Hello, I'm from China. I can't speak English. I can only translate with the help of translation software. I hope you can understand my description. I have worked hard to come to this forum and search for you. I bought tx3 Mini 2G / 16g at 120RMB in China. I started armbian from USB flash drive and used my own meson-gxl-s905w-tx3-mini.dtb, but memory usage: only 833mb. Can you provide me. DTB file and corresponding armbian system! Thank you very much.
