Getting Started
1. Download the Linux BSP : Download the Linux BSP from renesas.com. More information can be found here
2. Build Environment : To build the BSP, you will need a Linux PC running Ubuntu 20.04.
3. Build the BSP : The instructions for building the BSP are located in the "Release Note" document that can also be downloaded from renesas.com .
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-rzg2l # Copy the Linux kernel and Device Tree to partition 1 $ sudo cp -v Image /media/$USER/RZ_FAT $ sudo cp -v r9a07g044l2-smarc.dtb /media/$USER/RZ_FAT # Copy and expand the Root File System to partition 2 $ sudo tar -xvf core-image-minimal-smarc-rzg2l.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/G2L.
- Set the switches on the SOM board to what you want to use.
- Note that the SD Card slot on the Carrier board will always work because it uses a separate peripheral channel on the RZ/G2L.
- On the SOM (CPU) board, there is a little switch (SW1) by the SD card socket.
SOM board uses SD Card socket SOM board uses eMMC Flash SW1-1 = ON SW1-1 = ON SW1-2 = ON SW1-2 = OFF +-----+ +-----+ | ON | | ON | | = = | | = | | | | = | | 1 2 | | 1 2 | +-----+ +-----+
7-1. Boot the Board using eMMC Flash on SOM board
- Set switch SW1 ON,OFF
- The boot loader (u-boot) by default will try to boot from eMMC after 3 seconds.
- Press the blue reset button and wait.
7-2. Boot the Board using SD Card on SOM board
- Set switch SW1 ON,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.
- At the u-boot prompt ( => ), enter the following commands to boot the board:
=> mmc dev 0 ; fatload mmc 0:1 0x48080000 Image ; fatload mmc 0:1 0x48000000 /r9a07g044l2-smarc.dtb => setenv bootargs 'root=/dev/mmcblk0p2 rootwait' ; booti 0x48080000 - 0x48000000
7-3. Boot the Board using SD Card on Carrier board
- 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.
- At the u-boot prompt ( => ), enter the following commands to boot the board:
=> mmc dev 1 ; fatload mmc 1:1 0x48080000 Image ; fatload mmc 1:1 0x48000000 /r9a07g044l2-smarc.dtb => setenv bootargs 'root=/dev/mmcblk1p2 rootwait' ; booti 0x48080000 - 0x48000000
8. Linux Login
- The login will be "root" (no password is needed)
Board Setup Information
Board Operation Information
Power ON ● Connect USB-PD Power Charger to USB Type-C Connector. Then LED1(VBUS PWR On) and LED3(Module PWR On) lights up. ● Press SW9 to turn on the power. Then LED4(Carrier PWR On) lights up. |
Debug Serial (Console Output) ● Debug serial uses CN14. The baud rate is 115200bps. ● Since the serial-USB conversion IC is not always powered, the Windows PC will recognize it after the power switch is turned on. ● If it is not recognized by your Windows PC, please install the driver�https://www.ftdichip.com/Drivers/VCP.htm |
