Hi there, just created an account to say thanks ! I randomly bought a clearance media player on tuesday thinking "there must be something I can do with this and need a project"

A bit of DuckDuckgoing later and found this forum, and well, it's all been done! Good work guys, this device has nand flash and rk3228a so after a few nand reflashes and general messing about etc I decided to flash the latest image to SD card and well, it runs really well.
As previously noted this board has horrible thermal design so active cooling is basically mandatory - anyone experiencing "freezes" or crashes during system updates, note the board temp, it heats rapidly and appears to thermal shutdown at around 80 degrees C.
Have since added a USB wifi dongle which works fine as the onboard wifi isn't driver compat (as previously noted)
So this board appears to have comparable performance to a Raspberry Pi 2b, so as long as you temper your expectations this is a fun system to mess around with.
Thanks !
