Firefly-RK3288 开发板 Android5.1 支持7.85寸液晶屏模组的修改方法
本帖最后由 wico 于 2016-12-1 14:41 编辑
一.硬件条件需要对应的硬件支持:
1.Firefly-RK3288 开发板;
2.Firefly-RK3288开发板对应的7.85寸液晶屏模组:
二.软件配置:
1.首先下载更新RK3288 Android5.1 SDK,最新提交:
commit:3e3038c
Message:Android->framework:fix btn default color
复制代码
2.软件修改配置:
1)打开kernel/arch/arm/boot/dts/firefly-rk3288.dts,修改如下:
包含lcd的dtsi:
-#include "lcd-box.dtsi"
+#include "lcd-LP079Qx1.dtsi"
复制代码
关闭vga:
vga_ddc@50 {
compatible = "firefly,vga_ddc";
reg = <0x50>;
gpio-pwn = <&gpio0 GPIO_C1 GPIO_ACTIVE_HIGH>;
rockchip,source = <0>; //0: LCDC0; 1: LCDC1
rockchip,prop = <PRMRY>;//<EXTEND>
- status = "okay";
+ status = "disabled";
};
复制代码
使能tp
mt@40 {
- status = "disabled";
+ status = "okay";
compatible = "firefly,gsl3680";
reg = <0x40>;
touch-gpio = <&gpio5 GPIO_B0 IRQ_TYPE_EDGE_RISING>;
reset-gpio = <&gpio7 GPIO_B1 GPIO_ACTIVE_LOW>;
max-y = <2048>;
max-x = <1536>;
flip-x = <1>;
flip-y = <1>;
swap-xy = <0>;
};
复制代码
使能mpu6050
mpu6050:mpu@68{
- status = "disabled";
+ status = "okay";
compatible = "mpu6050";
reg = <0x68>;
mpu-int_config = <0x10>;
复制代码
修改timing配置和添加屏使能脚:
&disp_timings {
- native-mode = <&timing1>;
+ native-mode = <&timing0>;
};
&rk_screen {
@@ -611,6 +611,29 @@
status = "okay";
rockchip,iommu-enabled = <1>;
rockchip,prop = <PRMRY>;
+ power_ctr: power_ctr {
+ rockchip,debug = <1>;
+
+ lcd_en:lcd_en {
+ rockchip,power_type = <GPIO>;
+ gpios = <&gpio0 GPIO_B5 GPIO_ACTIVE_HIGH>;
+ rockchip,delay = <10>;
+ };
+
+ /*
+ lcd_cs:lcd_cs {
+ rockchip,power_type = <GPIO>;
+ gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
+ rockchip,delay = <10>;
+ };
+ lcd_rst:lcd_rst {
+ rockchip,power_type = <GPIO>;
+ gpios = <&gpio5 GPIO_C1 GPIO_ACTIVE_LOW>;
+ rockchip,delay = <0>;
+ };
+ */
+};
+
};
复制代码
使能背光pwm:
&pwm1 {
- status = "disabled";
+ status = "okay";
};
复制代码
2)打开kernel/arch/arm/boot/dts/rk3288.dtsi,修改如下:
关闭CTR_GTCLKS:
rockchip,ctrbits = <
(0
|RKPM_CTR_PWR_DMNS
- |RKPM_CTR_GTCLKS
+ // |RKPM_CTR_GTCLKS
复制代码
3)打开kernel/arch/arm/configs/firefly-rk3288_defconfig,修改如下:
修改触摸defconfig配置:
-CONFIG_TOUCHSCREEN_GSLX680=y
+CONFIG_TOUCHSCREEN_GSLX680_MT70817V2=y
复制代码
4)打开device/rockchip/rk3288/rk3288_box/system.prop,修改如下: (此修改需要重新编译上层)
修改图标大小
-ro.sf.lcd_density=160
+ro.sf.lcd_density=320
复制代码
5)打开frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java,修改如下:(此修改需要重新编译上层)
添加屏幕旋转,此修改可以根据自己需求添加
loadSetting(stmt, Settings.System.HIDE_ROTATION_LOCK_TOGGLE_FOR_ACCESSIBILITY,
- "1");
+ "0");
复制代码
三.编译烧写:
1)编译烧写内核:
tvbox-51/kernel$ make firefly-rk3288_defconfig
tvbox-51/kernel$ make firefly-rk3288.img -j4
复制代码
烧写kernel.img和resouce.img
2)编译烧写Android:
tvbox-51$ . build.sh
tvbox-51$ make installclean
tvbox-51$ make -j8
复制代码
烧写system.img和misc.img
对应的补丁和固件wiki地址:

附:如使用自己编译的u-boot,请make rk3288_config 再make

原来的firefly-rk3288.dts中关于rk_screen的代码如下:
&rk_screen {
display-timings = <&disp_timings>;
};
跟上面贴出来的不一致,请问要怎么样修改?

原来的firefly-rk3288.dts中关于rk_screen的代码如下:
&rk_screen {
display-timings = ;
原来理解错了。应该是这样修改。
&lcdc0 {
status = "okay";
rockchip,iommu-enabled = <1>;
rockchip,prop = <PRMRY>;
power_ctr: power_ctr {
rockchip,debug = <1>;
lcd_en:lcd_en {
rockchip,power_type = <GPIO>;
gpios = <&gpio0 GPIO_B5 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};
/*
lcd_cs:lcd_cs {
rockchip,power_type = <GPIO>;
gpios = <&gpio7 GPIO_A4 GPIO_ACTIVE_HIGH>;
rockchip,delay = <10>;
};
lcd_rst:lcd_rst {
rockchip,power_type = <GPIO>;
gpios = <&gpio5 GPIO_C1 GPIO_ACTIVE_LOW>;
rockchip,delay = <0>;
};
*/
};
};
