WiFi does not work with IPv4
Dear Staff
I installed the RockPi 4C with the image (- the 3rd image test): https://dl.radxa.com/rockpi/images/ubuntu/rockpi4c_ubuntu_focal_minimal_arm64_20200820_1207-gpt.img.gz
I can't connect to my RockPi 4C through WiFi IPv4. I got only IPv6 with the new system image but I use in my network IPv4 and I don't want to change this. Also there a lot of driver fails and log spam in the serial console, so it's hard to do anything there.
BTW: I also tested the Android 10 for RockPi 4c https://rock.sh/rockpi4c-android10-gpt-download with my RPI DSI display which working on RPI. The Download description shows 'DSI 480P: Canvas size 480800 Support Raspberry Pi official 7" Display' but the screen leave black and off. In the log through serial console shows some errors in the dw-drm-mipi-dsi layer. Some OF(DTS) properties/phandles not found i.e. 'rockchip,grf'. It seems to be incomplete buggy DTS binding or dw--drm implementation.
I'm frustrated with the HW/OS I bought: I would be very happy about a production-ready 'consumer'-compatible operating system. I finally want to finish my project without operating system development or kernel error analysis. After all, I bought hardware for cash on the assumption, as described on the website, that it works with the connections listed. Of course, this also includes a functioning operating system, as is generally the case.
