Overview

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

Connections and IOs

By default, the board is configured for use with:

SCI_UART

• SCI_UART0:

  • TX = Pmod 3A pin 2

  • RX = Pmod 3A pin 3

LED

• LED5 (yelow) = P0_0

• LED6 (yelow) = P0_1

Programming and Debugging (M33/R8)

The rzv2h_evk board supports the runners and associated west commands listed below.

	flash	debug	debugserver	rtt	attach
jlink	✅ (default)	✅ (default)	✅	✅	✅

Applications for the rzv2h_evk board can be built in the usual way as documented in Building an Application.

Console

The UART port for Cortex-M33/Cortex-R8 System Core can be accessed by connecting Pmod USBUART to the upper side of PMOD Type 3A.

Debugging

It is possible to load and execute a Zephyr application binary on this board on the Cortex-M33/Cortex-R8 System Core from the internal SRAM, using JLink debugger (J-Link Debug Host Tools).

Here is an example for building and debugging with the Hello World application.

CM33:

# From the root of the zephyr repository
west build -b rzv2h_evk/r9a09g057h44gbg/cm33 samples/hello_world
west debug

CR8:

# From the root of the zephyr repository
west build -b rzv2h_evk/r9a09g057h44gbg/cr8_0 samples/hello_world
west debug

Flashing

RZ/V2H-EVK is designed to start different systems on different cores. It uses Yocto as the build system to build Linux system and boot loaders to run Zephyr on Cortex-M33/Cortex-R8 with u-boot. The minimal steps are described below.

1. Download Multi-OS Package from the RZ/V2H Easy Download Guide [1]

2. Unzip Multi-OS Package then open “r01qs0077ej****-rzv2h-multi-os-pkg” PDF file.

3. Follow “3.2 Integration of Multi-OS Package related stuff” to build RZ/V2H AI SDK Source Code. Uncomment the following lines in meta-rz-features/meta-rz-multi-os/meta-rzv2h/conf/layer.conf.

#MACHINE_FEATURES_append = " RZV2H_CM33_BOOT"
MACHINE_FEATURES_append = " SRAM_REGION_ACCESS"
#MACHINE_FEATURES_append = " CM33_FIRMWARE_LOAD"
#MACHINE_FEATURES_append = " CA55_CPU_CLOCKUP"

The below necessary artifacts will be located in the build/tmp/deploy/image

Artifacts	File name
Boot loader	bl2_bp_spi-rzv2h-evk-ver1.srec fip-rzv2h-evk-ver1.srec
Flash Writer	Flash_Writer_SCIF_RZV2H_DEV_INTERNAL_MEMORY.mot
SD card image	core-image-weston-rzv2h-evk-ver1.wic.bmap core-image-weston-rzv2h-evk-ver1.wic.gz

4. Carry out 1-9 of Step “1-B Write the Linux files to SD card” at Step 7 Deploy AI Application [2] to prepare SD card.

5. Run the following commands to write zephyr.bin to SD card.

$ sudo mkdir /mnt/sd -p
$ sudo mount /dev/sdb2 /mnt/sd
$ sudo cp /path/to/zephyr.bin /mnt/sd/boot
$ sync
$ sudo umount /mnt/sd

Warning

Change /dev/sdb to your microSD card device name. Use dh -h to check.

6. Insert the SD card into SD1 of RZ/V2H EVK, set up board at eSD mode (DSW1[4:5] = ON, OFF).

7. Turn on the board carefully, see “3.2.2.4 Power Supply” in Getting Started with Flexible Software Package [3] Then, you should see the following message on the console associated with CN12 of RZ/V2H EVK.
