.. zephyr:board:: cy8cproto_041tp

Overview

The PSOC™ 4100T Plus CAPSENSE™ Prototyping Kit (CY8CPROTO-041TP) enables you to evaluate and develop applications using the PSOC™ 4100T Plus 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 128 KB Flash and 16 KB SRAM, and includes a wide range of configurable peripherals such as SAR ADC, 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 32 KB of SRAM
- Direct memory access (DMA)
- Low-power 1.71 V to 5.5 V operation
- Deep sleep mode with 6 μA always-on touch sensing
- Active touch detection and tracking with 200 μA (average)
- Real Time clock-SW is available
- Power supply: 3.3 V or 5 V operation

Programming and Debugging

Building

Here is an example for building the :zephyr:code-sample:hello_world sample application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: cy8cproto_041tp :goals: build

Flashing

The CY8CPROTO-041TP 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.

.. tabs:: .. group-tab:: Windows

     .. code-block:: shell

        # 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 cy8cproto_041tp -p always samples/hello_world

        west flash
        west debug

  .. group-tab:: Linux

     .. code-block:: shell

        # 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 cy8cproto_041tp -p always 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.
