I made a few adjustments to the device tree for my XT-RX4B-V02 based box. The intermediate results look promising:
wifi (RTL8723CS) basically works
memory perf:
armbian@rk3328:~$ dd if=/dev/zero of=/tmp/testfile bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 1.70386 s, 615 MB/s
... this was within an x11vnc session, on multiple tests I constantly get values greater than 550MB/s (The board has 4GB DDR3/1600 ram)
Notes
I never experienced stability issues. As the mounted "heatsink" is more than dubious, I lowered the temp limits just to stay on the safe side. Scaling down the cpu-frequency on temp limit works flawlessly.
The voltage settings used in Android are slightly lower than the ones in use. I had no time to test, might improve temps a bit.
There are still a number of issues, maybe someone around could kick in?
Wifi client: Connect using nmtui is fine, but how to auto-connect on system start?
The adapter chooses a random mac on boot. I think assigning a static one would help - I just did not find a proper way of doing so...
dmesg tells me that there are still a number of device tree issues that might prevent the gpu from working properly.
Bluetooth (RTL8723CS) does not work yet (while usb bluetooth dongle is fine). I got the impression (might be wrong) that chip support will still take some time, but I'd like to get the device tree right and don't know how to prove that I got pins/uart/device tree settings right.
@balbes150 lsmod tells me 8723cs and 8723ds get loaded. Removing 8723ds.ko helps - what would be the right way of dealing with such situation?
@mb16 Hi! I recently got a Leelbox Q4 Plus, which is very similar to yours (same board 'XT-RX4B-V02' and wifi 'RTL8723CS'... but has 64gb of storage). I wanted to ask if this is still your most up-to-date DTB file?
@balbes150 Thanks for all the hard work man! Given the above info, what DTB would you suggest would be best to use on this box? I've gone through all of the included ones and most of them at least boot and work to some degree... wasn't sure how to tell which would be best. The A5X and MX10 ones seem the most stable as far as I can tell, but I wanted to get your thoughts since you know the hardware and modules the DTB files better than I do.
