RK3288 增加双屏异显 eDP+LVDS
CPU：RK3288
系统：Android 5.1
下面是官方文档中的信息。
1、rk3288 支持的显示接口可以任意组合。
2、双屏异显时，一个显示接口当主屏，另一个当副屏；主副屏由板级 dts 文件确定，启动后无法动态更改。
3、当两路显示接口显示不同分辨率时，rk3288 只能为一路显示接口提供精确时钟，另一路显示接口时钟会有微小频偏。
瑞芯微虽然提供了 Android 5.1 的补丁，但是本人在移植过程中出现一些问题（打补丁最好一行行核对，不要图方便直接使用指令）。
设备 eDP 为主屏，lvds 为副屏。
（1）首先修改两个屏参文件 lcd-xxx.dtsi。
eDP 屏参文件补丁

（5）官方提供的补丁打完了，但是此时编译可能会报错，如下：

根据编译错误提示，需要修改 cts/tests/tests/view/src/android/view/cts/WindowTest.java 文件。
diff --git a/cts/tests/tests/view/src/android/view/cts/WindowTest.java b/cts/tests/tests/view/src/android/view/cts/WindowTest.java index 3c5386d..8732ae7 100755 --- a/cts/tests/tests/view/src/android/view/cts/WindowTest.java +++ b/cts/tests/tests/view/src/android/view/cts/WindowTest.java @@ -998,6 +998,19 @@ public class WindowTest extends ActivityInstrumentationTestCase2<WindowCtsActivi } @Override + public void moveAppToDisplay(int id) { + } + + @Override + public void syncDualDisplay() { + } + + @Override + public void moveExtendDisplay() { + } + + + @Override public void setDefaultWindowFormat(int format) { super.setDefaultWindowFormat(format); }
（6）此时可以编译成功，在屏参正确的前提下，主屏显示正常，副屏出现花屏，需要在 system.prop 里添加属性 ro.htg.force=1。
diff --git a/device/rockchip/rk3288/system.prop b/device/rockchip/rk3288/system.prop index 26a2b09..c4f2c3d 100755 --- a/device/rockchip/rk3288/system.prop +++ b/device/rockchip/rk3288/system.prop @@ -12,6 +12,7 @@ rild.libpath=/system/lib/libril-rk29-dataonly.so rild.libargs=-d /dev/ttyACM0 persist.tegra.nvmmlite = 1 ro.audio.monitorOrientation=true +ro.htg.force=1 #NFC debug.nfc.fw_download=false
此时大功告成，双屏可以正常显示，也可以实现双屏异显。
如果 lcd 出现重复性黑屏亮屏，找到对应的屏参文件，在正常范围内调节频率 clk 值即可。
display-timings { native-mode = <&ee101ia>; ee101ia: timing0 { screen-type = <SCREEN_DUAL_LVDS>; lvds-format = <LVDS_8BIT_1>; out-face = <OUT_P888>; color-mode = <COLOR_RGB>; // 调节 lcd 频率 clock-frequency = <148500000>; hactive = <1920>; vactive = <1080>;
如果单屏调试都正常点亮，打补丁后，点不亮或者有花屏现象，尝试增大对应屏的电源使能延时
lcd_en { rockchip,power_type = <GPIO>; gpios = <&gpio7 GPIO_A5 GPIO_ACTIVE_HIGH>; - rockchip,delay = <10>; + rockchip,delay = <100>; };
