Deploy Binaries

The following binaries are used for the Network boot mode:

• bl2_bp_spi-smarc-rzg3e.srec: Bootloader for SPI memory that initializes the hardware components needed to run U-Boot.
• fip-smarc-rzg3e.srec: Firmware package that bundles U-Boot and other secure components into one boot image.
• Flash_Writer_SCIF_RZG3E_EVK_LPDDR4X.mot: Software that is loaded into the RZ/G3Es RAM to write bootloader files into flash memory.

core-image-minimalcore-image-weston

• core-image-minimal-smarc-rzg3e.rootfs.tar.gz: Compressed Linux disk image containing the rootfs (Linux kernel, drivers, applications and system configurations).

• core-image-weston-smarc-rzg3e.rootfs.tar.gz: Compressed Linux disk image containing the rootfs (Linux kernel, drivers, applications and system configurations).

By using the Network boot mode, the bootloaders need to be manually flashed to the board.

Setup U-Boot Environment

U-Boot Hardware Setup

1. Start up a serial terminal connection (e.g. TeraTerm or Minicom) on Host PC, making sure the correct COM port and settings are used.

   Variable	Value
   Baud rate	115200 bps
   Data	8 bit

   Stop	1 bit
   Flow control	none

2. Power ON the board by pressing the POWER button for at least 1 second until the CARRIER ON LED lights up.
   The CARRIER ON LED is located above the POWER button.

3. Press any key to stop the autoboot within 3 seconds of U-Boot starting.
   If U-Boot attempts to boot, press the RESET button and try again.

4. Set up the U-Boot environment.

   env default -a
   setenv ipaddr '192.168.1.2'
   setenv serverip '192.168.1.1'
   setenv ethaddr '00:11:22:33:44:55'
   setenv bootcmd 'tftp 0x48080000 rzg3e/boot/Image; tftp 0x48000000 rzg3e/boot/r9a09g047e57-smarc.dtb; booti 0x48080000 - 0x48000000'
   setenv bootargs 'console=ttySC0,115200 debug rootwait root=/dev/nfs rw nfsroot=192.168.1.1:/tftpboot/rzg3e,v3 ip=192.168.1.2:::::eth0:off'
   saveenv
   

   Note

   The IP/MAC addresses should be set up according to the Linux Host PCs environment.

5. Power OFF the board by pressing the POWER button for at least 1 second until the CARRIER ON LED turns off.
   The CARRIER ON LED is located above the POWER button.

Boot The Board

1. Whilst the board is not powered, confirm that following hardware configuration is being used.
