I’m still trying to get a Rock 5B to boot from NVMe. By all appearances they included a USB Type-C port that doesn’t work, so the system never pulls sufficient power not to boot loop. Apparently even after a firmware update.

To be totally fair to the up-and-coming boards, the Pi was pretty poorly supported on day 1 and the community did (and still does) a lot of heavy lifting. I’m still waiting for a contender, but I don’t have the time or energy to devote to another SBC.

Despite being a super prolific maintainer of Pi-stuff and related projects I haven’t had a single SBC manufacturer reach out to me and say “hey what do you need to support this?” They just don’t seem to care beyond shoving product out the door and hoping for the best.

If You have not tried what the other reply-post suggests (dumb brick), I have a 5V 4A dumb brick I can loan for a quick test. Seattle area. It has worked on quite a few boards here. Or purchase one from where-ever, they are really useful outside of SBCs (though they are usually 5.3V and 4.xA, so watch out with sensitive parts).

What is a dumb brick?

[wildzzz]

Sounds like a USB power supply that doesn't do any power negotiation and just gives as much current over 5V as it can handle. Those things typically top out at 2.4A so not really sure where you'd get one that could do much more.

4A, in my measurements.

It is a power supply that if intelligent negotiations fail, falls back to providing 5V (at whatever current), usually (2023) USB-C.

You need to get a dumb brick for that Rock 5B. Looks like you got one of the ones with a bad firmware. When it negotiates the power drops out. There're tons of forum posts.

You are correct. I have many that do 5V 4A.
