Apalis iMX8 Unconnected CSI and DSI

I am developing a carrier board for the Apalis iMX8QM WB IT, 4GB or 8GB. I won’t be using the type-specific DSI or CSI interfaces, but there is no information in the datasheet or carrier board design guide on what to do with these unconnected pins (leave floating, pull-down, etc). The iMX8 hardware developer’s guide from NXP says every CSI and DSI pin (listed below) should each individually be pulled down to ground with a 10k resistor.

Should I leave the pins floating or pulled-down?

The pins in question:

  • DSI: 95, 97, 131, 133
  • CSI: 101, 103, 107, 109, 113, 115, 119, 121, 125, 127, 137, 139, 143, 145, 149, 151, 155, 157, 161, 163

You can left that pins unconnected (floating). Please refer to the Ixora carrier board design as a reference.
