L4T 21.7 SPI


I have basically 2 questions:

  1. How can I enable SPI on 21.7 such that I can see /dev/spidev0.0?
  2. Why isn’t that enabled by default on a dev board?

For question 1, you may read this. It may be a bit old and not R21.7 but might give you most of it.

For question 2, I suppose it’s because the TK1 devkit doesn’t embed any SPI device by default, but you may find better answer in the above mentioned link.
