Update firmware (bootloaders) on EVK¶

When you use QSPI boot mode or eMMC boot mode, you should update firmware (bootloaders). This page describes how to write flash writer and bootloaders. To write flash writer and bootloaders, you need to connect your PC to the EVK with a USB serial cable. See "Setup EVK's peripheral". And The following tools are used in this instructions. Please install them to your PC in advance.

For information about how to use use QSPI boot, see Boot Linux from microSD card. And for information about how to use eMMC boot, refer to RZ/G2L, RZ/G2LC and RZ/G2UL-EVKIT Linux Start-up Guide.

1. Set boot mode to SCIF download mode¶

Turn off the power of EVK, then set the SW11 as follows.

2. Configure terminal software¶

Configure the setting of serial communication on terminal software as follows:

• Speed: 115200 bps
• Data: 8bit
• Parity: None
• Stop bit: 1 bit
• Flow control: None

3. Prepare flash writer and bootloaders¶

The flash writer and the bootloaders are stored in the pre-built binaries pacakge of the HMI SDK. See file contents.

Unzip the pre-built binaries package to pick up flash write and bootloaders as follows:

unzip pre-built-binary_rzg2l_hmi-sdk_v*.zip

unzip pre-built-binary_rzg2lc_hmi-sdk_v*.zip

unzip pre-built-binary_rzg2ul_hmi-sdk_v*.zip

4. Download flash writer to RAM¶

Turn on the power of the EVK by pressing SW9. The messages below are shown on the terminal.

 SCIF Download mode
 (C) Renesas Electronics Corp.
-- Load Program to System RAM ---------------
please send !

Send an image of flash writer using terminal software after the message "please send !" is shown.

After successfully downloading the image, the flash writer starts automatically and shows a message like below on the terminal.

Flash writer for RZ/G2 Series V1.06 Aug.10,2022                                                    
 Product Code : RZ/G2UL Type1   
>

5. Write the bootloaders¶

5-1. Change baud rate of serial port¶

Before writing the loader files, change the flash writer transfer rate from default (115200bps) to high speed (921600bps) with "SUP" command.

SUP

After the "SUP" command, change the serial communication protocol speed from 115200bps to 921600bps on the terminal software.

5-2. Write bl2 file¶

Execute "XLS2" command to write boot loader binary files.

XLS2

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. Set the following addresses respectively.

• Address to load to RAM: H'11E00
• Address to save to ROM: H'00000

For example:

>XLS2

Writes to any of SPI address.

===== Please Input Program Top Address ============                                                
  Please Input : H'11E00                                                                           

===== Please Input Qspi Save Address ===                                                           
  Please Input : H'00000

please send ! ('.' & CR stop load)

Send the data of "bl2_bp-smarc-rzg2*.srec" from terminal software in the same way as the flash writer after the message "please send !" is shown. For the actual file name of bl2 file, see 3. Prepare flash writer and bootloaders.

In the case that the following message is shown, enter 'y'.

SPI Data Clear(H'FF) Check :H'00000000-0000FFFF,Clear OK?(y/n)

After writing the data is completed, the following messages like below are shown on the terminal.

5-3. Write fip file¶

Execute "XLS2" command to write fip file.

XLS2

Set the following addresses respectively for the fip file.

• Address to load to RAM: H'00000
• Address to save to ROM: H'1D200

For example:

>XLS2
