| Overview |
| ******** |
| |
| The RA2L1 MCU Group Capacitive Touch Evaluation System (RTK0EG0022S01001BJ) is a |
| kit created for evaluating the RA2L1 MCU Group Capacitive Touch Sensing Unit (CTSU). |
| |
| RTK0EG0022S01001BJ is composed of two boards: The RA2L1 Cap Touch CPU Board is mounted with an |
| RA2L1 MCU which includes an on-chip CTSU. The Capacitive Touch Application Board Capacitive Touch |
| Application Board is equipped with self-capacitance touch buttons, wheel and slider electrodes, and LEDs |
| touch electrodes. |
| |
| Renesas RA2L1 Microcontroller Group has following features |
| |
| - 48MHz, Arm Cortex-M23 core |
| - 256kB or 128kB Code Flash, 8kB Data Flash, 32kB SRAM (divided on 2 equal areas |
| with- and without- ECC support) |

| Supported Features |
| ================== |
| |
| .. zephyr:board-supported-hw:: |
| |
| Programming and debugging |
| ************************* |
| |
| Building & Flashing |
| =================== |
| |
| You can build and flash an application with an external J-Link debug adapter connect to |
| J1 connector. |
| :ref:`build_an_application` and |
| :ref:`application_run` for more details. |
| |
| Here is an example for building and flashing the :zephyr:code-sample:`blinky` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: rssk_ra2l1 |
| :goals: build flash |
| |
| |
| Debugging |
| ========= |
| |
| Debugging also can be done with an external J-Link debug adapter connected to |
| J1 connector. |
| For the debug log output through UART console, you need to connect a USB cable |
| from the host PC to the USB Serial Conversion on CN5. |
| The following command is debugging the :zephyr:code-sample:`blinky` application. |
| Also, see the instructions specific to the debug server that you use. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: rssk_ra2l1 |
| :maybe-skip-config: |
| :goals: debug |
| |
| Or you can use Segger Ozone (`Segger Ozone Download`_) for a visual debug interface |
| |
| Once downloaded and installed, open Segger Ozone and configure the debug project |
| like so: |
| |
| * Target Device: R7FA2L1AB |
| * Target Interface: SWD |
| * Target Interface Speed: 4 MHz |
| * Host Interface: USB |
| * Program File: <path/to/your/build/zephyr.elf> |
