Quick Start How To

This sections describes steps that are necessary to run a "Hello, World!" application using Yocto build. Both X11 and Wayland are supported.

Build Yocto image

Refer to Yocto for the steps necessary for building a Yocto image.

Connect 12 V power supply to the board

Use 12 V power supply with a 5.5 mm barrel plug. The power supply should be able to provide 5 Amps.

Connect to serial console

Use a microUSB cable to connect the PC to the RZ/G1M Starter Kit board. Use to the CN18 connector on the board. It is routed to SCIF0 in the RZ/G1M via a CP2102 interface converter chip.

On Linux, the CP2102 driver is included with kernel versions >=2.6.12. Windows driver and sources can be found on the Silicon Labs website. NOTE: There have been reports of system freezes caused by the latest version of the driver v6.7.2. The previous version v6.7 has been verified to work correctly.

Serial settings are 38400 8N1. Any standard terminal emulator program can be used.

On Linux:

picocom
sudo picocom -b 38400 DEVICE

replace DEVICE with the proper tty device name, for example /dev/ttyUSB0. Running dmesg | tail can help locating proper device.
After the successful connection, picocom should display:

picocom v1.7

port is        : /dev/ttyUSB0
flowcontrol    : none
baudrate is    : 38400
parity is      : none
databits are   : 8
escape is      : C-a
local echo is  : no
noinit is      : no
noreset is     : no
nolock is      : no
send_cmd is    : sz -vv
receive_cmd is : rz -vv
imap is        : 
omap is        : 
emap is        : crcrlf,delbs,

Terminal ready

Use Ctrl+A, Ctrl+Q to exit picocom.

minicom
sudo minicom -b 38400 -D DEVICE

replace DEVICE with the proper tty device name, for example /dev/ttyUSB0. Running dmesg | tail can help locating proper device.
After the successful connection, minicom should display:

Welcome to minicom 2.6.2

OPTIONS: I18n 
Compiled on Aug  7 2013, 13:32:48.
Port /dev/ttyUSB0

Press CTRL-A Z for help on special keys

Use Ctrl+A, Q to exit minicom.

Power on the board and go to U-Boot prompt

Switch SW26 "Power" to switch the board on. Blue LEDs should lit up. Then you should see the following output in the terminal:

Configure U-Boot to boot over TFTP + NFS or from a micro SD card

Refer to Yocto page for steps necessary for running Yocto.

Bootloader

The RZ/G1M SoC can be booted from various sources. The RZ/G1M Starter Kit board can be booted from QSPI Flash. The board has two SPI Flash memory chips selectable by JP2. In a standard configuration 4MB Flash S25FL032 stores original MiniMonitor firmware (for backup/rescue purposes) and 64 MB FLash S25FL512 stores U-Boot

Boot source JP2 state
QSPI (64MB) 1-2 closed
QSPI (4MB) 2-3 closed

Updating U-Boot

You may want to update U-Boot in case of upgrade or if the board you received does not have the U-Boot flashed into QSPI Flash. Follow these steps carefully to flash U-Boot:

  1. Put the jumper on pins 2 and 3 of JP2. This selects the 4MB SPI Flash with MiniMonitor as a boot device.
    MiniMonitor is loaded via the SPI boot interface of RZ/G1M.
  2. Connect to serial console over microUSB.
    If using picocom, start it with the following command line options:
    sudo picocom -b BAUDRATE --send-cmd "ascii-xfr -vvs" DEVICE
    

    Refer to "Connect to serial console" section for more information.

  3. Switch the board ON or reset it.
    You should see the following output on the console (version numbers can be different):
    SKRZG1M SPI_LOADER(DDR3L-1600) V0.21 2015.11.10
     DEVICE S25FL032
      
    SKRZG1M MiniMonitor SPI_BOOT

     2015.06.04 Ver0.09c ** Program on DRAM (H'40000000-)  ** 
    
    >
    
  4. Execute the ls command:
    ls
    

    You should be able to see the following output:

    Load Program to 64MB Spiflash memory (U16:S25FL512S)
    JP2(SPI_SEL) 1pin-Side! Setting OK? (Push Y key)
    

    MiniMonitor is asking to connect pins 1 and 2 of JP2.

  5. Connect pins 1 and 2 of JP2. This activates 64MB SPI Flash for U-Boot.
  6. Enter y to confirm your setting.
  7. MiniMonitor should ask now:
    Select area(1-2)> 
    

    Answer 2 and Enter.

  8. Mini monitor should display:
    Please Input User Program Start Address :
    

    Enter e6304000 for RZ/G1M and hit Enter.

  9. MiniMonitor should now display:
    Please send ! ('.' & CR stop load)
    

    Send uboot.srec file. It should be available in $WORK/build/tmp/deploy/images/skrzg1m/ folder which is generated by bitbake during Yocto build. Alternatively, you can download it from this site File:G1M U-boot.srec.zip

    picocom

    Use Ctrl+A, Ctrl+S, then select uboot.srec file and hit Enter.
    Transmission should start immediately and the progress counter should be displayed:

  10. If there are some data in writing area, MiniMonitor will display:
    SPI Data Clear(H'FF) Check :H'0080000-00BFFFF Clear OK?(y/n)
    

    You can safely input "y" to override area 2 of 64MB SPI Flash.

  11. After writing is complete, MiniMonitor should display
    SPI Data Clear(H'FF) Check :H'00080000-000BFFFF Erasing..Erase Completed 
    SAVE SPI-FLASH....... complete!
    -- Save (Program Start Address & Size ) -----

FAQ

How do I change/update the MAC address of the Ethernet interface?

In U-boot command line type:

=> env delete -f ethaddr                  
=> setenv ethaddr 2e:09:0a:00:xx:xx
=> saveenv

You should see the output

Saving Environment to SPI Flash...
SF: Detected S25FL512S with page size 256 KiB, total 64 MiB
Erasing SPI flash...Writing to SPI flash...done

The original (default) MAC address can be found on the label on top of RJ45 connector.

How do I connect an external LVDS display with touchscreen?

See an example for Boundary Devices BD101LCC1 display.

Which operating systems/distributions can be used with the RZ/G1M Starter Kit board?

  • Yocto 1.6.1 Linux (kernel 3.10 LTSI)
  • Yocto 2.0 Linux (kernel 4.4)
