November 17, 2025Nov 17 Hi all, I would like to ask support for the board EMB-3531. I'm having problem with booting this board from SD card. Here are some informations about this board. I hope that someone can help me with it. Thank you so much! I try to erase the emmc and flash the MiniLoaderAll.bin but it doesn't help. Or i don't have a correct image with armbian for this board. https://my.kos.org.cn:5154/rockchip/EMB3531/emb3531.pdf Edited November 17, 2025Nov 17 by dale
November 26, 2025Nov 26 Author I have a working img that boots fine from sd card. However the dtb is not perfectly working. Below are dts from android and linux (partial working). I hope that someone can help me with rewriting device tree source for it. Thank you! rk3399-emb3531.dts.txtrk3399-emb3531-android.dts.txt Edited November 26, 2025Nov 26 by dale
January 16Jan 16 Author I have a question about booting from sd card. While with empty emmc (erase with rkdeveloptool), the board falls back to maskrom mode even the sd card (with working os) is inserted. It can boot armbian into sd card if I flash miniloader and u-boot in to emmc. I wonder how can we get it to boot fully from sd card.
