T536显示支持情况

T536支持LVDS、MIPI-DSI、LCD三种接口的屏幕。不支持多屏同显异显。

2. 测试方法

2.1. 修改设备树，没有使用切换屏幕的方法。

主要修改

device/config/chips/t536/configs/demo/uboot-2023/uboot-board.dts和

device/config/chips/t536/configs/demo/linux-5.10-origin/board.dts。

使用时将对应的dtsi使能即可

图1.1 device/config/chips/t536/configs/demo/uboot-2023/uboot-board.dts

图1.2 device/config/chips/t536/configs/demo/linux-5.10-origin/board.dts

2.2. 在uboot下切换屏幕

2.2.1. lvds屏幕

显示屏	接口	分辨率	设置项
京东方M101 10.1寸屏	单路LVDS	1280x800	[1] 10.1 inch(1280x800) Beo screen.
群创VI101IA14 10.1寸屏	单路LVDS	1280x800	[2] 10.1 inch(1280x800) Innolux screen.
TI070EI418 7寸屏	单路LVDS	1024x600	[3] 7 inch(1024x600) screen.
THX070S120BS 7寸屏	单路LVDS	1024x600	[3] 7 inch(1024x600) screen.

LVDS显示适配的是群创VI101IA14、京东方M101、THX070S120BS和TI070EI418这四款屏幕。可以通过U-Boot菜单进行选择，在U-Boot启动倒数结束前按下“Ctrl+c”，进入U-Boot设置菜单，根据实际情况选择。

2.2.2. mipi屏幕

显示屏	接口	分辨率	设置项
FRD500H30111-A 5寸屏	MIPI-DSI	720x1280	[1] 5 inch(720x1280) FRD screen.
FRD500H30111-B 5寸屏	MIPI-DSI	720x1280	[2] 5 inch(720x1280) FRD screen.
DM070B30-27-01 7寸屏	MIPI-DSI	1024x600	[3] 7 inch(1024x600) DMGD screen.
VI101GP351 10.1寸屏	MIPI-DSI	800x1280	[4] 10.1 inch(800x1280) screen.
新VI101GP351 10.1寸屏	MIPI-DSI	800x1280	[5] 10.1 inch(800x1280) new screen.

MIPI-DSI显示适配的是FRD500H30111-A，FRD500H30111-B，DM070B30-27-01，新VI101GP351 10.1寸屏和VI101GP351这五款屏幕。可以通过U-Boot菜单进行选择，在U-Boot启动倒数结束前按下“Ctrl+c”，进入U-Boot设置菜单，根据实际情况选择。
