DISPLAY usage

The Core-186JD4 features an HDMI interface (supports 4K@60fps) and a MIPS DSI interface (maximum output capability of 1440P (2560 * 1440)@60fps,The interface location is shown in the figure 。

It is important to note that, /mnt/system/ko/soph_drm.ko the driver for the entire display framework, such as HDMI and MIPI DSI module drivers, is packaged within this driver.

HDMI

After booting, the Core-186JD4 does not have a built-in desktop environment and only runs a display program:

insmod /mnt/system/ko/soph_drm.ko # 安装显示框架驱动
systemctl stop SophonHDMI.service # 关闭 HDMI 的显示界面
systemctl restart SophonHDMI.service  # 恢复 HDMI 的显示界面

MIPI DSI

Currently, the system can only have one display; when you connect HDMI, the MIPI DSI does not output by default. However, if you unplug the HDMI, the connected MIPI display module will show a test pattern in the form of color bars.

Currently adapted for Firefly's DM-M10R800 V2 display module.
