Colibri i.MX8DX - Configure Device Tree for RS-485 and GPIO RTS

[eric.tx]

Hey @cowboydan,

I don’t have a Toradex demo example for rs485 readily available, but I did find another resolved ticket with a script inside that appears to be working from the customers perspective.

High active RTS in RS485 mode

Hi, I have installed the most recent demo image via TEZI and did some measurements using a Ixora carrier board. Please find my results and the test program attached. The “low active RTS” looks fine i guess (-6V means logic high). However the “high active RTS” looks odd. Can you confirm that this is the expected behavior? ["low active RTS"] ["high active RTS"]
