A heavily-modified version of the official firmware that runs on the Qorvo DWM3001CDK (as of 2023-10-30), cleaned up and simplified for easier customization. Features:

• Reproducible: built-in Docker development environment automates away most of the fragile and finicky parts of setting up the Qorvo SDK, SEGGER Embedded Studio, SEGGER J-Link, nRF52 SDK, and nRF command line tools.
• Minimal: based on the official DWM3001CDK CLI project, but significantly simpler in terms of code size and organization. Many source files and folders have been consolidated to make the project much easier to navigate.
• Complete: includes build system, flashing tools, and logging/debugging tools. This is the only repository you need to work with the firmware.
• Portable: run make save-development-environment to generate a 5GB tar file containing the entire development environment. In 10 years from now, when half of these dependencies disappear off the internet, run make load-development-environment and you'll still be able to compile this project.

Note that most of the UCI functionality has been removed, since I didn't end up needing it - only the UART CLI interface remains. Besides that, it has the exact same features as the original version of the firmware, including UWB ranging, calibration features, and more.

# MANUAL ACTION (OPTIONAL): run this command to use my prebuilt development environment, otherwise it'll be automatically built from scratch: docker pull uberi/qorvo-nrf52833-board

make build

# MANUAL ACTION: connect the lower USB port of the DWM3001CDK (labelled J9) to this computer using a USB cable (this is the J-Link's USB port)

make flash

# MANUAL ACTION: disconnect the lower USB port of the DWM3001CDK, and connect the upper USB port instead (labelled J20) (this is the nRF52833's USB port)

make serial-terminal

You should now see a minicom instance connected to the DWM3001CDK, try entering the "help" command to see available options.

TODO: just found this on the Qorvo forums: One initiator, two responders setup:

1. Perform the quickstart steps on three different DWM3001CDK boards, connect them both to power, and open a minicom terminal for each board.
2. Run initf 4 2400 200 25 2 42 01:02:03:04:05:06:07:08 1 0 0 1 2 on one board, and respf 4 2400 200 25 2 42 01:02:03:04:05:06:07:08 1 0 0 1 on another, and respf 4 2400 200 25 2 42 01:02:03:04:05:06:07:08 1 0 0 2 on the last one.
3. In the terminal for the initiator, you should see the distances to each responder.

You'll need Docker, and many of the hardware-facing commands in the Makefile assume you're using Linux. The make serial-terminal command assumes you have minicom, grep, and udevadm installed.

You can develop your custom applications by modifying Src/main.c and other files within Src/. Note that you'll have to manually edit DWM3001CDK-DW3_QM33_SDK_CLI-FreeRTOS.emProject with any file additions/removals/renames. It sounds annoying, and it is, but I still consider it an improvement over directly interacting with the proprietary SEGGER Embedded Studio.
