Red square issue with raspberry_video (Lepton 3.5, breakout board v2.0, Raspberry Pi4)

[vittoriaCip]

Hi everyone,
I am working on a project that involves a Lepton 3.5 with a Breakout Board v2.0 and a Raspberry Pi4. My problem is that even if I follow all the steps described on the Github page of GroupGets dedicated to LeptonModule, once the raspberrypi_video is launched on my Raspberry Pi4 (attached to lepton 3.5 + breakout board v 2.0) I get a red square on the top-left corner of a bigger black square. Moreover, the button "Perform FCC" also doesn't work. I have tried to follow some suggestions found on other threads and I also tried other combinations for the pins that connect the breakout board to the Raspberry Pi 4. Unfortunately, the problem is still here and I cannot find a solution.
Does anyone have the same problems and have found a solution? Your help will be truly appreciated.
Thanks.

I had this issue with the Lepton 2.5 I found this useful troubleshooting tip for this error. On this site, near the end they recommend trying this :

Remember, if you have issues getting the camera to work with pin 26 on the Pi, you may need to adjust the CS pin to pin 24 (next to the CLK pin)

Let me know if that worked for you.
