Overview
4+
********
5+
6+
The RA2L1 MCU Group Capacitive Touch Evaluation System (RTK0EG0022S01001BJ) is a
7+
kit created for evaluating the RA2L1 MCU Group Capacitive Touch Sensing Unit (CTSU).
8+
9+
RTK0EG0022S01001BJ is composed of two boards: The RA2L1 Cap Touch CPU Board is mounted with an
10+
RA2L1 MCU which includes an on-chip CTSU. The Capacitive Touch Application Board Capacitive Touch
11+
Application Board is equipped with self-capacitance touch buttons, wheel and slider electrodes, and LEDs
12+
touch electrodes.

Supported Features
79+
==================

83+
Programming and debugging
84+
*************************
85+
86+
Building & Flashing
87+
===================
88+
89+
You can build and flash an application with an external J-Link debug adapter connect to
90+
J1 connector.
91+
:ref:`build_an_application` and
92+
:ref:`application_run` for more details.
93+
94+
Here is an example for building and flashing the :zephyr:code-sample:`blinky` application.
95+
96+
.. zephyr-app-commands::
97+
:zephyr-app: samples/basic/blinky
98+
:board: rssk_ra2l1
99+
:goals: build flash
100+
101+
102+
Debugging
103+
=========
104+
105+
Debugging also can be done with an external J-Link debug adapter connected to
106+
J1 connector.
107+
For the debug log output through UART console, you need to connect a USB cable
108+
from the host PC to the USB Serial Conversion on CN5.
109+
The following command is debugging the :zephyr:code-sample:`blinky` application.
110+
Also, see the instructions specific to the debug server that you use.
111+
112+
.. zephyr-app-commands::
113+
:zephyr-app: samples/basic/blinky
114+
:board: rssk_ra2l1
115+
:maybe-skip-config:
116+
:goals: debug
117+
118+
Or you can use Segger Ozone (`Segger Ozone Download`_) for a visual debug interface
119+
120+
Once downloaded and installed, open Segger Ozone and configure the debug project
121+
like so:
122+
123+
* Target Device: R7FA2L1AB
124+
* Target Interface: SWD
125+
* Target Interface Speed: 4 MHz
126+
* Host Interface: USB
127+
* Program File: <path/to/your/build/zephyr.elf>
128+
