请问哪吒 D1 开发板拔插 HDMI 显示器, 提示sink do not support this mode 是什么问题? 换了两台显示器了.

哈，有点像是EDID读取到的VID 不支持，每个VID应该对应一种制式，这里可能有两种情况
要么HDMI线的I2C通道异常，读取不到正确的EDID，要么是运气太差，用的两台显示器默认制式不包含在支持列表之内。

这就尴尬了，一度以为不支持hdmi输出。

这样的话回去我再换两台hdmi设备试一试。

@tigger 你的是不是4K显示器？

不是，两个都是最大支持 1920*1080。

@tigger /sys/devices/virtual/hdmi/hdmi/attr是hdmi的调试节点，可以在这里看下hdmi_sink节点，正常会有类似输出

@tigger 默认应该是MIPI输出，切到HDMI输出就好了：

cd /sys/kernel/debug/dispdbg
echo disp0 > name; echo switch1 > command; echo 4 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;

@anruliu 请问要如何修改源代码，才能让固件的默认显示是从HDMI输出呢？
现在的最新版本的源代码，应该是MIPI输出。我把dts里的screen0_output_type改成了3，我看到注释里写就3是HDMI。但是开机的时候哪吒的logo还是没有从HDMI输出，我想起这个开机LOGO可能是在uboot里就显示的，所以我把configs/nezha/uboot-board.dts文件里的screen0_output_type配置也改了，并重新编译了uboot替换到bin下，但还是不生效。

另外就是我知道了这个logo是放在device/config/chips/d1/configs/nezha/configs下的，我有没有办法在不修改图片片源的情况下，把logo拉到自动适应满hdmi屏幕呢？

搞定,谢谢大佬:

怎么设置hdmi分辨率呢？还是自动检测的？

DOT小文哥 LV 8

@tigger

echo 4 10 0 0 0x4 0x101 0 0 0 8 > param;

这里第二个参数是分辨率，按照.dts注释里写的：

0screenx_output_mode   (used for hdmi output, 
0:480i 
1:576i 
2:480p 
3:576p 
4:720p50
5:720p60 
6:1080i50 
7:1080i60 
8:1080p24 
9:1080p50 
10:1080p60
)

证明一下我重新编译并替换了uboot

D1哪吒开发板默认输出改成HDMI

fengf LV 2

@tigger 请问你是怎么解决这个问题的，我也碰到同样的问题啦sink do not support this mode，能参考一下你的dts吗？

@fengf

后来改成启动默认就是HDMI：
