hello WayneWWW:
Thank you very much!

hello WayneWWW:
I disable the device tree nvdisplay@15200000,nvdisplay@15210000,nvdisplay@15220000.But HDMI still outputs logo NVIDIA.and EMI problems still exist on the carrier board. Can I turn off HDMI output completely? Or what hardware ways to eliminate EMI?
Note:The carrier board is the official board of NVIDIA.
Thank you!

Sorry that I forgot the logo. The logo is enabled in cboot but not kernel.

To disable the logo, you could just remove the display driver from cboot makefile.

The path is /bootloader/partner/common/drivers/display
