INFINEON CYW920829M2EVK-02

Overview

The AIROC™ CYW20829 Bluetooth® LE MCU Evaluation Kit (CYW920829M2EVK-02) with its included on-board peripherals enables evaluation, prototyping, and development of a wide array of Bluetooth® Low Energy applications, all on Infineon’s low power, high performance AIROC™ CYW20829. The AIROC™ CYW20829’s robust RF performance and 10 dBm TX output power without an external power amplifier (PA). This provides enough link budget for the entire spectrum of Bluetooth® LE use cases including industrial IoT applications, smart home, asset tracking, beacons and sensors, and medical devices.

The system features Dual Arm® Cortex® - M33s for powering the MCU and Bluetooth subsystem with programmable and reconfigurable analog and digital blocks. In addition, on the kit, there is a suite of on-board peripherals including six-axis inertial measurement unit (IMU), thermistor, analog mic, user programmable buttons (2), LEDs (2), and RGB LED. There is also extensive GPIO support with extended headers and Arduino Uno R3 compatibility for third-party shields.

System Clock

The AIROC™ CYW20829 Bluetooth® MCU SoC is configured to use the internal IMO+FLL as a source for the system clock. Other sources for the system clock are provided in the SOC, depending on your system requirements.

Fetch Binary Blobs

cyw920829m2evk_02 board requires fetch binary files (e.g Bluetooth controller firmware).

To fetch Binary Blobs:

west blobs fetch hal_infineon

Build blinking led sample

Here is an example for building the Blinky sample application.

# From the root of the zephyr repository
west build -b cyw920829m2evk_02 samples/basic/blinky

Programming and Debugging

The CYW920829M2EVK-02 includes an onboard programmer/debugger (KitProg3) to provide debugging, flash programming, and serial communication over USB. Flash and debug commands use OpenOCD and require a custom Infineon OpenOCD version, that supports KitProg3, to be installed.

Infineon OpenOCD Installation

Both the full ModusToolbox and the ModusToolbox Programming Tools packages include Infineon OpenOCD. Installing either of these packages will also install Infineon OpenOCD. If neither package is installed, a minimal installation can be done by downloading the Infineon OpenOCD release for your system and manually extract the files to a location of your choice.

Note

Linux requires device access rights to be set up for KitProg3. This is handled automatically by the ModusToolbox and ModusToolbox Programming Tools installations. When doing a minimal installation, this can be done manually by executing the script openocd/udev_rules/install_rules.sh.

West Commands

The path to the installed Infineon OpenOCD executable must be available to the west tool commands. There are multiple ways of doing this. The example below uses a permanent CMake argument to set the CMake variable OPENOCD.

# Run west config once to set permanent CMake argument
west config build.cmake-args -- -DOPENOCD=path/to/infineon/openocd/bin/openocd.exe

# Do a pristine build once after setting CMake argument
west build -b cyw920829m2evk_02 -p always samples/basic/blinky

west flash
west debug

# Run west config once to set permanent CMake argument
west config build.cmake-args -- -DOPENOCD=path/to/infineon/openocd/bin/openocd

# Do a pristine build once after setting CMake argument
west build -b cyw920829m2evk_02 -p always samples/basic/blinky

west flash
west debug

Once the gdb console starts after executing the west debug command, you may now set breakpoints and perform other standard GDB debugging on the CYW20829 CM33 core.
