-The easiest way to get started with the NPU is to use a image from the NXP BSP. This image contains the necessary libraries and kernel to interface the NPU without much configuration.

 - A >= 16GB flash drive, SD card, or other removable block storage to install a Rescue Image, NXP Image, and updated device trees (DTBs) onto the board.
 
+The steps are as generalized as possible to not depend on the boards available RAM to load an image, or the low speeds of JTAG uploading, as the .wic from NXP is >8GB. We will use a ramdisk to boot a "rescue image" fully in RAM, then use dd to write from the removable multimedia (flash drive) to the onboard eMMC (/dev/mmcblk2).

 If everything works properly, you should instantly see your video input streamed to your desktop host. After a few seconds of warming up, the bounding boxes from the [[https://nnstreamer.github.io/gst/nnstreamer/README.html | TensorFlow filter]] will be overlaid on the video. The stream properties can be changed for different resolutions and framerates; see [[https://trac.gateworks.com/wiki/Yocto/gstreamer/streaming | gstreamer/streaming]].
