PSOC 6 WiFi-BT Pioneer Kit

Overview

The PSOC 6 WiFi-BT Pioneer Kit (CY8CKIT-062-WiFi-BT) is a low-cost hardware platform that enables design and debug of the PSOC 62 MCU and the Murata LBEE5KL1DX Module (CYW4343W WiFi + Bluetooth Combo Chip).

The PSOC 6 WiFi-BT Pioneer Kit features the PSOC 62 MCU: a dual-core MCU, with a 150-MHz Arm Cortex-M4 as the primary application processor and a 100-MHz Arm Cortex-M0+ that supports low-power operations, 1MB of Flash, 288KB of SRAM, 104 GPIO, 7 programmable analog blocks, 56 programmable digital blocks, Full-Speed USB, a serial memory interface, a PDM-PCM digital microphone interface, and industry-leading capacitive-sensing with CapSense.

The PSOC 6 WiFi-BT Pioneer board offers compatibility with Arduino shields.

The Cortex-M0+ is a primary core on the board’s SoC. It starts first and enables the CM4 core.

Hardware

For more information about the PSOC 62 MCU SoC and CY8CKIT-062-WiFi-BT board:

Supported Features

The board configuration supports the following hardware features:

Interface

Controller

Driver/Component

NVIC

on-chip

nested vectored interrupt controller

SYSTICK

on-chip

system clock

PINCTRL

on-chip

pin control

UART

on-chip

The default configuration can be found in the Kconfig boards/cypress/cy8ckit_062_wifi_bt/cy8ckit_062_wifi_bt_cy8c6247_m0_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.

Serial Port

The PSOC 62 MCU SoC has 9 SCB blocks 8 of each can be configured as UART interfaces for serial communication. At the moment UART5 on SCB5 and UART6 on SCB6 are configured. SCB5 is connected to the onboard KitProg2’s USB-UART Bridge, SCB6 to P12_0, P12_1 pins on the J3 of the Arduino Uno R3 compatible PSOC 6 I/O header.

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 CY8CKIT-062-WiFi-BT includes an onboard programmer/debugger (KitProg2) with mass storage programming to provide debugging, flash programming, and serial communication over USB. There are also PSOC 6 program and debug headers J11 and J12 that can be used with Segger J-Link. A watchdog timer is enabled by default. To disable it call Cy_WDT_Unlock() and Cy_WDT_Disable().

Only the CM0+ core starts by default after the MCU reset. In order to have CM4 core working FW for both cores should be written into Flash. CM0+ FW should starts the CM4 core at one point using Cy_SysEnableCM4(CM4_START_ADDRESS); call. CM4_START_ADDRESS is 0x10060000 in the current configuration. The CM0+/CM4 Flash/SRAM areas are defined in dts/arm/infineon/cat1a/legacy/psoc6.dtsi.

Build the project for CM0+

west build -b cy8ckit_062_wifi_bt/cy8c6247/m0

Switch the DevKit into CMSIS-DAP mode using SW3 (LED2 should blink) and flash the board:

$<openocd_path>\bin\openocd -c "source [find interface/cmsis-dap.cfg]" \
   -c "transport select swd" -c "source [find target/psoc6.cfg]" \
   -c "if [catch {program {<zephyr_path>\samples\hello_world\build\zephyr\zephyr.elf}} ] \
      { echo {** Program operation failed **} } \
      else { echo {** Program operation completed successfully **} }" \
   -c "reset_config srst_only;reset run;psoc6.dap dpreg 0x04 0x00;shutdown"

Switch the DevKit back using SW3. Open a serial terminal (minicom, putty, etc.) and connect to the board with the following settings:

  • Speed: 115200

  • Data: 8 bits

  • Parity: None

  • Stop bits: 1

Reset the board and the following message will appear on the corresponding serial port:

***** Booting Zephyr OS zephyr-v1.13.0-1877-g9d14874db1 *****
Hello World! cy8ckit_062_wifi_bt
