RK3399Pro Android 下EDP调试不通
WIKI里面有个EDP的修改办法，但是kernel/arch/arm64/boot/dts/rockchip/rk3399pro-firefly-aiojd4-edp.dts这个文件找不到。请问有高手指点一下怎么改吗? 有技术支持吗？ sleeping 发表于 2021-3-31 10:04有技术支持吗？
可以参考rk3399pro-firefly-aioc-edp.dts leung先森 发表于 2021-3-31 10:43
可以参考rk3399pro-firefly-aioc-edp.dts
我现在参考了这个文件，但是EDP不亮。

不知道问题在哪，HDMI能亮，EDP就不行。然后运行kris@eco:~/rk3399/rockdev/rk3399_mid-eng$ adb shell
rk3399_mid:/ # cat /d/dri/0/summary
结果都是disable。
不知道问题在哪。能帮忙指点一下吗~

问题解决了吗，我也遇到同样的问题，指点一下 EDP的设备树节点配置错了，或者没有配置，导致一部分的GPIO匹配失败了。建议看回驱动源码，反推GPIO 引脚配置要求。（无非是理清需要的引脚别名，找对对应的引脚，配置好输入还是输出，输出的话是高电平还是低电平。）上面的报错主要是引脚匹配失败的报错，先适配好引脚，再看看是否有进一步的报错。
