    • Cortex-A55 Dual, Cortex-M33
    • BGA551pin, 15mmSq body, 0.5mm pitch

  • SMARC v2.1 Module Board Functions

    • DDR4 SDRAM: 2GB x 1pc
    • QSPI flash memory: 512Mb x 1pc
    • eMMC memory: 64GB x 1pc
    • The microSD card slot is implemented and used as an eSD for boot
    • 5-output clock oscillator 5P35023 <https://www.renesas.com/en/products/clocks-timing/clock-generation/programmable-clocks/5p35023-versaclock-3s-programmable-clock-generator>_ implemented
    • PMIC power supply RAA215300 <https://www.renesas.com/en/products/power-management/multi-channel-power-management-ics-pmics/raa215300-high-performance-9-channel-pmic-supporting-ddr-memory-built-charger-and-rtc>_ implemented

  • Carrier Board Functions

    • The FFC/FPC connector is mounted as standard for connection to high-speed serial interface for camera module.
    • The Micro-HDMI connector via DSI/HDMI conversion module is mounted as standard for connection to high-speed serial interface for digital video module.
    • The Micro-AB receptacle (ch0: USB2.0 OTG) and A receptacle (ch1: USB2.0 Host) are respectively mounted as standard for connection to USB interface.
    • The RJ45 connector is mounted as standard for software development and evaluation using Ethernet.
    • The audio codec is mounted as standard for advance development of audio system. The audio jack is implemented for connection to audio interface.
    • The CAN connector is implemented for connection to CAN-Bus interface.
    • The Micro-AB receptacles are implemented for connection to asynchronous serial port interface.
    • The microSD card slot and two sockets for PMOD are implemented as an interface for RZ/V2L peripheral functions.
    • For power supply, a mounted USB Type-C receptacle supports the USB PD standard.

  • MIPI Camera Module

    • MIPI Camera Module (MIPI CSI) is included. Image recognition processing can be used with images input with MIPI camera.

Multi-OS processing

The RZ/V2L-EVKIT allows different applications to be executed in RZ/V2L SoC. With its multi-core architecture, each core can operate independently to perform customized tasks or exchange data using the OpenAMP framework. Please see :zephyr:code-sample:rz-openamp-linux-zephyr sample for reference.

Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the rzv2l_smarc board can be built in the usual way as documented in :ref:build_an_application.

Console

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/>_ to the upper side of PMOD 1.

Debugging

It is possible to load and execute a Zephyr application binary on this board on the Cortex-M33 System Core from the internal SRAM, using JLink debugger (:ref:jlink-debug-host-tools).

Here is an example for building and debugging with the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: rzv2l_smarc/r9a07g054l23gbg/cm33 :goals: build debug

Flashing

RZ/V2L-EVKIT 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 with u-boot. The minimal steps are described below.

  1. Follow ''2.2 Building Images'' of SMARC EVK of RZ/V2L Linux Start-up Guide_ to prepare the build environment.

  2. At step (4), follow step ''2. Download Multi-OS Package'' and ''3. Add the layer for Multi-OS Package'' of ''3.2 Integration of OpenAMP related stuff'' of RZ/V2L Quick Start Guide for RZ/V Multi-OS Package_ to add the layer for Multi-OS Package.

.. code-block:: console

$ cd ~/rzv_vlp_<pkg ver> $ unzip <Multi-OS Dir>/r01an7254ej0311-rzv-multi-os-pkg.zip $ tar zxvf r01an7254ej0311-rzv-multi-os-pkg/meta-rz-features_multi-os_v3.1.1.tar.gz $ cd build $ bitbake-layers add-layer ../meta-rz-features/meta-rz-multi-os/meta-rzv2l

  1. Start the build:

.. code-block:: console

$ MACHINE=smarc-rzv2l bitbake core-image-minimal

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

+---------------+------------------------------------------------------+ | Artifacts | File name | +===============+======================================================+ | Boot loader | bl2_bp-smarc-rzv2l_pmic.srec | | | | | | fip-smarc-rzv2l_pmic.srec | +---------------+------------------------------------------------------+ | Flash Writer | Flash_Writer_SCIF_RZV2L_SMARC_PMIC_DDR4_2GB_1PCS.mot | +---------------+------------------------------------------------------+

  1. Follow ''4.2 Startup Procedure'' of SMARC EVK of RZ/V2L Linux Start-up Guide_ for power supply and board setting at SCIF download (SW11[1:4] = OFF, ON, OFF, ON) and (SW1[1:2] = ON, OFF)

  2. Follow ''4.3 Download Flash Writer to RAM'' of SMARC EVK of RZ/V2L Linux Start-up Guide_ to download Flash Writer to RAM

  3. Follow ''4.4 Write the Bootloader'' of SMARC EVK of RZ/V2L Linux Start-up Guide_ to write the boot loader to the target board by using Flash Writer.

  4. Follow ''4.5 Change Back to Normal Boot Mode'' with switch setting (SW11[1:4] = OFF, OFF, OFF, ON) and (SW1[1:2] = ON, OFF)

  5. Follow ''3. Preparing the SD Card'' of SMARC EVK of RZ/V2L Linux Start-up Guide_ to write files to the microSD Card

  6. Copy zephyr.bin file to microSD card

  7. Follow "4.3.2 CM33 Sample Program Invocation with u-boot" from the beginning to step 4 of RZ/V2L Quick Start Guide for RZ/V Multi-OS Package_

  8. Execute the commands stated below on the console to start zephyr application with CM33 core. Here, ''N'' stands for the partition number in which you stored zephyr.bin file.

.. code-block:: console

Hit any key to stop autoboot: 2 => dcache off => mmc dev 1 => fatload mmc 1:N 0x00010000 zephyr.bin => fatload mmc 1:N 0x40010000 zephyr.bin => cm33 start_normal 0x00010000 0x40010000 => dcache on
