求助:firefly3288 android5.1 HDMI无输出,没显示

本帖最后由 yubang 于 2016-10-21 10:21 编辑

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720P60HZ),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)
[    0.000000] rkclk_init_clks: cnt_parent = 7

[    1.833025] rockchip-hdmiv2 ff980000.hdmi: sucess output HDMI.

拔掉hdmi线的内核打印:

rk_fb_switch_screen: wait update_regs_wait timeout
rk3288-lcdc lcdc1: no layer is used,go to standby!

重新插入hdmi线的内核打印:

hdmi connect to lcdc1
switch:en=1,lcdc_id=1,screen type=6,cur type=6

pixel clk is 74250000 tmds clk is 74250000
rockchip-hdmiv2 ff980000.hdmi: sucess output HDMI.

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

我看了rk3288.dtsi 这个文件,里面跟hdmi相关的部分是:

        };

        lcdc1: lcdc@ff940000 {

                rockchip,prop = <EXTEND>;

                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,
