Article on adding SPI kernel support

David Cofer over at NeuroRobotic Technologies has written an excellent set of articles on how to enable the Jetson TK1’s touch screen SPI to communicate with other devices at speeds up to 25 MHz.

The articles include background on the advantages of using this approach in real life applications, as well as a very good explanation configuring the kernel for SPI, and a wonderful explanation of the sometimes mysterious device tree.

First three parts are up, with more to come! Looky here:

Using the Jetson TK1 SPI – Part 1 (Why is SPI important)

Using the Jetson TK1 SPI – Part 2 (Configuring the kernel for SPI)

Using the Jetson TK1 SPI – Part 3 (Configuring SPI in the device tree)

Why are you still reading this? Go to the articles, it will make you a better person.


  1. Is it possible to enable SPI on standard Jetson kernel, rather than the Grinch? If so, could please give us some tips?
