HDMI Hot plug detect

The OEM Product design guide for the Jetson TX1 states that the Hot plug detect (HPD) can be inverting or non-inverting. (Page 36, note 2).

It looks, however, like the HPD is triggered on a falling edge (inverted on the dev kit) exlusively.

How does one go about changing this for non-inverted operation? Ie. how do you trigger the HPD I2C sequence on a rising edge?

Thanks

You need change HPD pin to INT PU in pinmux setting besides schematic change of related part which is not necessary and suggested.

Can I get a little more information here. I am having the same problem as cbreak, and changing the pinmux did not help.
