RockPi 4B Experiments

Nitr0 · November 15, 2019, 12:22am

Revised Installation aimed without a script which utilizes dump1090-fa, dump978-fa, skyaware978, piaware & precanned USB GPS support:

Most piaware-config options affecting things other than piaware itself work by generating config files for other packages. This is only done on the piaware sdcard image; if you’ve done a package install, the assumption is that you’re going to configure everything yourself directly.

Nitr0 · November 15, 2019, 5:28am

Yup, old dog, new tricks adage works well here. I came back to a helluva an advancement after a couple year siesta.

Cut me some slack as I’m here to help push the limits again, in hopes some benefit in the process and learn to think outside the box.

Bear with me, as the last thing I worked with in this realm was mutability. You’ve done great, all caught up now for the most part with ya’ll’s help, thank you.

Time for me to go back under the rock I crawled out from I guess.

Thanks for the sharing.

This is tom from the Radxa team. If you have any other questions about ROCK Pi 4B. I can reply here.

Been playing around with the RockPi4, seems to have lots of power to spare.
Does anyone know how to get chip info /processor, etc?
/proc/cpuinfo doesn’t provide the usual Hardware/Revision/Model, but gives the serial, but I can’t figure out how to decode it.
I also see vcgencmd isn’t present, is there some other equiv command for getting voltages? Does throttling even apply on this board?

The RockPi 4 uses a Rockchip RK3399 with 6 cores - 2 big, 4 little.

You might be able to get cpu stats from querying sysfs:

cat /sys/class/thermal/thermal_zone0/temp

should give you cpu temperature.

cat /sys/class/regulator/regulator.7/microvolts

should give you the cpu voltage.

From what I can gather only the 2 big cores are thermally throttled. I have no idea whether it throttles for voltage. You’ll probably have better luck asking in the rock pi forum for more hardware specific stuff.

Nitr0 · April 27, 2020, 2:34am

Please do share if you get it figured out. I’ve been running the RockPi 4 solid since I wrote the initial thread and it’s been running perfect.

This does work, however I haven’t been able to figure out the correct voltage capture method yet. That said, very little time invested trying.

Solid little board this has been thus far. Still running Airspy (24SR, OPTIONS= -v -f 2 -e 9.92 -w 3 -x -t 600) on 1090, RTL-SDR v3 for 978 along with GPS unit all on the same board feeding FA, FR24, Airnav, PF and ADSBExchange no issues whatsoever with MLAT or other hiccups.

Well I found dmidecode, but it doesn’t work on the RockPi.
I found some others, lshw, hwinfo, lscpu, lspci, and the craziest, inxi.
All can be installed with apt-get, inxi has a bunch of requirements (inxi --recommends will show them).

Any local shops in the USA selling the RockPi?

mikkyo · June 21, 2020, 7:36pm

I ordered mine from China. Took a couple weeks.

ca249 · July 31, 2020, 10:32pm

Got a rockpi4B yesterday from Amazon. They have them in stock with two day delivery.

The current image provided by Radxa is now rockpi4-debian-stretch-desktop-arm64-20190730_2022-gpt.img.gz

Using that image and the instructions in post 20 resulted in an “error code 1” message while running
“apt dist-upgrade”. The last few lines are listed below. Any help with resolving this would be appreciated.

BTW how do you put text in the scrolled text box?

Put 3 “backticks” on a line by themselves before and after the text that you want to show as code. -```

looks like this, in practice

It’s the key below the ESC key on most US keyboards - the one with the tilde (~).

abcd567 · July 31, 2020, 11:56pm

@ca249
@jafrank

An alternate to placing 3 backticks ``` above and 3 backticks ``` below the chunk of code, place [code] above and [/code] below the chunk of code.

did you try sudo by chance?

Thanks guys “plus > 20 chars”

Many times.

After booting to the distro image:
changed password
changed hostname
edited /etc/hosts
set timezone
set locale
edited .bashrc
reboot
Then started your commands.
I did not change the governor because I do not have a heatsink/fan yet. This thing runs warm.

I did all this several times with the distro image and also an image that seems to be the same version
you used originally, but it has a slightly different filename. I found it out on a 3rd party mirror site.
I also tried staying with stretch with each image. All these attempts end with ‘error code 1’ from
‘sudo apt dist-upgrade.’

Nitr0 · August 1, 2020, 5:55am

Interesting. I’m out of town, but when I get back after a few days I’ll dig my spare RockPi out with the latest Radxa release and see where it goes and post back. I still have my original (built using the instructions I pasted above) in full production and havent had to touch it since…It’s been as solid as they come using an Airspy R2 on Dump1090-fa, Dump978-fa using and RTL-SDR radio and the USB GPS without issue. Hopefully I can reproduce and we’ll work through it. Impossible to guess without plowing through it myself.

Thanks for the input - so far I couldn’t be happier with this SBC since I know the RPI 4 cant handle the USB throughput that this thing does with dual controllers - but… it takes a little work to get there obviously.

For cooling, I nabbed one of these heatsinks, but not sure if they still sell them:

This is a packaging error (or perhaps an incompatible combination of package repositories); short of waiting for an upstream fix or fixing the packaging yourself, there’s not much that you can do other than try removing one or the other of those packages (libgles2 and libmali-rk-midgard-t86x-r14p0) if they’re not needed on your install.
