Thanks. Sadly I cant/wont do it myself as I dont know anything about linux and dont have another pc to try it. Will wait till someone builds it.
About my device, what do I have to do so I can have wifi and correct device settings like ram timings so you can put it on the project? Right now, thanks to your project, device has a purpose, but I find it incomplete without the remote, wifi, and probably wrong ram speeds.
You may also share the original firmware image if you have one. Sharing just the first 20 megabytes of the firmware would be much better. Don't forget to make a zip/rar/gzip of it.
Remote should already work, you probably need to configure the key bindings: there are some useful posts about configuring rk3228 remotes in the rockchip forum section, but you can also use the procedure for amlogic or any other device.
About the esp8089 wifi, I added support for that in armbian and it works, but I had no chance to test it personally and it is based upon one user experience, so the device tree could be terribly useful for this also.
