Hi,

Which bsp are you using in your board? Here have you configured the right boot up commands in u-boot command lines? Could you show your u-boot line setting?
Have a great day,
Dan

thank you for your reply. I am using 4.1.15-1.2.0 BSP. I used the command line which writes "video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24" as the one on your official release note. And I don't know how to show the u-boot line setting.

Hi，

When the u-boot boot up you can press "print", then you can see all the u-boot commands setting.

Here you are using the HDMI screen or only the computer display? And how do you connect your board to the display screen?

Have a nice day

Rita
