2. Screen module

2.1. DM-M10R800 V2 MIPI module

2.1.1. Product parameters

  • model: M101014_BE45_A1

  • size: 10.1 inch

  • resolution: 800x1280

  • display interface: MIPI

  • visual Angle: 160°

  • touch screen: multi-point capacitive touch

2.1.2. Refer to the firmware

The official MIPI firmware default support MIPI_DSI1+HDMI display, MIPI screen connected to AIO-3568J MIPI_DSI1 interface. Below is the link to the firmware: Firmware link

NOTE: When using HDMI display, there may be black edges on both sides of HDMI. The reason is HDMI as a secondary screen, will be scaled according to the aspect ratio of the main screen MIPI. If the aspect ratio of the two is inconsistent, it will lead to black edges.

2.1.3. Compile command MIPI_DSI1 + HDMI

Using official SDK to compile firmware that support 10.1 inches screen firmware need the following command, the default compiled firmware is MIPI_DSI1+HDMI display + CAM-2MS2M camera:

./FFTools/make.sh -d rk3568-firefly-aioj-ipc-mipi_M101014_BE45_A1 -j8 -l rk3568_firefly_aioj_ipc-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3568_firefly_aioj_ipc-userdebug MIPI_DSI0 + HDMI

If you need to use MIPI_DSI0 or MIPI_DSI1, you can refer to kernel/arch/arm64/boot/dts/rockchip/rk3568-firefly-aioj-mipi101_M101014_BE45_A1.dts. By default, it supports MIPI_DSI0 + HDMI + CAM-8MS1M camera module. The compilation command is:

./FFTools/make.sh -d rk3568-firefly-aioj-mipi101_M101014_BE45_A1 -j8 -l rk3568_firefly_aioj_mipi-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3568_firefly_aioj_mipi-userdebug

Note:If need to use CAM-2MS2M camera,first to add patch。
