Snakeoil 1.4.0 (High End)

Thanks. I'd found that page. And tried substituting the official RPi 5 PSU for my Linear PSU, but no joy 

There is also a YouTube video where the guy shows a way to override the Ubuntu error message on boot supposedly to allow the machine to boot. I haven't tried that, but perhaps I should.

It was a pain to get a power supply that the Pi5 recognises as 5V, 5A. Failed with super duper Gaan USB charger with 65W and Dell laptop 45W charger. Best to attach monitor to see what is happening. It will give you a message to press the power button to temporarily bypass this restriction, and also what to change in config file for permanent bypass.

Was not expecting a SQ difference, but the USB boot is better than microSD!     Brought it back closer to the NUC. So may have to start looking for a new LPS

Interesting about the PSU problems. Have you tried a shorter power lead? I've just remembered as I write this that I had problems with earlier RPis not working satisfactorily with longer power leads. I'll put that on my list of things to try when I have the will to mess about more!

@"hkphantomgtr" using USB C, not GPIO.  And the change was set_max_current_enable=1 in config.txt so that it would boot with 3A power supply.

May look at getting official power supply.

FWIW, the official PSU made no difference for me.
