This repository contains the board files for the NXP MCXN947 protocard (breakout board). Pracblink, a directory I created that is a modified version of blinky program in zephyr docs that only toggled an LED, and I modified it so that every time the LED changes state, the program also sends a message (light is blinking!) over the UART serial port. Here is a link to the pracblink repo (https://github.com/Blen-E/pracblink.git ). Ensure that the pracblink is in the correct directory (what I named my directory)--> zephyrproject/zephyr/pracblink. Ensure that the mcxn_protocard repo is placed in the correct directory → zephyrproject/boards/mcxn947_protocard.
