@magnumsoft, by any chance would you have the firmware for B00-MX3mini-VER1.7 board with 2Gb of RAM?
I have used the ROM shared by you - thanks a lot because you have saved me. But now both the Android TV and the Armbian o.s. just recognize 1GB of RAM. According to what I have researched so far this parameter might be specified at the Android u-boot…
