PSOC™ Edge E84 AI Evaluation Kit
Overview
The PSOC™ Edge E84 AI kit enables evaluation and development of applications using the PSOC™ Edge E84 Series Microcontroller (MCU) and a multitude of on-board multimedia, Machine Learning (ML), and connectivity features like Raspberry Pi compatible MIPI-DSI displays, analog and digital microphones for audio interfaces, and AIROC™ CYW55513IUBGT base Wi-Fi & Bluetooth combo Murata Type2FY connectivity module. The kit also has 512-Mbit Quad-SPI NOR Flash and 128-Mbit Octal-SPI HYPERRAM™. The board features an on-board programmer/debugger (KitProg3), JTAG/SWD debug headers, expansion I/O header, USB-C connectors, 6-axis IMU sensor, 3-axis magnetometer, barometric pressure sensor, humidity sensor, RADAR sensor, user LEDs, and a user buttor. The MCU power domain and perihporal power domain supports operating voltages of 1.8V and 3.3V.
PSOC™ E84 MCU is an ultra-low-power PSOC™ device specifically designed for ML, wearables and IoT products like smart thermostats, smart locks, smart home appliances and industrial HMI.
PSOC™ E84 MCU is a true programmable embedded system-on-chip with dual CPUs, integrating a 400 MHz Arm® Cortex®-M55 as the primary application processor, a 200 MHz Arm® Cortex®-M33 that supports low-power operations, and a 400 MHz Arm® Ethos-U55 as a neural net companion processor, graphics and audio block, DSP capability, security enclave with crypto accelerators and protection units, high-performance memory expansion capability (QSPI, and Octal HYPERRAM™), low-power analog subsystem with high performance analog-to-digital conversion and low-power comparators, on-board IoT connectivity module , communication channels, programmable analog and digital blocks that allow higher flexibility, in-field tuning of the design, and faster time-to-market.

Programming and Debugging
The kit_pse84_ai board supports the runners and associated west commands listed below.
| flash | debug | debugserver | attach | rtt | |
|---|---|---|---|---|---|
| openocd | ✅ (default) | ✅ (default) | ✅ | ✅ | ✅ |
The KIT-PSE84-AI 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 the Infineon OpenOCD and Edge Protect Security Suite (edgeprotecttools).
Flashing
Applications for the kit_pse84_ai/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_ai/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 -p -b kit_pse84_ai/pse846gps2dbzc4a/m55 samples/hello_world --sysbuild
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 # Do a pristine build once after setting CMake argument west build -b kit_pse84_ai/pse846gps2dbzc4a/m33 -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 kit_pse84_ai/pse846gps2dbzc4a/m33 -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 PSOC E84 CM33 core.
