<Armbian-Discord> <T​enkawa> @IgorPec do you know if anyone has experimented with pushing the pine RK3399 PD more than 5V?
<Armbian-Discord> <T​enkawa> (or anyone)
<Armbian-Discord> <T​enkawa> specificly on a PBP.. I'm curious if it can be done with their usb-c they use or not safely
<Armbian-Discord> <M​icroLinux (Salva)> I do like rockchips, but we are on a different era @IgorPec . If a soc targets chromebooks as today, it has to support mainline on day 1. Also, at rk3355 prices, x86_64 is far better alternative without mainline support.
<Armbian-Discord> <M​icroLinux (Salva)> That's fixed 5v, there is no push beyond 5v thing, unless you are willing to cook your pbp 😋
<Armbian-Discord> <M​icroLinux (Salva)> I thought rk3588 would be a lot cheaper at first, and then it would make sense at least from price point.
<Armbian-Discord> <I​gorPec> no, don't know
<Armbian-Discord> <T​enkawa> oh well.... at least the 3588 likes being pushed... guess I'll just let the 3399 move along slowly
<Armbian-Discord> <T​heBug> I don't know about the PBP but on the RockPro64 they use a 12v barrel jack input, so I would assume it would really come down to the power management on that board supporting it. Schematic may be a good place to look... or pry at @Tonymac32 and see if he has checked that before / knows anything about the power solution there..
<Armbian-Discord> <W​erner> I think pbp has optional 12v PSU but can be powered and loaded via USB-C too
<Armbian-Discord> <W​erner> @NicoD can tell
<Armbian-Discord> <T​enkawa> I'm powering it from usb-c now... but 5V... thats why I was asking about PD voltage limits
<Armbian-Discord> <T​enkawa> I know some of the newer units can run higher voltages however I wasn't as confident this one could
<Armbian-Discord> <T​enkawa> the RK3399 might be too old of a SoC
<Armbian-Discord> <N​icoD> My PBP is only 5V.
<Armbian-Discord> <T​enkawa> Only one I found was this one and it appears to be for Rock units
<Armbian-Discord> <T​enkawa> Every PBP reference I've found is 5v
<Armbian-Discord> <T​enkawa> Oh well
<Armbian-Discord> <T​enkawa> It seems to be recharging it decently fast with this battery (Was trying to add some faster active charging while running... but at least its incrasing as its plugged in)
<Armbian-Discord> <N​icoD> It's a problem certainly when using NVMe. Can only charge at 2.2A while it can consume 2.5A with NVMe. So it's draining while in use. I removed the NVMe and it doesn't consume that much anymore. NVMe drives can be 1A. I'm happy with eMMC.
<Armbian-Discord> <T​enkawa> I know but I really like this NVMe speed hehehe
<Armbian-Discord> <N​icoD> There are nvme drives that consume a lot less. No idea if performance is still as good then.
<Armbian-Discord> <T​enkawa> hmm let me see what mine is using
<Armbian-Discord> <T​enkawa> I am using a high end drive
<Armbian-Discord> <T​enkawa> I could put one of my more consumer ones on
<Armbian-Discord> <T​enkawa> I know this soc isnt pushing it
<Armbian-Discord> <N​icoD> I can't find good info about power consumption on NVMe. Would be nice if anyone would compare them. If you don't need swap files then eMMC performs well enough. I've got a 128GB eMMC module in it. Consumes a lot less and still performs well. NVMe with RK3399 is great. But for me with PBP it isn't a good choice. I was using Samsung EVO 970. Consumes way too much.
<Armbian-Discord> <T​enkawa> I don't even have an emmc in here right now... just using a microsd to chainload
<Armbian-Discord> <T​enkawa> I get a feeling this guy: WD_BLACK_SN750.. is a power drain
<Armbian-Discord> <T​enkawa> its my nvme
<Armbian-Discord> <N​icoD> The sd reader does perform very badly. It can perform a lot better with a USB3 sd-reader. But no idea if it boots from usb. It might tho.
<Armbian-Discord> <T​enkawa> yeah it does with tow-boot
<Armbian-Discord> <T​enkawa> I use that as my backup/recovery media if I oops something in an update/test
<Armbian-Discord> <T​enkawa> Ok the Blue's definitely use a bit less power... nominal though so I don't think I'm going to bother
<Armbian-Discord> <M​icroLinux (Salva)> Rockpro64 has the sd voltage regulat to enable SDHC, so probably the PBP also has it.. it's just not enabled on the dtb, you can also try to add it on your own.
<Armbian-Discord> <M​icroLinux (Salva)> Pbp should have been made at fixed 12v
