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 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 TBD Amps.
Connect to serial console
Use a microUSB cable to connect the PC to R-Car E2 SILK board. CN13 ("DEBUG") must be used on SILK side. It is routed to SCIF2 in the R-Car E2 via a CP2102 interface converter chip.
On Linux, CP2102 driver is included with kernel versions >=2.6.12. Windows driver and sources can be found on Silicon Labs website.
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
Short-press SW11 "Power" to switch the board on. Orange LED should lit up indicating that board has 3.3V power. Then you should see the following output in the terminal:
SILK SPI_LOADER V0.07c 2014.10.20
DEVICE S25FL512
U-Boot 2013.01.01-g74b16ba-dirty (Dec 23 2014 - 15:31:50)

Hit any key to stop autoboot: 3
Quickly hit any key to get into U-boot command prompt. Use SW5 Reset to reboot the board when necessary.
You should see the following:
Hit any key to stop autoboot: 0 =>
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
R-Car E2 SoC can be booted from various sources. SILK board is booted from QSPI Flash device. SILK has two SPI Flash memory chips selectable by SW9. In a standard configuration 4MB Flash S25FL032 stores original MiniMonitor firmware (for backup/rescue purposes) and 64 MB FLash S25FL512 stores MiniMonitor (QSPI Loader) and U-Boot (main storage).
Updating U-Boot using MiniMonitor
You may want to update U-Boot in case of upgrade or if the board you received does not have the U-Boot flashed. Follow these steps carefully to flash U-Boot:
-
Set SW9 to pin 3 side. This selects 4MB SPI Flash with MiniMonitor as a boot device.
MiniMonitor is loaded via SPI boot interface of R-Car E2. -
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.
-
Switch the board ON or reset it.
You should see the following output on the console (version numbers can be different):SILK SPI_LOADER V0.05 2014.08.14 DEVICE S25FL032 SILK MiniMonitor SPI_BOOT Work memory DRAM (H'40200000-) 2014.08.15 Ver0.05 ** Program on DRAM (H'40000000-) ** >
-
Execute the ls command:
ls
You should be able to see the following output:
Load Program to Spiflash memory (U6:S25FL512S) SW9 1pin-Side! Setting OK? (Push Y key)
MiniMonitor is asking to flip SW9 to 1 pin side.
-
Switch SW9 to 1 pin side. This activates 64MB SPI Flash for U-Boot.
-
Enter y to confirm your setting.
-
MiniMonitor should ask now:
Select area(1-2)>
Answer 2 and Enter.
-
Mini monitor should display:
Please Input User Program Start Address :
Enter e6304000 for R-Car E2 and hit Enter.
-
MiniMonitor should now display:
Please send ! ('.' & CR stop load)Send uboot.srec file. It should be available in $WORK/build/tmp/deploy/images/silk/ folder which is generated by bitbake during Yocto build. Alternatively, you can download it from this site File:R-Car SILK 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:*** file: /data/Renesas/SILK/build/tmp/deploy/images/silk/u-boot.srec ascii-xfr -vvs /data/Renesas/SILK/build/tmp/deploy/images/silk/u-boot.srec ASCII upload of "/data/Renesas/SILK/build/tmp/deploy/images/silk/u-boot.srec" 15.0 Kbytes transferred at 3732 CPS...
minicom
Use Ctrl+A, S, choose ascii, then locate uboot.srec file and hit Enter. Transmission should start immediately and the progress counter should be displayed:

-
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.
-
After writing is complete, MiniMonitor should display

Done. *** exit status: 0 SPI Data Clear(H'FF) Check : OK SAVE SPI-FLASH....... complete! -- Save (Program Start Address & Size ) ----- SPI Data Clear(H'FF):H'040000-07FFFF Erasing..Erase Completed SAVE SPI-FLASH....... complete! ========== SPI Flash Sector1 Save Information ========= Program Start Address : H'E6304000 Program Size : H'00036D44 =========================================================
-
Reboot R-Car E2 SILK board by pressing SW5 "Reset" button. Leave SW9 on 1 pin side.
You should see U-Boot prompt now.SILK SPI_LOADER V0.05 2014.08.14 DEVICE S25FL512 U-Boot 2013.01.01-g74b16ba-dirty (Dec 10 2014 - 16:16:57) CPU: Renesas Electronics R8A7794 rev 1.0 Board: Silk Board DRAM: 1 GiB MMC: sh_mmcif: 0, sh-sdhi: 1 SF: Detected S25FL512S with page size 256 KiB, total 64 MiB In: serial Out: serial Err: serial Net: sh_eth Hit any key to stop autoboot: 3
Flashing QSPI loader using MiniMonitor
You may want to flash QSPI loader in case you board does not have it pre-loaded. Follow these steps carefully to flash QSPI loader:
-
Set SW9 to pin 3 side. This selects 4MB SPI Flash with MiniMonitor as a boot device.
MiniMonitor is loaded via SPI boot interface of R-Car E2. -
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.
