INFINEON CY8CPROTO-062-4343W

Overview

The CY8CPROTO-062-4343W PSoC 6 Wi-Fi BT Prototyping Kit is a low-cost hardware platform that enables design and debug of PSoC 6 MCUs. It comes with a Murata LBEE5KL1DX module, based on the CYW4343W combo device, industry-leading CAPSENSE for touch buttons and slider, on-board debugger/programmer with KitProg3, microSD card interface, 512-Mb Quad-SPI NOR flash, PDM-PCM microphone, and a thermistor.

This kit is designed with a snap-away form-factor, allowing the user to separate the different components and features that come with this kit and use independently. In addition, support for Digilent’s Pmod interface is also provided with this kit.

Hardware

For more information about the PSoC 62 MCU SoC and CY8CPROTO-062-4343W board:

Kit Features:

  • Support of up to 2MB Flash and 1MB SRAM

  • Dedicated SDHC to interface with WICED wireless devices.

  • Delivers dual-cores, with a 150-MHz Arm Cortex-M4 as the primary application processor and a 100-MHz Arm Cortex-M0+ as the secondary processor for low-power operations.

  • Supports Full-Speed USB, capacitive-sensing with CAPSENSE, a PDM-PCM digital microphone interface, a Quad-SPI interface, 13 serial communication blocks, 7 programmable analog blocks, and 56 programmable digital blocks.

The default configuration can be found in the Kconfig

boards/infineon/cy8cproto_062_4343w/cy8cproto_062_4343w_defconfig

System Clock

The PSoC 62 MCU SoC is configured to use the internal IMO+FLL as a source for the system clock. CM0+ works at 50MHz, CM4 - at 100MHz. Other sources for the system clock are provided in the SOC, depending on your system requirements.

Fetch Binary Blobs

cy8cproto_062_4343w board optionally uses binary blobs for features (e.g WIFI/Bluetooth chip firmware, CM0p prebuilt images, etc).

To fetch Binary Blobs:

west blobs fetch hal_infineon

Build blinking led sample

Here is an example for the Blinky application.

cd zephyr
west build -p auto -b cy8cproto_062_4343w samples/basic/blink

OpenOCD Installation

To get the OpenOCD package, it is required that you

  1. Download the software ModusToolbox 3.1. https://softwaretools.infineon.com/tools/com.ifx.tb.tool.modustoolbox

  2. Once downloaded add the path to access the Scripts folder provided by ModusToolbox export PATH=$PATH:/path/to/ModusToolbox/tools_3.1/openocd/scripts

  3. Add the OpenOCD executable file’s path to west flash/debug.

  4. Flash using: west flash –openocd path/to/infineon/openocd/bin/openocd

  5. Debug using: west debug –openocd path/to/infineon/openocd/bin/openocd

Programming and Debugging

The CY8CPROTO-062-4343W includes an onboard programmer/debugger (KitProg2) with mass storage programming to provide debugging, flash programming, and serial communication over USB. Flash and debug commands must be pointed to the Cypress OpenOCD you downloaded above.

On Windows:

west flash --openocd path/to/infineon/openocd/bin/openocd.exe
west debug --openocd path/to/infineon/openocd/bin/openocd.exe

On Linux:

west flash --openocd path/to/infineon/openocd/bin/openocd
west debug --openocd path/to/infineon/openocd/bin/openocd

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.

Errata

Problem

Solution

The GPIO_INT_TRIG_BOTH interrupt is not raised when the associated GPIO is asserted.

This will be fixed in a future release.

GDB experiences a timeout error connecting to a server instance started by west debugserver.

This will be fixed in a future release.
