Hello Folks, good day. I have a project where I need to use a OrangePi 4B and couple of hardware pieces connected to it. I'm having trouble putting together a Linux image where I have, at least the minimum functions required for the project working. I need an image where these items below are enable/working: - SPI - I2C - GPIO - PWM - 10.1 MIPI DSI LCD + TOUCH (available here) - MIPI CSI Webcam (OV13850) - 3D Acceleration (WebGL / OpenGl) using the Mali t860 - Bluetooth - Wifi Ideally, I would like to use the most recent Focal mainline kernel, but a legacy image will also be fine. I've been spending a lot of time building and testing many different images, I tested all available on the OrangePi website and the ones pre built on the Armbian too. Some peripheral works on some images, some others not, etc. I also built several images myself but, up to the moment I was not able to make a single one with all the features above working. I'm looking for help from the experts here on suggestions/guidance on how to accomplish the task of having a single, (preferably updated) linux image working on this project. Appreciate the help. Thank you.

Hello Folks, Good day. I hope you're doing great. I'm trying to make the OrangePI 10.1 inch MIPI DSI (product page) work on the most recent (mainline) Armbian build. Building the image using the OrangePI source repositories and following the instructions on OPi4B manual enables the LCD and touch, However, my intention is to make the LCD + Touch work on the most recent Armbian Focal (mainline). I've setup my Armbian build env but I cannot see to find how to enable this MIPI screen on any build options. Here's the instructions from Page #20 of OPi 4B manual: Download the Linux source code and make the following changes in dts --- a/arch/arm64/boot/dts/rockchip/rk3399-orangepi-lcd.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-orangepi-lcd.dtsi @@ -40,12 +40,12 @@ max-x = <800>; max-y = <1280>; tp-size = <101>; // <911> for 8 inch // <101> for 10 inch - status = "disable"; + status = "okay"; }; }; &dsi { - status = "disable"; + status = "okay"; panel@1 { compatible = "simple-panel-dsi"; reg = <0>; That specific file doesn't exist on the Armbian build directory tree. I'm not familiar enough with the dts and dtsi files to be integrating it. I've been searching the forum for answers but, so far, I'm not able to make it work. I'm looking for help on enable it and appreciate any pointers or guidance that can help make the LCD + Touch work on a mainline kernel version. I linked some dts files from the OrangePI source repository that "might" help. I'm thankful for any help. Thank you.
