PSOC™ Edge E84 Evaluation Kit

Overview

The PSOC™ Edge E84 Evaluation Kit (KIT_PSE84_EVAL) enables applications to use the PSOC™ Edge E84 Series Microcontroller (MCU) together with multiple on-board multimedia, Machine Learning (ML), and connectivity features including custom MIPI-DSI displays, audio interfaces, and AIROC™ Wi-Fi and Bluetooth® combo-based connectivity modules.

The PSOC™ Edge E84 MCUs are based on high-performance Arm® Cortex®-M55 including Helium DSP support, an Ethos™-U55 NPU, and a low-power Arm® Cortex®-M33 paired with Infineon’s ultra-low power NNLite hardware accelerator. They integrate 2.5D graphics accelerators and display interfaces, while featuring always-on acoustic activity and wake-word detection, efficient HMI operations, and extended battery life.

The evaluation kit carries a PSOC™ Edge E84 MCU on a SODIMM-based detachable SOM board connected to the baseboard. The MCU SOM also has 128 MB of QSP| Flash, 1GB of Octal Flash, 128MB of Octal RAM, PSOC™ 4000T as CAPSENSE™ co-processor, and onboard AIROC™ Wi-Fi and Bluetooth® combo.

Programming and Debugging

Note

BOOT SW on the board MUST be set to ON for any sample applications to work. On some boards this switch may be under the attached LCD screen.

The kit_pse84_eval board supports the runners and associated west commands listed below.

flash debug

The KIT-PSE84-EVAL 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.

Please refer to the ModusToolbox™ software installation guide to install Infineon OpenOCD.

Flashing

Applications for the kit_pse84_eval/pse846gps2dbzc4a/m33 board target can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Applications for the kit_pse84_eval/pse846gps2dbzc4a/m55 board target need to be built using sysbuild to include the required application for the other core.

Enter the following command to compile hello_world for the CM55 core:

west build -b kit_pse84_eval/pse846gps2dbzc4a/m55 --sysbuild samples/hello_world -- -DOPENOCD=path/to/infineon/openocd/bin/openocd
west flash

Debugging

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

west build -b kit_pse84_eval/pse846gps2dbzc4a/m33 samples/basic/blinky
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 PSOC E84 CM33 core.
