I have completed an automated and complete zephyr environment on raspberry pi, here. This is an extremely versatile tool as zephyr supports nearly 1000 unique devlopment boards. This project utilizes the nRF52840 USB dongle for an example: wipes the nrfutil boot, compiles zephyr’s suggested MCUboot, programs the dongle over SWD, compiles the associated blinky, signs the binary and programs the dongle.

Very cool - thanks for sharing your hard work!
TS-Russell,
You bet, if there is any path forward in turning my hard work into cash a heads-up would be appreciated.

We mostly only deal with hardware partnerships…give me a shout if you have a novel board design that might suit the our site 
LMAO, yes but what board programs all the novel boards? In this case Sparkfun could rebrand to program all other unique boards. Is Sparfun promoting a single tool to program
all other unique boards? OpenOCD is a jtag/swd solution able to program FPGA’s(novel boards).
Respectfully,

So, the project has just confirmed autonomous Vibe programming. Input text the RPI, zephyr tool chain builds, and programs the vibe onto a supported zephyr hardware.
