PSOC™ 4100S Max pioneer kit

Overview

The PSOC™ 4100S Max Pioneer Kit (CY8CKIT-041S-MAX) enables you to evaluate and develop applications using the PSOC™ 4100S Max microcontroller, part of Infineon’s PSOC™ 4 family. The device integrates an Arm Cortex-M0+ CPU running up to 48 MHz, combining programmable analog and digital subsystems to support flexible mixed-signal designs. It features up to 384 KB Flash and up to 32 KB SRAM, and includes a wide range of configurable peripherals such as SAR ADC, comparators, opamps (CTBm), CapSense™ capacitive touch sensing, and TCPWM for timer/counter/PWM functionality.

32-bit MCU subsystem - 48-MHz Arm® Cortex®-M0+ CPU with single-cycle multiply - Up to 384 KB of flash with read accelerator - Up to 32 KB of SRAM - Direct memory access (DMA) - Low-power 1.71 V to 5.5 V operation - Deep sleep mode with low-power touch sensing - Active touch detection and tracking with low power consumption - Real Time clock support - Power supply: 3.3 V or 5 V operation

Programming and Debugging

The cy8ckit_041s_max board supports the runners and associated west commands listed below.

flash debug rtt debugserver attach
openocd ✅ (default) ✅ (default) ✅ ✅ ✅

Building

Here is an example for building the Hello World sample application.

# From the root of the zephyr repository
west build -b cy8ckit_041s_max samples/hello_world

Flashing

The CY8CKIT-041S-MAX includes an onboard programmer/debugger (KitProg3 [4]) 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 [1] and the ModusToolbox Programming Tools [2] 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 [3] 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

Once configured, you can build and flash applications:

# From the root of the zephyr repository
west build -b cy8ckit_041s_max samples/hello_world
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.
