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 4 Amps.

Connect to serial console
Use a microUSB cable to connect the PC to RZ/G1E Starter Kit board. The the CN13 ("DEBUG") connector on the board. It is routed to SCIF2 in the RZ/G1E 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 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

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

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: SKRZG1E SPI_LOADER (DDR1333) V0.12 2015.11.10 DEVICE S25FL512 U-Boot 2013.01.01-gcb82c56-dirty (Dec 14 2015 - 10:45:39)

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
The RZ/G1E SoC can be booted from various sources. The RZ/G1E Starter Kit board is booted from QSPI Flash. The board has two SPI Flash memory chips selectable by SW9. In a standard configuration the 4MB Flash S25FL032 stores the original MiniMonitor firmware (for backup/rescue purposes) and the 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 the SPI boot interface of RZ/G1E.   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): SKRZG1E SPI_LOADER (DDR1333) V0.12 2015.11.10 DEVICE S25FL032 SKRZG1E MiniMonitor SPI_BOOT Work memory DRAM (H'40200000-) 2015.11.10 Ver0.05a ** Program on DRAM (H'40000000-) **

(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 RZ/G1E and hit Enter. </li>  MiniMonitor should now display: Please send !
