Hello,

I am trying to understand the HDMI driver and trying to run the HDMI test from platform SDK v1.1.0. I have connected HDMI cable in to J8 Connector oF IMX6Q -SDP REV C board.

While running the test it calls hdmi_test function. But id does not  display anything. It asks the question

Do you see the image (y or n)?\n"

I am not able to see anything on HDMI display.

Please help if something is missing in setup.

Thanks

John.

you changed configuration "uboot"?, resolution, frequence????

You need set variable vid_dev0, example:

setenv vid_dev0 hdmi,1280x1080M@75,if=RGB24

setenv vid_dev0 hdmi,1280x960M@75,if=RGB24

setenv vid_dev0 hdmi,1024x768M@75,if=RGB24

I have sucess from vid_dev0 hdmi,1280x960M@75,if=RGB24

Thanks for you reply.

I am using platform SDK unit test to test HDMI display with IPU driver.

According to me there is no uboot requires to run Platform SDK unit test.

correct me if i am wrong.

Thanks,

John.

That is correct, SDK does not use u-boot. SDK has internal routines to do platform initialization.
