Including the device tree for TFT touch screen

Post by pijke » Tue Sep 26, 2017 2:25 pm

Hello!

I'm new to working with RedPitaya's and I am trying to add the MI0283QT Adapter Rev 1.5 touch TFT screen as a display for a RedPitaya STEMlab 125-14 (with software version 0.96-86). To do that, I'm using this tutorial: https://redpitaya.readthedocs.io/en/lat ... t/TFT.html

I followed the tutorial, but at a certain point it says:

Code: Select all

The reconfiguration is performed by including the tft-E2.dtsi device tree.
How and where do I add the device tree? I can't find it anywhere. I tried to get it to work without it, but it keeps crashing when I execute startx.

Code: Select all

I have attached the log as an attachment.

I found the device trees (https://github.com/RedPitaya/RedPitaya/ ... ga/dts/tft) but i couldn't find the location where I can add them so the screen works.

Thank you very much in advance.

best regards,
Pijke
