Official board documentation

Kingfisher(R-Car Starter kit extension board)

Instruction of using M3SK with the Kingfisher board located here http://elinux.org/R-Car/Boards/Kingfisher

Quick Start How To

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

Build Yocto image

Refer to Yocto for steps necessary for making a Yocto image.

Connect 5 V power supply to the board

Use 5 V power supply with a 5.5 mm barrel plug. The power supply should be able to provide 4(Min) ~ 8(Max)Amps.

Note

  • The recommended value is 8 Amps. But, user can use 4 Amps. and 6 Amps. (depends on the use case).

Connect to serial console

Use a microUSB cable to connect the PC to R-Car Starter Kit Pro (M3ULCB) board. CN12 ("CPLD/DEBUG") must be used on Starter Kit side. It is routed to SCIF2 in the R-Car M3 via a FT232 interface converter chip.

On Linux, FT232 driver is included with kernel versions >=2.6.12. Windows driver and sources can be found on FTDI Chip website.

Serial settings are 115200 8N1. Any standard terminal emulator program can be used.

On Linux:

picocom 

sudo picocom -b 115200 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

emap is        : crcrlf,delbs, 

Terminal ready

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

minicom 

sudo minicom -b 115200 -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.

If you encounter problems, make sure that minicom is configured with hardware flow control off. To check this, start minicom with 'minicom -s' then select "Serial port setup" and set 'F - Hardware Flow Control' to 'No'.

Power on the board and go to U-Boot prompt

Short-press SW8 "Power" to switch the board on. Then you should see the following output in the terminal:

Tips

Enabling Automatic POWER ON

By default, the board needs to be powered by pressing the POWER button.
It might be useful for some usage (e.g. automated testing or demo purposes...) to have the board automatic power on when the power is applied.
Hardware modification is necessary to enable such behavior.

According to the page 18 of the board schematic, the PMIC chip has a pin called RSTBMODE which switches between level and edge triggered behavior of the RSTB pin.
By default, the RSTBMODE pin is pulled up by R413, which results in edge-triggered behavior. The PWRON switch is connected to the RSTB pin, and the switch pulls the pin low when pressed.

One way to configure the switch behavior would be driving the RSTBMODE pin low trough another board attached to the ComExpress connector.

However, the schematic also shows that there's an unpopulated footprint for R424, which is a zero ohm resistor for pulling the RSTBMODE low.
A small piece of wire was soldered to the unpopulated footprint of R424 to configure level-triggered mode. Alternatively, simply putting some solder in the unpopulated footprint of R424 is enough.
When power is applied, the RSTB pin is pulled up by the internal pull-up resistor of the PMIC. This results in the PMIC powering up the rest of the board when RSTB has been configured to the level-triggered mode.

Below are a couple of pictures of the location of R424, as well as the actual work that was done to do the modification.

Flashing firmware by using CPLD and Flash Writer

By using CPLD and Flash Writer, it is enabled to flash IPLs(firmware) without changing any switch(SW1/SW6) on R-Car Gen3 Starter Kit.
There are two steps to prepare to write IPLs.
First, reboot R-Car Gen3 Starter Kit in "SCIF Download Mode" via CPLD.
Then, send Flash Writer binary to the board.
After launching Flash Writer, it is possible to write IPLs by using xls2 command.

  • Initial SW1/6 status
    • SW1: ON
    • SW6[all]: ON
How to reboot in "SCIF Download Mode" via CPLD

There are two ways to reboot in "SCIF Download Mode" via CPLD.
It is enough to execute one of the following.

  1. Using U-boot 
    => cpld write 0x00 0x802181fe 
=> cpld write 0x80 0x01
  2. Using cpld-control
    1. Build cpld-control for Host PC 
      $ sudo apt install libftdi-dev
$ make
    2. execute following script. 
      #!/bin/bash
DEV_NAME="/dev/ttyUSB0"
USB_NAME=$( dmesg | grep "attached to ${DEV_NAME##*/}" | tail -1 | grep -oP "(?<=usb )[^:]+" )
SERIAL_NAME=$( dmesg | grep -oP "(?<=usb $USB_NAME: SerialNumber: ).*" | tail -1 )
USB_NAME+=":"$( dmesg | grep -oP "(?<=ftdi_sio $USB_NAME:)[^:]+" | tail -1 )

if [[ "$(id -u)" != "0" ]]; then
    echo Please run as root!
    exit 1
fi

# enter SCIF Download Mode
stty -F $DEV_NAME 115200
./cpld-control -w $SERIAL_NAME 0x00 0x802181FE # For aarch32 flash writer 
# ./cpld-control -w $SERIAL_NAME 0x00 0x8021813E # For aarch64 flash writer
./cpld-control -w $SERIAL_NAME 0x80 0x01
echo "$USB_NAME" > /sys/bus/usb/drivers/ftdi_sio/bind

exit
      Note: Even if reboot in "SCIF Download mode" is succeeded, there is no output on terminal(Ex. minicom).
      Note: for Windows user, python-cpld-control may be used instead of cpld-control.
How to boot Flash Writer
  1. Build Flash Writer 
    $ make AArch=32 clean
$ CROSS_COMPILE=~/gcc-linaro-7.3.1-2018.05-x86_64_arm-eabi/bin/arm-eabi- make AArch=32 BOARD=ULCB
    Note: build option "BOARD=ULCB" and "AArch=32" are required.
    Note: Specific cross compiler is also required(https://github.com/renesas-rcar/flash_writer/blob/rcar_gen3/docs/application-note.md#41-prepare-the-compiler).
  2. Send Flash Writer to the board
    ex) Using minicom
    Type "ctrl+A S" and select upload method "ascii", then choose file for uploading "AArch32_Flash_writer_SCIF_DUMMY_CERT_E6300400_ULCB.mot", after upload finished press any key.
    Then, message like below is shown in terminal
    > Flash writer for R-Car H3/M3/M3N Series Vx.xx <Date>
How to flash IPLs

Please refer to the following pages:

After flashing IPLs , please reboot the board by SW8 to reset CPLD register.
