Hello, I am debugging the rgb screen now. The device tree is configured as an attachment, and there is no rgb display now. What is the problem?

Hi @xiang_1001 

你设备树里面的扩展GPIO本身就是这么写的吗?不应该写在i2c下面吗?
panel-simple panel: No GPIO consumer enable found

默认将使能脚拉高,现在可以亮了。

但是颜色不对,现在使用的驱动配置的rgb666,原理图如图。

请问是什么原因影响的?

Hi,

DATA[23:0]的顺序是RGB,你检查看看顺序对不对。
