Azure RTOS threadx on Raspberry Pi PR2040

This sample demonstrates Azure RTOS threadx on Raspberry Pi RP2040 Microcontroller

Contents

File/folder Description
demo_threadx.c Sample source code.
threadx Azure RTOS ThreadX source code and cortex-m0 port.
tx_initialize_low_level.S RP2040 specific low-level initialization code.
main.c RP2040 user application entry point.

Prerequisites

  1. Raspberry Pi Pico board

  2. A terminal emulator (such as Putty or Tera Term to display the output.

  3. Follow chapter 8.2 of Getting Started with Raspberry Pi Pico to setup the build environment on Windows 10.

Build and run the sample

  1. Clone this repository (and threadx as a submodule) alongside the pico-sdk (>= 1.2.0) directory. (This project is an external project depends on pico-sdk)

    git clone --recurse-submodules https://github.com/xiongyu0523/Azure-RTOS-on-Raspberry-Pi-Pico-RP2040

  2. Open a Developer command prompt for VS2019 and go to the cloned project to build

    cd Azure-RTOS-on-Azure-Sphere-Mediatek-MT3620
mkdir build
cd build
# assume PICO-SDK-PATH is set to ../../pico-sdk
cmake .. -G "NMake Makefiles"
# waiting for namke project generation
nmake

  3. Hold the BOOTSEL button on Raspberry Pi Pico and connect micro-USB cable, you will see a new USB drive PRI-PR2 is mounted.

  4. Drag and drop the Azure-RTOS-on-Raspberry-Pi-Pico-RP2040.uf2 file in build folder to the USB drive

Observe the output

Open a terminal and connect to the USB Serial Device (COMx) just enumerated. You will see a statistical data of multiple tasks printed every second and LED is blinking at 1Hz.
