######################

Overview
********

The PSoC 6 BLE Pioneer Kit (CY8CKIT-062-BLE) is a hardware platform that
enables design and debug of the Cypress PSoC 63 BLE MCU.

The PSoC 6 BLE Pioneer Kit features the PSoC 63 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,
an integrated BLE 4.2 radio, 78 GPIO, 7 programmable analog blocks, 12
programmable digital blocks, and capacitive-sensing with CapSense.

The PSoC 6 BLE Pioneer board offers compatibility with Arduino shields, a
512-Mb NOR flash, onboard programmer/debugger (KitProg2), USB Type-C power
delivery system (EZ-PD™ CCG3), 5-segment CapSense slider, two CapSense
buttons, one CapSense proximity sensing header, an RGB LED, two user LEDs,
and one push button.

The CY8CKIT-062-BLE package includes a CY8CKIT-028-EPD E-INK Display Shield
that contains a 2.7-inch E-INK display, a motion sensor, a thermistor, and a
PDM microphone. The kit package also contains a CY5677 CySmart BLE 4.2 USB
Dongle that is factory-programmed to emulate a BLE GAP Central device,
enabling you to emulate a BLE host on your computer.

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

+-----------+------------+-----------------------+


The default configurations can be found in the Kconfig
:zephyr_file:`boards/arm/cy8ckit_062_ble/cy8ckit_062_ble_m0_defconfig` for
Cortex-M0+ and on the Kconfig
:zephyr_file:`boards/arm/cy8ckit_062_ble/cy8ckit_062_ble_m4_defconfig` for
Cortex-M4

System Clock
============

The PSoC 63 BLE 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 63 BLE MCU SoC has 8 SCB blocks and each one can be configured as
UART/SPI/I2C 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 working as a serial console interface. SCB6 to P13_0, P13_1
pins on the J3 of the Arduino Uno R3 compatible PSoC6 I/O header for general
purposes.

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

The CY8CKIT-062-BLE 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 [default].
A watchdog timer is enabled by default. To disable it call Cy_WDT_Unlock() and
Cy_WDT_Disable().

#. Build the Zephyr kernel and the :ref:`hello_world` sample application:

   .. zephyr-app-commands::
      :zephyr-app: samples/hello_world
      :board: cy8ckit_062_ble_m0
      :goals: build
      :compact:

#. Run your favorite terminal program to listen for output. Under Linux the
   terminal should be :code:`/dev/ttyACM0`. For example:

   .. code-block:: console

      $ minicom -D /dev/ttyACM0 -o

   The -o option tells minicom not to send the modem initialization
   string. Connection should be configured as follows:

      - Speed: 115200
      - Data: 8 bits
      - Parity: None
      - Stop bits: 1

#. To flash an image:

   .. zephyr-app-commands::
      :zephyr-app: samples/hello_world
      :board: cy8ckit_062_ble_m0
      :goals: flash
      :compact:

   You should see "Hello World! cy8ckit_062_ble_m0" in your terminal.

Running on Dual Core
********************

#. Build the Zephyr kernel and the :ref:`button-sample` sample application:

   .. zephyr-app-commands::
      :zephyr-app: samples/basic/button
      :board: cy8ckit_062_ble_m4
      :goals: build
      :compact:

#. If you have a USB-Serial adapter, you can connect SBC[UART]-6 on Arduino
   header.  Schematic should be checked for connections.   Run your favorite
   terminal program again now listen for another output.   Under Linux the
   terminal should be :code:`/dev/ttyUSB0`. For example:

   .. code-block:: console

      $ minicom -D /dev/ttyUSB0 -o

   The -o option tells minicom not to send the modem initialization
   string. Connection should be configured as follows:

      - Speed: 115200
      - Data: 8 bits
      - Parity: None
      - Stop bits: 1

#. To flash an image:

   .. zephyr-app-commands::
      :zephyr-app: samples/basic/button
      :board: cy8ckit_062_ble_m4
      :goals: flash
      :compact:

#. Configure Cortex-M0+ to enable Cortex-M4:

   The last step flash the M4 image on the flash.  However, Cortex-M0 by default
   doesn't start the M4 and nothing will happen.  To enable Cortex-M4 CPU,
   repeat the steps on programming and debug and add the following parameter
   when performing the build process.

   .. zephyr-app-commands::
      :zephyr-app: samples/hello_world
      :board: cy8ckit_062_ble_m0
      :goals: build flash
      :gen-args: -DCONFIG_SOC_PSOC6_M0_ENABLES_M4=y
      :compact:

   Now you can press button SW-2 and see LED-9 blink at same time you have the
   "Hello World! cy8ckit_062_ble_m0" in the your terminal.

Board Revision
**************

The CY8CKIT-062-BLE KitProg2 shares connections with Arduino-R3 header.  This
connections may not allow the correct use of shields.  The default board
revision (0.0.0) allows use of default connections.  The use of Arduino headers
are only possible after rework the board and using the revision 1.0.0.

#. Build the Zephyr kernel and the :ref:`hello_world` sample application for
   board revision 1.0.0:

   .. zephyr-app-commands::
      :zephyr-app: samples/hello_world
      :board: cy8ckit_062_ble_m0@1.0.0
      :goals: build
      :compact:

#. The differences from version 0.0.0 to 1.0.0:

+-------------+------------+------------+
| Connection  | 0.0.0      | 1.0.0      |
+=============+============+============+
| CDC-COM RX  | P5_0       | P9_0       |
+-------------+------------+------------+
| CDC-COM TX  | P5_1       | P9_1       |
+-------------+------------+------------+
| R77         |  X         |            |
+-------------+------------+------------+
| R78         |            |   X        |
+-------------+------------+------------+


The P9 pins are available at J2. Those signals should be routed to J6.

J2-2 to J6-14
J2-4 to J6-13

The most complex part is short circuit pins 14 and 15 from U13.  That connect
UART_RTS with UART_CTS from KitProg2.
