FLIR Lepton Hookup Guide with RPI - red square issue

Community Projects
1

I am having problems with connecting FLIR Lepton to Raspberry PI 2.

I used this guide step by step:

https://learn.sparkfun.com/tutorials/fl … okup-guide

I ran the example code. I removed and connected the camera, and still no image is shown.

After a lot of troubleshooting, I may have issues with enabling the SPI and I2C:

  • When I try to enable it from raspi-config, I get this message " *Failed to read active DTB ".

  • I tried spidev_test.c and it worked. So perhaps its not the issue.

  • Everything else in the guide went smoot.

I have no idea what to do, and my job depends on it. Can someone please help me?

I have also encountered the same problem. I tried a multitude of things:

  1. Taking the device out and then reinserting it into the socket

  2. Changing the MOSI pin to ground. From pin 19 to 25.

  3. Bridged C11 on the dev kit.

  4. Moved CS from 26 to 24.

I had IR images a couple times, and then, all of a sudden, I cannot get images, just the red square.

I looked on https://groups.google.com/forum/#!forum/flir-lepton, Sparkfun hook up guide, and https://github.com/groupgets/pylepton/tree/lepton3-dev and nothing provides a clear pathway to get consistent IR images.

I am too, at a loss.
