omapdss error: HDMI I2C timeout reading EDID

[hoverwinter]

Hello, as the title shows, when I use ./build_kernel.sh to compile the kernel for BeagleBoard X15,
and make a SD-Card system following the BB-X15 Getting Started

Then after booting, I got:
omapdss error: HDMI I2C timeout reading EDID
from serial output.

So I can access the board only by SSH/Serial/.. remotely.

How can I fix this problem?

Information:

• Kernel: 4.9.77-ti-r92
• Hardware: Beagleboard X15 RevC
• HDMI: Dell

This usually happens with a non-spec (aka crappy) hdmi cable..

Connect a GND wire between your monitor and you board. Dell usually has a usb-hub on their monitors, so just connect a usb cable..

Then reboot the board.
