USB wifi dongle.
After some minutes my RockPro64 was simply disconnecting from the wifi, lagging in the console, and finally freezing.
In theory if you provide a higher Amp, the board should only drain what it needs... but then I tried a 2A power source I had around and all the problems were gone. The board was working as it was sopposed to do, with IPFS running for hours.
I've seen other posts about having problems with 5A.
So... keep your boards down to 3A. My suspicion is that 5A are only needed when you have LCD screen or other power consuming accessories connected.
Sounds like a bad powerbrick it has either not stable 12V at all or a bad barrel connector.
The theory is right and the bord uses only what it needs but some sources are unstable that can crash the board.
