I have some spare laptop chargers with 19v output, if I just use DC to USB-C adapter will it work with rock5? The board can do 20V maximum, but 19V is not defined in USB PD so I’m not sure if it would damage the board.
Rock5 does not work on most PD power supplies
no 1v down is no problem it runs also with 5v but i would highly recomend a active adaptor with a stepdown convertor
I just updated loader and it seems to help with PD negotiation, I was curious if they already shipped with right loader or not, so it’s old with those pd problems. Diff on console shows:
DDR Version V1.07 20220412
new one: DDR Version V1.08 20220617
Now it boots with nvme connected on same PD charger, but still no nvme drive detected on system.
You are correct about discord, I don’t like it too, but more and more people are using it. Some claim that it’s just new IRC. This may be true, but it’s still problematic and there should be some copy somewhere else.
please upload a picture of the m.2 ssd without the rock 5b
I already confirmed that some nvme is working on my rock5 (on pd), I’ll start new thread about this.
could you post a link to this new thread
But not all M.2 SSDs are NVME some M.2 SSD are SATA and some are even USB(rare).
So maybe the hint was into that direction… Though slot keying should usually prevent incompatible pairings, they can still occur.
thats why i asked for a photo
if this page is accurate… but well it is not that accurate, like the PMIC is RK806 but it says RK809, typo?
the charging IC is IP2315, which takes input up to 12V; searching online I saw it as capable of taking 12V4A, so it kinda explains why PD negotiation only stop at 12V?
Only stop at 12V is a pure software problem because Radxa hardcoded to only stop at 12V. A new kernel is released recently with support up to 20V.
interesting, when I check IP2315 datasheet it says 5-15V, but at the company website it says 5-30V 
it is often so wierd most of the times both are right but in a different way
So all of my PD charges are negotiating to a lower amperage than expected and nVME won’t boot. What’s the easiest way to provide clean 12v power to the usb-c port? Trying to figure out a way to use an atx PSU
here’s an example:

12v you just wire up to a usb-c connector and go. It has a buck that can cope with 20v but apparently ancillary components are much lower about 13v but its happy running on no pd 12v.
A few are using 12v barrel psu’s with a usb-c barrel adapter and even a usb-c breakout module from aliexpress with just vcc/gnd soldered to a molex or sata power 12v.
I had problems with PD with the v1.3v board and still not sure what happens but using a Pi5v usb-c works and after a couple of restarts plugging back in my PD magically works.
I didn’t seem to have a problem with a nvme Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM961/PM961/SM963
Maybe old/budget is the way to go as its still only entry level desktop class.
I have a similar problem: most of my power supplies did not work and I am currently using a Framework laptop PD power supply, but when I install a desktop environment or connect it to HDMI, it will stop working and only power cycles. Same with a SSD (currently booting from µSD)
I already updated the OS (rock-5b-ubuntu-focal-server-arm64-20220919-0839) after installing, but the problem remains.
What can I do, and what (EU) power supply is guaranteed to work?
it looks like it is only negotiating 9000 mV, 3000 mA
can I fix this in software?

that is plenty of power for the rock 5b if you dont hook up power hungry devices
one possibility, but I didn’t try myself on Rock 5, is to use a PD to DC cable, and they should not be expensive (around US$2 in China); you may get a 12V or 15V + DC2USBC adapter, and that would be sufficient. I use quite a few of these PD cables (mainly 9V and 12V) for a lot of my devices (routers etc)
yes that would be helpfull but put a big red label on it so no one plugs it in to a phone or a pi
