A week with CrossWorks

  • All features from the old site should still be here.
  • All questions, answers, comments and private messages are converted and still available (old links will redirect, or if that...

Programming and debugging custom nRF5x devices

Programming and debugging the nRF5x on our Developments kits is straight forward. Doing the same when you are using other boards might not be so easy. In this blog post we will explain which components are needed in order to program and debug a nRF5x chip.

The nRF chip is connected to a Debug unit through an interface called "Serial Wire Debug", or "SWD" for short. The debug unit acts as a bridge between the chip and your PC. It communicates with the programming and debugging software on your PC through a “Debug interface”. Your PC must have a driver...
