Hi,

I set setenv panel HDMI

It works!

.bus	= -1,
	.addr	= 0,
	.pixfmt	= IPU_PIX_FMT_RGB24,
	.detect	= NULL,
	.enable	= do_enable_hdmi,
	.mode	= {
		.name = "HDMI",

Hi Eugene,

I'm having a similar issue where did you set the panel HDMi in uboot or in device tree?

Also where did you get the information for what the methods are and what options are available?
