Hello, I just want to inform to anyone that still is going with this project that from here https://www.terra-master.com/code/ you can download the sources of openwrt for rtd1295 (i believe they are complete, with kernel and bootloader sources, and ffmpeg encoder), i found it because i have a wd nas with this chip, and i was trying to bring the video transcode to linux, i failed because my knowledge is limited, but maybe is useful to bring armbian to this board.
