Overview
********
The PSOC 62S4 Pioneer kit has a CY8C62x4 MCU, which is an ultra-low-power PSOC device specifically designed for battery-operated analog
sensing applications. It includes a 150-MHz Arm® Cortex®-M4 CPU as the primary application processor, a 100-MHz Arm® Cortex®-M0+ CPU that
supports low-power operations, up to 256 KB Flash and 128 KB SRAM, programmable analog sensing,
CapSense™ touch-sensing, and programmable digital peripherals.

The board features an onboard
programmer/debugger (KitProg3), a 512-Mbit Quad SPI NOR flash, a micro-B connector for USB device
interface, a thermistor, an ambient light sensor, a 5-segment CapSense™ slider, two CapSense™ buttons, two
user LEDs, and a push button. The board supports operating voltages from 1.8 V to 3.3 V for PSoC™ 6 MCU.

Programming and Debugging
*************************

The CY8CKIT-062S4 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 cy8ckit_062s4 -p always samples/basic/blinky

            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 cy8ckit_062s4 -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 6 CM4 core.
