General Information

• Official RZ/V2L Website
  • Please review the Documentation & Downloads section
• Board Documentation
  • Since the RZ/V2L and RZ/G2L devices are pin compatible, the same evaluation board design is used for both.
• Linux Board Support Package Download
  • The BSP is currently still in pre-release and must be obtained directly from your Renesas Sales representative.

Sharing of RZ/G2L Board Documentation

• Since the RZ/V2L and RZ/G2L devices are pin compatible, they share the exact same evaluation board design. Please refer to the RZ/G2L SMARC board page for reference.
• Board setup (button and switch) information
• LCD Monitors

Getting Started

1. Linux BSP Components

• Obtain the Linux BSP package (rzv2l_linux-pkg_ver0.8.0.zip) from the same Renesas representative that you received your board from. Unzip the contents and copy to a Linux PC.
• Obtain the Codec Library package (RTK0EF0045Z15001ZJ_0_4_0.tar.bz2) from the same Renesas representative that you received your board from. Unzip the contents and copy to a Linux PC.
• Download the RZ/G2L Mali Graphic Library package (RTK0EF0045Z13001ZJ-v0.51_EN.zip) from this link to enable graphs. This package is also used for this RZ/V2L board. Copy the ZIP file to a Linux PC.

2. Build Environment

• To build the BSP, you will need a Linux PC running Ubuntu 20.04. Only this Host OS version was tested.
• You can use a Linux PC (recommended) or a Virtual Machine.

3. Build the BSP

• The instructions for building the BSP are located in the Release Note document that is included in the rzv2l_linux-pkg_ver0.8.0.zip file package.
• ⚠️ If you are building core-image-weston, you need to add Mali Graphics library mentioned in step 1.
• A summary of the instructions located in the Release Note are below. Simple Copy/Paste the commands.

Simple build instructions for BSP v0.8

These instructions are a summary of what is explained in the BSP Release Note. # Extract package $ mkdir rzv2l_bsp_v0.8 $ tar -xf rzv2l_bsp_v080.tar.gz -C rzv2l_bsp_v0.8 $ cd rzv2l_bsp_v0.8 # Copy/Move the 'Mali Graphics library' Zip file (RTK0EF0045Z13001ZJ-v0.51_EN.zip) under our BSP directory. # Then, we will un-zip it and install it. $ unzip RTK0EF0045Z13001ZJ-v0.51_EN.zip $ cd RTK0EF0045Z13001ZJ-v0.51_EN/proprietary $ ./copy_gfx_mmp.sh ../../meta-rzv $ cd ../.. # Set up Yocto Environment $ source poky/oe-init-build-env $ cp ../meta-rzv/docs/template/conf/smarc-rzv2l/*.conf ./conf/ # Build $ bitbake core-image-minimal $ bitbake core-image-weston $ bitbake core-image-minimal -c populate_sdk

4. Prepare an SD Card

• The evaluation boards can be booted from SD Cards. The SD card must be formatted and loaded using a Linux PC. A helpful script has been created (usb_sd_partition) that you can run on your Linux PC.

• Insert your micro SD card into a USB-SD-Card reader and then plug into a Linux PC.

• Use the commands below to download the formatting script and run. Please select your card and choose the default settings.

$ wget https://raw.githubusercontent.com/renesas-rz/rzg2_bsp_scripts/master/usb_sd_partition/usb_sd_partition.sh
$ chmod +x usb_sd_partition.sh
$ ./usb_sd_partition.sh

• Use the commands below to copy the files you build with the BSP to the SD card. Start in the base of your Yocto BSP.

# Change to the Yocto output directory that contains the files
$ cd build/tmp/deploy/images/smarc-rzv2l

# Copy the Linux kernel and Device Tree to partition 1
$ sudo cp -v Image /media/$USER/RZ_FAT
$ sudo cp -v r9a07g054l2-smarc.dtb /media/$USER/RZ_FAT

# Copy and expand the Root File System to partition 2
$ sudo tar -xvf core-image-weston-smarc-rzv2l.tar.gz   -C /media/$USER/RZ_ext
    (or if NOT using graphics)
$ sudo tar -xvf core-image-minimal-smarc-rzv2l.tar.gz   -C /media/$USER/RZ_ext

# Make sure all files are finished writing before removing the USB card reader from the PC
$ sync

• Safely remove your USB card reader by right clicking on the drive icon (either RZ_FAT or RZ_ext) in Ubuntu and selecting "Eject"

5. Power the Board and Connect to the Serial Port

• Supply power the board using the USB-C connection on the carrier board labeled "Power Input"
• On the carrier board, press the red button in order to turn on power to the board. The green LED labeled "Carrier PWR On" will be lit when power is on.
• Now that the board is powered, plug a USB micro cable into the carrier board to the USB connector labeled "SER 3 UART". Use a serial terminal program to interact as you board. With a Linux PC, we recommend using "putty" (connects to /dev/USB0), and with a Windows PC we recommend "TeraTerm" that connects to COMx. The baud rate of the Serial connection is 115200 bps.
• Press the blue reset button, and then "u-boot" will start. Within 3 seconds, press the space bar on your keyboard in order to stop the auto-boot sequence.

6. Switch settings for the CPU SOM board.

• The SOM board contains a eMMC Flash device and a Micro SD Card socket. On the SOM board, you can only use one or the other because they are both connected to the same peripheral channel on the RZ/V2L.
• Set the switches on the SOM board to what you want to use.
• ⚠️ u-boot environment variables are always stored in eMMC Flash (not SPI flash). This means if you change switch SW1-2 to OFF on the SOM board, you cannot access saved u-boot environments variables and you will always get the message "*** Warning - MMC init failed, using default environment"
• Note that the SD Card slot on the Carrier board will always work regardless of the setting of SW1-2 because it uses a separate peripheral channel on the RZ/V2L.
• On the SOM (CPU) board, there is a little switch (SW1) near the SD card socket.

SOM board uses SD Card socket                 SOM board uses eMMC Flash
SW1-1 = ON/OFF(JTAG)                          SW1-1 = ON/OFF(JTAG)
SW1-2 = ON                                    SW1-2 = OFF
      +-----+                                       +-----+
      | ON  |                                       | ON  |
      | = = |                                       | =   |
      |     |                                       |   = |
      | 1 2 |                                       | 1 2 |
      +-----+                                       +-----+

7-1. Boot the Board using SD Card on Carrier Board (Recommended)

• Insert the SD card into the socket on Carrier Board.

┌─────┬─────┬─────┐
│     │ SOM │     │
│     └─────┘     │
│  Carrier Board  │
│     ┌─┐         │
└─────┴─┴─────────┘
       ↑
 SD Card Socket

• Press the blue reset button, and then "u-boot" will start. Within 3 seconds, press the space bar on your keyboard in order to stop the auto-boot sequence.
• At the u-boot prompt ( => ), enter the following commands to boot the board:

   # Create command macros and save them:
=> setenv sd_boot_carrier1 'mmc dev 1 ; fatload mmc 1:1 0x48080000 Image ; fatload mmc 1:1 0x48000000 /r9a07g054l2-smarc.dtb'
=> setenv sd_boot_carrier2 'setenv bootargs 'root=/dev/mmcblk1p2 rootwait' ; booti 0x48080000 - 0x48000000'
=> setenv bootcmd 'run sd_boot_carrier1 sd_boot_carrier2'
=> saveenv

   # Reset the board and it will automatically boot

7-2. Boot the Board using eMMC Flash on SOM Board

• Set switch SW1-2 = OFF
• The boot loader (u-boot) by default will try to boot from eMMC after 3 seconds.
• Press the blue reset button and wait.

7-3. Boot the Board using SD Card on SOM Board (eMMC Flash disabled)

• Set switch SW1-2 = ON
• Insert the SD card into the socket on SMARC SOM CPU board (not the carrier board).
• Press the blue reset button, and then "u-boot" will start. Within 3 seconds, press the space bar on your keyboard in order to stop the auto-boot sequence.
• Note that you will get this message every time "*** Warning - MMC init failed, using default environment" because u-boot environment variables are stored in eMMC Flash (that you disabled)
• At the u-boot prompt ( => ), enter the following commands to boot the board:

  # Manually enter the following commands to boot
=> mmc dev 0 ; fatload mmc 0:1 0x48080000 Image ; fatload mmc 0:1 0x48000000 /r9a07g054l2-smarc.dtb
=> setenv bootargs 'root=/dev/mmcblk0p2 rootwait' ; booti 0x48080000 - 0x48000000

8. Linux Login

• The login will be "root" (no password is needed)
