RNX-RZG2UL-OSM Programming Images
Overview
For a complete Linux System, the CPU Module RNX-RZG2UL-OSM requires the following images:
- Boot Loader stage 2 (BL2) Trusted Boot Firmware with boot parameters block
- Boot Loader stage 3-1 (BL3-1) EL3 Runtime Firmware
- U-BOOT
- Linux Kernel with Device Tree Blob
- RootFS - root file system
The bootloaders (BL2, BL3 and U-BOOT) and the Linux Kernel can be programmed on the QSPI Flash or on the eMMC.
The RoorFS can be programmed on the eMMC or on a SD card (J41 on the carrier board).
More information can be found in "r01us0616ej0100-rz-g(Linux Start-up Guide RZG2L,LC,UL).pdf" which is part of
the Renesas RZG Verified Linux Package:
or
After successful YOCTO building, all these images are available in tmp/deploy/images/rnx-rzg2ul-osm:

| Flash_Writer_SCIF_RZG2UL_SMARC_DDR4_1GB_1PCS.mot | Renesas Flash Writer |
Alternatively, for development purpose, the images can be built standalone:
- RNX-RZG2UL-OSM_ARM_Trusted_Firmware
- RNX-RZG2UL-OSM_U-Boot
- RNX-RZG2UL-OSM_Linux
- RNX-RZG2UL-OSM_Flash_Writer
The images can be programmed using the Renesas Flash Writer or PEEDI JTAG Flash Programmer.
Setting Boot mode
On the carrier board, set the boot mode to "SCIF Download mode".
| J31, pin 1-2 | J31, pin 3-4 | |
|---|---|---|
| SCIF Download mode | close | open |
| QSPI Boot mode | open | close |
| eMMC Boot mode | close | close |

Programming QSPI Flash using Renesas Flash Writer
Serial terminal connection
A serial terminal connection through USB to UART bridge is required.
- Connect a USB Type-microAB cable to J3 (UART DBG).
- Start a terminal app (for example minicom) and configure to use the second FTDI port.
- After power up, the CPU reports:
(C) Renesas Electronics Corp. -- Load Program to System RAM --------------- please send !
Programming Bootloaders
Download Flash Writer to RAM
In minicom, press Ctrl-A S and then select "ascii" upload protocol.
Select the file tmp/deploy/images/rnx-rzg2ul-osm/Flash_Writer_SCIF_RZG2UL_SMARC_DDR4_1GB_1PCS.mot
After successfully downloading the binary, Flash Writer starts automatically and shows a message
like below on the terminal.
DDR init done.

Flash writer for RZ/G2 Series V1.06 Aug.10,2022
Product Code : RZ/G2UL Type1
>
Programming
For the boot operation, two bootloader files need to be written to the target board:
- tmp/deploy/images/rnx-rzg2ul-osm/bl2_bp-rnx-rzg2ul-osm.srec (BL2 bootloader + boot parameters)
- tmp/deploy/images/rnx-rzg2ul-osm/fip-rnx-rzg2ul-osm.srec (BL3 + U-BOOT)
“XLS2” command of Flash Writer is used to write bootloader binary files. This command receives binary data from the serial port and writes the data to a specified address of the Flash ROM with information where the data should be loaded on the address of the main memory.
>xls2 ===== Qspi writing of RZ/G2 Board Command ============= Load Program to Spiflash Writes to any of SPI address. Dialog : AT25QL128A Program Top Address & Qspi Save Address ===== Please Input Program Top Address ============ Please Input : H'11E00

- Send the data of bl2_bp-rnx-rzg2ul-osm.srec from terminal software after the message “please send !” is shown.
After successfully download the binary, messages like below are shown on the terminal.
OK SAVE SPI-FLASH....... ======= Qspi Save Information ================= SpiFlashMemory Stat Address : H'00000000 SpiFlashMemory End Address : H'0000CA38 ===========================================================
Next, write another loader file by using XLS2 command again.

- Send the data of fip-rnx-rzg2ul-osm.srec from terminal software after the message "please send !" is shown.

Write Linux Kernel and RootFS to a uSD card
The simplest way to write Linux Kernel and RootFS to a SD card is using the bmaptool:
$ sudo bmaptool copy tmp/deploy/images/rnx-rzg2ul-osm/core-image-bsp-rnx-rzg2ul-osm.wic.gz /dev/sdX
Boot log
- Select QSPI Boot mode and reset the board:
