I tried several Apple laptop chargers and no luck (also using Apple cable): 29W, 87W and 96W. Those chargers work fine with Rock 3A and SSD. Rock 5b is without SSD.
I will try something else and see if I can get it to start.
Thanks for the suggestion.

If you’re using sd card, I recommand you to use emmc instead.

@amazingfate I do not have an eMMC card.
It seems that the apple non-pd 12W got the board running. Thx for the suggestion @stuartiannaylor

Yeah I don’t have a emmc card either I presume I would of run apt-get upgrade whilst testing and an update fixed things as now this pd works fine, but I was the same with a boot loop.
You can flash the image into emmc module from a linux/mac computer, here is the step: Nvme software support at launch of rock 5b
Mainline support is going to be a catastrophe with anyone using real PD supplies getting infinite boot loops.
If FUSB302 on mainline is a problem, then we should somehow fix the mainline, right? We do think these kind of smart power design is way better than than fixed one.

I think PD is great for mobile battery devices/tablets/laptops where charging might take place on multiple devices.
I am a bit mweh when it comes to PD as generally when a SBC is in place so the PSU is of fixed use and not often shared elsewhere as you lose power to the SBC.
The 5.148V - 26V buck is a great piece of silicon https://www.monolithicpower.com/en/mp8759.html as does a quite a good job of an extended efficiency vs volts/ampage curve. That is the star of the show than some negotiated multi-rail PD.
So far a cheap 5.5mm barrel to USB-C still makes a fixed 12v much more cost effective than any equivalent PD and after negotiation at a fixed volt I still fail to see any advantage of PD.
If you can reclaim the x2 CPU cooler mount holes and then have room for a 5.5mm DC jack plug then please do as that then releases the USB-C to be a USB-C.

And there’s the reason:
Maybe someone can find a better solution, but when I wrote the code I just
could not get it to work reliably without resetting everything during
registration.
Since FUSB302 appears on all new RK boards these days (since being part of the reference design and as such copy&pasted) a fix in mainline will be needed. It might help pinging those at Rockchip dedicated to such stuff [1] early since everything that happens upstream usually takes ages.

There are a lot of commits in mainline kernel after rockchip’s 5.10 vendor kernel: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/drivers/usb/typec/tcpm/tcpm.c?h=v5.18.12. I guess this commit is related: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/usb/typec/tcpm/tcpm.c?h=v5.18.12&id=90b8aa9f5b09edae6928c0561f933fec9f7a9987.
This issue is reported in 2020 on board ROC-RK3399-PC. I don’t know if this board still have this issue in 2022 using mainline kernel 5.18. Can anyone who has this board confirm that?
I have the board, the issue persists.
BTW: RK’s BSP kernel provides some more info about what FUSB302 is doing:

Yeah I don’t wanna trigger anybody here, but just made interesting discovery in a Rock 4 chat on Discord
TLDR;
User has Rock pi 4B+
- RTC clock has battery.
- when using USB-PD to power, depower and power again… the RTC clock resets
- when using dumb 5V, the RTC clock value persists over power cycling
This is all speculation, but generally speaking… I think these IC’s oriented around USB-PD and SoCs, kernel code whatever-- are oriented around platforms that are battery first aka usually some persistent power to the PMIC from a lipo and charge controller etc, vs these things are getting full de-energized and having to dance.
So we’re fighting an anti-pattern.

I think this might be a noise transient issue for the Rock Pi 4 family. If the schematic is accurate, it uses a single 16V capacitor for input voltage filtering. PD will negotiate 20V (mine does) and will damage that capacitor. Over time I suspect any power line transients will go straight through the buck converter and cause unpredictable disturbances to the attached hardware.
Sorry for /offtopic

Journalctl always shows the same if pd or dumb.

Will the production rock 5 get a jumper or a proper button for maskrom instead of that cellophane button. (Personally I prefer jumper)
2 Likes
Yeah please after my Radxa Zero disaster of the cellophane part detaching it would be good.
Also the onboard buttons for power and restore as they are perfectly ok but jumpers might even be cheaper but allow you to have wired switches instead or even relays (as on a PC mobo).
That leaves dsi/csi/gpio/hdmi-in to maybe have a bottom mount bracket with extension cables/risers and all i/o could be on a single plane which apart from needing a cutout would be fairly easy to fit in any enclosure bigger than the approx 100x72mm of the Rock5b.
Guess it could be top mount if you have a blower than axial fan as a gpio riser would prob choke otherwise.
Purely as an extra in the shop but it would be an auto buy for me at least.

I think most of the time, you can just use the loader/recovery button, which is next to the power button. Maskrom button should be seldom used since the bootloader corruption is not often.
2 Likes
Sadly maskrom is easier. There’s a lot of software orchestration typically to use the loader / recovery button.
For people on this debug thread It’s always simpler to write an entire image.
So I had more time to test mine.
First I had a problem that appears specific to my board: it will randomly reboot. It does not seem related to overheating, CPU load (idle will also reboot), or power supply issues.
Networking and storage are both great on the board, but I had the following issues:
- Only the HDMI port next to the USB ports works. The other HDMI output port does not work, and neither USB-C DisplayPort alt mode (my USB dock is not supported either, see below)
- 3D GPU acceleration not supported, it’s using llvmpipe software rendering
- VPU not tested hardware video playback, as I’m not sure which program to use if any.
- NPU driver spew several errors. I’ve not tested it because the documentation is not clear.
- USB Type-C port does not seem to work properly with a MINIX USB-C dock with a 480GB SSD. It’s detected but emits errors such as “usb usb10-port1: Cannot enable. Maybe the USB cable is bad?”, and the SSD does not show up at all.
- Bluetooth is not working out of the box
