Overview

The Renesas RZ/G2LC SMARC Evaluation Board Kit (RZ/G2LC-EVKIT) consists of a SMARC v2.1 module board and a carrier board.

  • Device: RZ/G2LC R9A07G044C22GBG

    • Cortex-A55 Dual, Cortex-M33
    • BGA361pin, 13mmSq body, 0.5mm pitch

  • SMARC v2.1 Module Board Functions

    • DDR4 SDRAM: 1GB 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 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 peripheral functions.
    • For power supply, a mounted USB Type-C receptacle supports the USB PD standard.

Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

Applications for the rzg2lc_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.

Flashing

RZ/G2LC-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/G2L, RZ/G2LC, RZ/G2UL 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 OpenAMP related stuff Integration for RZ/G2L, RZ/G2LC and RZ/G2UL" of Release Note for RZ/G Multi-OS Package V2.0.2_ to add the layer for Multi-OS Package.

    .. code-block:: console

    $ cd ~/rzg_vlp_<pkg ver> $ unzip <Multi-OS Dir>/r01an5869ej0202-rzg-multi-os-pkg.zip $ tar zxvf r01an5869ej0202-rzg-multi-os-pkg/meta-rz-features_multi-os_v2.0.2.tar.gz $ bitbake-layers add-layer ../meta-rz-features/meta-rz-multi-os/meta-rzg2l

  3. Start the build:

    .. code-block:: console

    $ MACHINE=smarc-rzg2lc 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-rzg2lc.srec | | | | | | fip-smarc-rzg2lc.srec | +---------------+------------------------------------------------------+ | Flash Writer | Flash_Writer_SCIF_RZG2LC_SMARC_DDR4_1GB_1PCS.mot | +---------------+------------------------------------------------------+

  4. Follow "4.2 Startup Procedure" of SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL 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)

  5. Follow "4.3 Download Flash Writer to RAM" of SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide_ to download Flash Writer to RAM

  6. Follow "4.4 Write the Bootloader" of SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide_ to write the boot loader to the target board by using Flash Writer.

  7. 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)

  8. Follow "3. Preparing the SD Card" of SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide_ to write files to the microSD Card

  9. Copy zephyr.bin file to microSD card

  10. Follow "4.4.2 CM33 Sample Program Invocation with u-boot" from the beginning to step 4 of Release Note for RZ/G Multi-OS Package V2.0.2_

  11. 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
