Overview
4+
********
5+
6+
The RZ/V2H high-end AI MPU boasts Renesas' proprietary dynamically reconfigurable processor AI accelerator (DRP-AI3),
7+
quad Arm Cortex-A55 (1.8GHz) Linux processors, and dual Cortex-R8 (800MHz) real-time processors.
8+
Furthermore, the RZ/V2H also includes another dynamically reconfigurable processor (DRP).
9+
This processor can accelerate image processing, such as OpenCV, and dynamics calculations required for robotics applications.
10+
It also features high-speed interfaces like PCIe, USB 3.2, and Gigabit Ethernet,
11+
making it an ideal microprocessor for applications such as autonomous robots and machine vision in factory automation,
12+
where advanced AI processing must be implemented with low power consumption.

Programming and Debugging (M33)
78+
*******************************
79+
80+
.. zephyr:board-supported-runners::
81+
82+
Applications for the ``rzv2h_evk`` board can be built in the usual way as
83+
documented in :ref:`build_an_application`.
84+
85+
Console
86+
=======
87+
88+
The UART port for Cortex-M33 System Core can be accessed by connecting `Pmod USBUART <https://store.digilentinc.com/pmod-usbuart-usb-to-uart-interface/>`_
89+
to the upper side of ``PMOD Type 3A``.
90+
91+
Debugging
92+
=========
93+
94+
It is possible to load and execute a Zephyr application binary on
95+
this board on the Cortex-M33 System Core from
96+
the internal SRAM, using ``JLink`` debugger (:ref:`jlink-debug-host-tools`).
97+
98+
Here is an example for building and debugging with the :zephyr:code-sample:`hello_world` application.
99+
100+
.. zephyr-app-commands::
101+
:zephyr-app: samples/hello_world
102+
:board: rzv2h_evk/r9a09g057h44gbg/cm33
103+
:goals: build debug
104+
105+
Flashing
106+
========
107+
108+
RZ/V2H-EVK is designed to start different systems on different cores.
109+
It uses Yocto as the build system to build Linux system and boot loaders
110+
to run Zephyr on Cortex-M33 with u-boot. The minimal steps are described below.
111+
112+
1. Download Multi-OS Package from the `RZ/V2H Easy Download Guide`_
113+
114+
2. Unzip Multi-OS Package then open "r01qs0077ej****-rzv2h-multi-os-pkg" PDF file.
115+
116+
3. Follow "3.2 Integration of Multi-OS Package related stuff" to build RZ/V2H AI SDK Source Code.
117+
Uncomment the following lines in **meta-rz-features/meta-rz-multi-os/meta-rzv2h/conf/layer.conf**.
118+
119+
.. code-block:: console
120+
121+
#MACHINE_FEATURES_append = " RZV2H_CM33_BOOT"
122+
MACHINE_FEATURES_append = " SRAM_REGION_ACCESS"
123+
#MACHINE_FEATURES_append = " CM33_FIRMWARE_LOAD"
124+
#MACHINE_FEATURES_append = " CA55_CPU_CLOCKUP"
125+
126+
The below necessary artifacts will be located in the build/tmp/deploy/image
127+
128+
+---------------+-------------------------------------------------+
129+
| Artifacts | File name |
130+
+===============+=================================================+
131+
| Boot loader | bl2_bp_spi-rzv2h-evk-ver1.srec |
132+
| | |
133+
| | fip-rzv2h-evk-ver1.srec |

139+
| | core-image-weston-rzv2h-evk-ver1.wic.gz |
140+
+---------------+-------------------------------------------------+
141+
142+
4. Carry out 1-9 of Step "1-B Write the Linux files to SD card" at `Step 7 Deploy AI Application`_ to prepare SD card.
143+
144+
5. Run the following commands to write **zephyr.bin** to SD card.
145+
146+
.. code-block:: console
147+
148+
$ sudo mkdir /mnt/sd -p
149+
$ sudo mount /dev/sdb2 /mnt/sd
150+
$ sudo cp /path/to/zephyr.bin /mnt/sd/boot
151+
$ sync
152+
$ sudo umount /mnt/sd
153+
154+
.. warning::
155+
156+
Change ``/dev/sdb`` to your microSD card device name. Use ``dh -h`` to check.
157+
158+
6. Insert the SD card into SD1 of RZ/V2H EVK, set up board at eSD mode (DSW1[4:5] = ON, OFF).
159+
160+
7. Turn on the board carefully, see "3.2.2.4 Power Supply" in `Getting Started with Flexible Software Package`_
161+
Then, you should see the following message on the console associated with CN12 of RZ/V2H EVK.
162+
163+
.. code-block:: console
