Overview
4+
********
5+
6+
Renesas Starter Kit+ for RZ/T2L is an evaluation and development kit for the RZ/T2L MPU.
7+
By simply connecting the bundled cable to your PC, you can immediately start evaluation through an
8+
on-board emulator. This product contains rich functional ICs such as Gigabit Ethernet PHY and
9+
Octal Flash so you can evaluate various functions of the RZ/T2L without an extension board.
10+
11+
* On-board RZ/T2L MPU 196-pin (R9A07G074M04GBG)
12+
* Rich functional ICs such as Gigabit Ethernet PHY and Octal Flash
13+
so you can evaluate various functions of the RZ/T2L without an extension board
14+
* Generic interfaces such as Pmod/Grove/QWIIC/mikroBUS
15+
* Pin headers for external extension enable you to evaluate many use cases
16+
* Emulator circuit is mounted, and program debugging can be started by simply connecting USB cable
17+
to PC (two USB cables are included, one for emulator and the other for power supply)
18+
* On-board memory components:
19+
20+
* Octa Flash (512MBit)
21+
* HyperRAM (64Mbit)
22+
* QSPI Serial Flash (128Mbit)
23+
* I2C EEPROM (16Kbit)
24+
25+
* Communication interfaces include:
26+
27+
* Debug interfaces (J-Link OB, MIPI-10, MIPI-20, Mictor-38)
28+
* Ethernet
29+
* CAN
30+
* USB
31+
* RS485
32+
* UART
33+
* I2C
34+
* SPI

Supported Features

==================
52+
53+
.. zephyr: board-supported-hw::
54+
55+
Connections and IOs
56+
===================
57+
58+
By default, the board is configured for use with:
59+
60+
* UART0 connected to the USB serial port (pins G12, G11),
61+
* UART2 connected to the PMOD Header (J25, pins M1, L2),
62+
* LEDs defined as ``led1`` and ``led3``,
63+
64+
The Zephyr console uses UART0.
65+
66+
Programming and Debugging
67+
*************************
68+
69+
Applications for the ``rzt2l_rsk`` board can be
70+
built, flashed, and debugged in the usual way. See :ref:`build_an_application`
71+
and :ref:`application_run` for more details on building and running.
72+
73+
To use J-Link OB on RSK+RZT2L,
74+
75+
1. Open the jumper pin (J9) for switching the debug connection.
76+
77+
2. Connect the micro-USB type-B to J-Link OB USB connector (J10), and then the LED6 is lighted.
78+
79+
Console
80+
=======
81+
82+
The UART port is accessed by USB-Serial port (CN16).
83+
84+
Debugging
85+
=========
86+
87+
Here is an example for building and debugging with the :zephyr:code-sample:`hello_world` application.
88+
89+
.. zephyr-app-commands::
90+
:zephyr-app: samples/hello_world
91+
:board: rzt2l_rsk
92+
:goals: build debug
93+
94+
Flashing
95+
=========
96+
97+
Before using ``flash`` command, the board must be set to xSPI1 boot mode.
98+
99+
.. zephyr-app-commands::
100+
:zephyr-app: samples/hello_world
101+
:board: rzt2l_rsk
102+
:goals: build flash
