Overview

The KIT_T2G-B-H_EVK kit enables you to evaluate and develop applications using the TRAVEO™ T2G Body High family CYT4BF device. The TRAVEO™ T2G B-H MCU is specifically designed for automotive applications and it is a true programmable embedded system-on-chip, integrating two 350-MHz Arm® Cortex®-M7 as the primary application processor, a 100-MHz Arm® Cortex®-M0+ that supports the following:

Low-power operations
Up to 8 MB flash and 1 MB SRAM
Secure Digital Host Controller (SDHC) supporting SD/SDIO/eMMC interfaces
Programmable analog and digital peripherals that allow faster time-to-market

The evaluation board carries a TRAVEO™ T2G-B-H MCU, an M.2 interface connector for interfacing radio modules based on AIROC™ Wi-Fi & Bluetooth® combos (currently not supported), a Dual-PMOD SMIF connector for interfacing HYPERBUS™ memories, and Arduino headers for interfacing Arduino Shields. In addition, the board features an on-board programmer/debugger (KitProg3), a 512-Mb QSPI NOR flash, a micro-B connector for the USB device interface, three user LEDs, one potentiometer, a Gigabit ethernet port for ethernet applications and two push buttons. The board supports operating voltages from 1.8 V to 5.0 V for TRAVEO™ T2G-B-H MCU.

Programming and Debugging

.. zephyr:board-supported-runners::

Building

Here is an example for building the :zephyr:code-sample:blinky sample application for Cortex®-M0+.

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: kit_t2g_b_h_evk/cyt4bfbche/m0p :goals: build

The same for the first Cortex®-M7 core:

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: kit_t2g_b_h_evk/cyt4bfbche/m7_0 :goals: build

And the second Cortex®-M7 core:

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: kit_t2g_b_h_evk/cyt4bfbche/m7_1 :goals: build

.. note:: Only Cortex®-M0+ core is enabled at startup. To enable the first Cortex®-M7 core, add the next code to Cortex®-M0+ application: Cy_SysEnableCM7(CORE_CM7_0, CY_CORTEX_M7_0_APPL_ADDR);, and the next code to enable the second Cortex®-M7 core: Cy_SysEnableCM7(CORE_CM7_1, CY_CORTEX_M7_1_APPL_ADDR);.

Flashing

The KIT_T2G_B_H_EVK 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 kit_t2g_b_h_evk/cyt4bfbche/m0p -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 kit_t2g_b_h_evk/cyt4bfbche/m0p -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.
