I used Windows 11, a VM, created a snapshot, installed driver (needs admin) used the tool (admin too, super wonky) and rolled the snapshot back, the VM runs on the same Linux box that failed to do the job with the linux CLI tool.
I could not get it working even with fixing the device permissions @xtract I guess there is something else going on there.
Rock5 does not work on most PD power supplies
I also manage to flash now using Ubuntu, and the solution is VERY STUPID: I used the very cheap USB-A 2.0 to USB-C cable, and donāt use anything in between. Then I just follow the official guide and everything seems fine. I used USB-A 3.0 to USB-C cable before (swapped from my USB HDD) and that wonāt work. Having USB-C extension cable also wonāt work.

Ohh well, I can confirm, works fine with a USB 2.0 USB AtoC cable, not working with C to C and also not with a 3.0 A to Cā¦ like what the fuck?
it is really stupidā¦ I just found that out by opening two ssh sessions and monitor on whatās happening on the host side using dmesg -w, and see a lot of usb related messages that should be weird until I used that USB-A 2.0 to USB-C cable, then the usb message become ānormalā.
@jack may I get a v1.3 dev board for finding this out? hahaha 
With rock-5b-ubuntu-focal-server-arm64-20220930-1451-gpt.img all my problematic USB PD chargers work now and the SPI flash is accessible from inside the running OS since this little device-tree snippet is active:

They are advertising this at 12v, 15v, 20v. Is the problem being discussed affecting the 5B 1.42.2022.08.29 ?
Also unclear but is it a software / firmware problem, or hardware? Iāve got a 5V, 9V, 12V, 15V, 18V, 20V usb-c 65W adapter coming tomorrow; hoping to stick an NVMe in with wifi.
Iāve also stuck passive coolers on the RAM and will put something 25mm x 25mm x 24-50mm on the die with adhesive or a movable pad.
I guess, judging by the bootloader code, the Rock5B only accepts up to 12V.
Advertising was not the point hereā¦ At least not so far.
Here is the link Iām referencing. It might be a translation issue

So long as it negotiates and doesnāt burn itself out I donāt mind. Just seems a strange communication glitch. Excited to see how bloated I can go with 16GB RAM 
please be so kind to explain: is this version updating the SPI from the OS or is the OS doing the neg? just got the package today (btw. if someones in germany an desperately waiting for one: i have a spare 8gb version, that i can lend out for the duration of my parental leave/āno tinkering timeā) and want a fast start tomorrow. else iāll just update the bootloader
well that might take ages to mergeā¦ but yeah, good to know.
Have You tried with nvme? On my side with m.2 it hangs and are not able to run. Iāll give a try latest image and more chargers but so far I was not able to run with nvme (few different).
Has been merged 20 hours ago but not arrived in Radxaās package repository. I updated their Ubuntu Focal image right now and after a reboot still no USB PD negotiations exceeding 12000 mV.
Nope, still only crappy SSDs lying around here.
Mine boots fine without anything in m.2 -
I think it booted once, but drive was not found in system.
As far as I understand itās safe to supply something like 12V 4A to usb-c (without usb-pd)?
If I understood it correctly then the way Radxa is doing this USB PD stuff currently is still flawed. They enabled lower DRAM clocks to
āhave enough power booting to kernel PD voltage negotiationā
Yes.
For now with nvme I have bootloop:

Itās with nvme connected and latest radxa images on sd or emmc card. Is there anything that I should update (firmware, bootloader?). Itās before system is loaded so Iām not sure if anything from sd card make any changes.
Ask Radxa. Iāve never seen such a stupid board bring-up process like here where early adopters / testers were encouraged to send feedback in a closed Discord channel lacking any public log (as such everything babbled there is lost) while reacting to community questions/suggestions neither here in the forums nor over at Github (1st example, 2nd example introducing stability/reliability issues on a number of boards equipped with āweakā RK3588).
try it without any emmc or sd and compare the log if its th same update the firmware in the spi rom
