Thank you for your answer ,this clarifies a lot , I'll wait for a rk3188 version then .

Hi Balbes150 , I downloaded and burned both images focal and bulseye to SD ( armbian-focal-rk3188_20200629.img and armbian-bulsey-rk3188_20200629_5.6.6.img )and tried them on my MK802IV but they didn't boot to desktop . I did change the uEnv.txt file in the Boot directory to use the radxarock dtb file ,you did not mention that , but it made no difference. I also noted some boot-z img files in the yandex archive ( boot-z-rock.img ) , are they needed in some way? radxarock images usually boot on the mk802IV also. Some elementary booting did happen ,because android from Nand didn't start ,but my HDMI monitor stayed black , there was no signal.

Hello balbes150 , I do have a rkm802IV ( the 'old' model )stick , I can boot the old linuxium linux image from sd , (from this post http://www.linuxium.com.au/how-tos/tastytreats ) . Because it's almost 10 years ago my memory of what I read and did has become a bit rusty so I downloaded this image again and burned it to sd using balenaEtcher on Debian and indeed it booted immediately. I tried a few of your 32 images the same way ,burned them to sd but they won't boot . ( Armbian_20.05.6_Arm-32_focal_current_5.4.43_desktop_20200604.img and Armbian_20.05.6_Arm-32_focal_current_5.7.2_desktop_20200613.img ) ,the system boots to android nand .Then I tried to flash the bootloader from your link using rkAndroidtool under windows 10 ,but that was refused by the program .(check chip not ok) , well .it's a rk3188 so it refuses a rk3288 loader . In the past I read a lot of linuxium's posts and he had many solutions for booting . Not all these posts exist anymore , google+ has dissappeared so it's a bit tricky finding everything back .The next few days I'll try to refresh my knowledge .(I don't know what happened here but i've gone Italic !!)

for wifi I found this https://github.com/wonview/wifi_driver. It might work.I've not tested this myself,in fact it's been a long time since a compiled kernels or modules,before the DTS era actually.
