HDMI is not getting enabled in my personally designed carried board based on Jetson TX2.
I am getting following error.
nvidia@tegra-ubuntu:~$ dmesg |grep hdmi
[ 0.453356] hdmi: couldn't get regulator vdd_hdmi_5v0: -517

Hi, did you follow the OEM DG to design HDMI part? There is a reference schematic in DLC, are you following that? Per your log info, the vdd_hdmi_5v0 is not enabled.
Yes I have followed OEM DG to design HDMI. I have provided direct +5VDC for it. DDC wire (AUX/I2C)I have connected to on board EEPROM programmed with VESA 24bit 640x480 resoultion edid. When I run following command HDMI-1 is not listed and my display is connected to HDMI-1 port.

Any news about that?
Hi EmHardy,
Do you use 5V0_HDMI_EN to switch the HDMI 5V output? You can check the reference schematic about this. It should not be a direct 5V to that.
We have made our custom carrier board and HDMI_5V is direct from 5V supply, and problem has solved. We were using HPD active high, but in device tree HPD is defined as active low.
Glad to here that. But better to follow guide to use EN for HDMI_5V as there might be potential risks if not.
Could you please tell me where to modify the HPD part? We got the same question.
Hi EmHardy, Hi Trumany
We have made our custom carrier board and HDMI_5V is direct from 5V supply too .My hpd signal become high from low when our custom carrier board powers on.BUT there is nothing when we catch the signal of the ehdmi i2c.We think the tx2i might does not identify the HPD high signal,and we think there is some proble about the HDMI_supply_en, HOW can I make my custom carrier board’s HDMI work normally.
I am getting following error too.
hdmi: couldn’t get regulator vdd_hdmi_5v0: -517
Please check the device tree to change the “TEGRA_DC_OUT_HOTPLUG_LOW” to “TEGRA_DC_OUT_HOTPLUG_HIGH”.
hdmi: couldn’t get regulator vdd_hdmi_5v0: -517
This error should not cause the driver to hang. If it hangs, please change the vdd_hdmi_5v0 to battery_reg as a dummy regulator.
Hi,WayneWWW
I have changed the “TEGRA_DC_OUT_HOTPLUG_LOW” to “TEGRA_DC_OUT_HOTPLUG_HIGH”.and vdd_hdmi_5v0_supply to &battery_reg.But HDMI is not getting enabled.It seem to the .DTB files have some problem.

Do you use the same pin connection as our devkit? I don’t see you schematic in this post.
Hi,WayneWWW
