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	debugserver	attach	rtt
openocd	✅ (default)	✅ (default)	✅	✅	✅
probe-rs	✅	✅	✅	✅

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

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

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.

Secure Boot

The PSOC™ Edge E84 MCU includes an extended boot stage in ROM that, on reset, jumps to the first application image. The destination is selected by the on-board BOOT SW:

BOOT SW OFF: the ROM extended boot jumps to the first application located in internal RRAM.
BOOT SW ON: the ROM extended boot jumps to the first application located in external flash.

In both cases the first application image must be in MCUboot image format, i.e. it must be preceded by an MCUboot image header (magic number, header size, vector table address, image size) and followed by the trailer with the hash/signature TLVs. Out of the box, the device is not provisioned for secure boot, so the ROM extended boot only checks the image format and hash; no cryptographic signature verification is performed against a provisioned key.

The MCUboot image format is produced automatically by the soc/infineon/edge/pse84/pse84_metadata.cmake helper pse84_add_metadata_secure_hex(), which invokes imgtool sign with the header address, header size and slot size derived from the devicetree memory map. By default this helper does not pass a signing key, which is sufficient for a non-provisioned device.

Enabling Secure Boot

To enable real signature verification by the ROM extended boot, the device must be reprovisioned. Follow sections 2.2.1, 2.2.2 and 2.2.3 of the PSOC™ Edge Security Getting Started Application Note to:

Generate (or import) the OEM signing key pair.
Provision the device with the corresponding public key and lifecycle transition.
Program the desired security counter / anti-rollback value.

After the device has been reprovisioned, the pse84_add_metadata_secure_hex() function in soc/infineon/edge/pse84/pse84_metadata.cmake must be updated so that imgtool sign also receives the signing key and a security counter. The relevant additions are:

${PYTHON_EXECUTABLE} ${IMGTOOL} sign --version "0.0.0+0"
  --header-size ${header_size} --erased-val 0xff --pad-header
  --slot-size ${slot_size} --hex-addr ${header_addr}
  --key <oem-private-key-file>
  --security-counter <value>
  ${INPUT_FILE} ${OUTPUT_FILE}

Where <oem-private-key-file> is the path to the OEM private key file (e.g. a .pem file) matching the public key provisioned into the device, and <value> is the security counter assigned during provisioning. Without these additional parameters, images built for a provisioned device will be rejected by the ROM extended boot.
