Hi all.
I have recently bought an ili9341 TFT display on Amazon https://www.amazon.nl/-/en/dp/B07QFVBPM ... asin_title to replace the https://www.amazon.nl/-/en/dp/B078J5TS2 ... title&th=1 which is too small for me.
The second display has a ST7753 chip which I setup using the adafruit-st7735r overlay to be used through frame buffers. I've also created a small script that can display a video. Everything was working pretty fine.
I've tried to achieve the same setup with the ew display so that frame buffers can be used. My config.txt file is as follows:I've tried different overlays, as you can see from the above config file. First, the mipi-dbi-spi which doesn't make use of frame buffers though. Then, I've tried the fbtft overlay which is of course in the staging area. Although this overlay uses the frame buffer, when trying to launch my program, the krm driver is not loaded and the offscreen one is used which leads to no video displayed. As a last resource, I've tried to edit the watterot overlay, which makes use of the frame buffers but the result was the same as the other overlays.
Also, I noticed that when uncommenting the vc4-kms-v3d overlay and using the fbtft one, the display outputs the raspberry pi directly.
I'm using the latest raspi OS.
It's been two weeks now since I've tried to make it work and went through a lot of different online resources that explain how to set up the ili9341 display but none of them worked for me.
I would like to receive your help on this.
