sorry to answer this late. iam on vacation. iam owning an l018 and its in the bedroom too but i havent started on that one but things should be pretty similar. i am actually working on getting HDMI to work and requested GPL sources from allwinner.

Updating to include a few more I've successfully run... OpenMW - FOSS Engine to play Morrowind & it's KOTOR total conversion Starwind UFO: Alien Invasion - an XCom "homage" Yamagi Quake 2 - FOSS engine for Quake 2 Mods for Quake & Quake 2 probably work but I shouldn't squeeze any more games on the eMMC for now. If any of you can actually confirm that things like Slayer's Testaments, Brutalist Jam III, Slave Zero X Enyo, Prydon Gate, Dawn of Darkness etc work at a decent stable framerate then I'd appreciate it.

Hello good people. I honestly had given up on that thing, until last weekend, where I set my mind to finally get it to work. And work, it does! eMMC works, display output works without a trouble, and only today I've seen @eloirotava's comment about the 6051. And I'm calling for help again on that one. I currently am using the kernel 7.0.8-meson64 (the current edge for the tv box) and no matter what i'm doing, there's no way for me to get the correct linux-header files, to compile and install that module. May a kind soul help me? I'll post a full documentation very soon, and will probably push my work to the armbian git, once everything is clean. Thank you very much in advance!

I used Balena for the burning process, do I need another complementary program?

@Suly rtl8703bs works with 8723cs driver, but the proprietary driver has been disabled so far in newer kernels because maintenance was becoming more and more complex. Actually I don't remember if it works with the mainline kernel driver. Probably it works, but I don't know if it is enable in rockchip64 kernel; it is surely enabled in rockchip armhf family.
