You'll only ever get responses if you provide enough information.

You have not stated the part number you are using.

You have not stated that you have confirmed that the I/O pad you are assigning supports LVDS.

The error is telling you that the pin H3 can not be used for LVDS:

"error : pin H3 does not support I/O standard LVDS"

So go and read the data sheet and see if that truly is the case. You can use general purpose I/O pins to emulate LVDS, but it requires an external resistor network.

Cheers,
