HDMI hotplug not working in iMX7D Sabresd.

[deven_solanki]

Hi ,

I am working on imx7d-sabresd board. and I am using NXP i.MX Release Distro 4.9.11-1.0.0 (morty). I am facing issue with HDMI hard plugged in. If I plugged in HDMI cable at the booting time itself then I am getting output on HDMI display. But if I am booting board without plugged in HDMI cable and after complete boot I plugged in HDMI cable then it is not giving any output.

How to resolve this problem?

Thanks in advance

Hi Deven

one can try to debug it checking with oscilloscope signal HDMI_INT_B iI9022A

change on GPIO_EPDC_D13 (MX7D_PAD_EPDC_DATA13__GPIO2_IO13)
