各位好，
我在firefly3288上运行android5.1（firefly百度网盘下载的源码）的代码； 代码中原来是支持vga和hdmi的；

我对代码进行了改动，将vga的支持去掉，只用 hdmi；
改动后，重新编译，更新各个映像；
现在板子能够正常启动进入到系统命令行， 插入hdmi，能够检测到（检测到720P 60HZ），但是 却没有显示；

查看内核的启动log， 发现与hdmi相关的都是正常的；

请教各位， 为什么这样呢？ 是不是我的改动哪里没有完成？
（我做的改动包括两个地方：
1）把dst文件与vga相关的去掉；
2）内核中把firefly vga的配置去掉；
)

以下是内核的log： （与hdmi相关的部分）

请教各位， 这样的情况下hdmi没输出，可能是哪方面的问题呀 ？
（所用的hdmi显示器应该是没问题的，这个可以排除； 而板子，hdmi应该也没问题， 这么简单的电路）

谢谢；

去rk3288.dtsi 把hdmi改成lcdc0应该就好了

请同步代码到最新，然后在最新版本上修改看看

我看了rk3288.dtsi 这个文件，里面跟hdmi相关的部分是：
hdmi: hdmi@ff980000 {
compatible = “rockchip,rk3288-hdmi”;
reg = <0xff980000 0x20000>;
interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;
pinctrl-names = “default”, “sleep”;
pinctrl-0 = <&i2c5_sda &i2c5_scl>;
pinctrl-1 = <&i2c5_gpio>;
clocks = <&clk_gates16 9>, <&clk_gates5 12>;
clock-names = “pclk_hdmi”, “hdcp_clk_hdmi”;
status = “disabled”;
};

lcdc0: lcdc@ff930000 {
	compatible = "rockchip,rk3288-lcdc";
	rockchip,prop = <PRMRY>;
	rockchip,pwr18 = <0>;
	rockchip,iommu-enabled = <0>;
	reg = <0xff930000 0x10000>;

	pinctrl-0 = <&lcdc0_lcdc>;
	pinctrl-1 = <&lcdc0_gpio>;
	status = "disabled";
	clocks = <&clk_gates15 5>, <&dclk_lcdc0>, <&clk_gates15 6>, <&pd_vop0>;
	clock-names = "aclk_lcdc", "dclk_lcdc", "hclk_lcdc", "pd_lcdc";
};

lcdc1: lcdc@ff940000 {
	compatible = "rockchip,rk3288-lcdc";
	rockchip,prop = <EXTEND>;
	rockchip,pwr18 = <0>;
	rockchip,iommu-enabled = <0>;
	reg = <0xff940000 0x10000>;
	interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
	status = "disabled";
	clocks = <&clk_gates15 7>, <&dclk_lcdc1>, <&clk_gates15 8>, <&pd_vop1>;
	clock-names = "aclk_lcdc", "dclk_lcdc", "hclk_lcdc", "pd_lcdc";
};

不知道你提到的hdmi 改成 lcdc0， 是指哪处 ？

因为刚接触3288， 很多不了解， 望不吝指教，谢谢！

谢谢！

从网盘下载了代码后，我同步过一次，那时代码应该是更新到2016年7月份的； 是否这两三个月的更新， 有和我遇到的这个问题相关的呢？

请烧录官方固件试试，确定是否是可以，如果可以可排除是硬件问题，

楼主 解决了吗？
