Overview

This application note explains how to install the images built by the Emcraft software distribution procedure to the Renesas RZ/V2H target.

Installation Workflows

Setting Up Host for Installation

The following tool are required to be installed on the host for performing the target programming procedure:

A serial terminal emulator application with the “ASCII Send” capability (eg TeraTerm, picocom, etc.).
zstd (de)compression tool.
unzip decompression tool.

Extract the release archive to a separate directory on the host. The files from the archive will be used in follow up sections:

[user@localhost ~] unzip 0.0.1-34-12150405-rzv2h.zip
[user@localhost ~] ls -l

Installing U-Boot Images to the Board’s QSPI Flash

Use the following step-wise procedure to install the images to the Renesas RZ/V2H target:

Power off the target board.
On the target CPU Module, set the SW1.4-5 switches to Off On.
Power on the target board.

In the TeraTerm window, observe the Download Mode messages, as follows:

SCI Download mode (Normal SCI boot)
-- Load program to SRAM ----------------

In the TeraTerm window, select the Send file… command and use it open the Flash_Writer_SCIF_RZV2H_DEV_INTERNAL_MEMORY.mot image.
Note: When programming on Linux, use the ascii-xfr -s -vv command to send the files, eg:
```
$ picocom -b 115200 /dev/ttyUSB0 -l --send-cmd="ascii-xfr -s -vv"
```
After loading the image, you should have the following prompt in the serial console window:
```
Flash writer for RZ/V2H Series V0.60 Jan.26,2023
Product Code : RZ/V2H
>
```

Enter the XLS2 command:

Flash writer for RZ/V2H Series V0.60 Jan.26,2023
Product Code : RZ/V2H
>XLS2

Enter the Program Top address and QSPI Save address as below:

Flash writer for RZ/V2H Series V0.60 Jan.26,2023
Product Code : RZ/V2H
>XLS2
==== Qspi writing of RZ/G2 Board Command =============
Load Program to Spiflash
Writes to any of SPI address.
Program size & Qspi Save Address
===== Please Input Program Top Address ============
Please Input : H'8101E00
===== Please Input Qspi Save Address ===
Please Input : H’0000
please send ! ('.' & CR stop load)

In the TeraTerm window, run the Send file… command on the bl2_bp_spi-rzv2h-evk-alpha-emc.srec image.

Repeat the loading for the fip-rzv2h-evk-alpha-emc.srec image using the Program Top address and QSPI Save address as below:

Flash writer for RZ/V2H Series V0.60 Jan.26,2023
Product Code : RZ/V2H
>XLS2
===== Qspi writing of RZ/G2 Board Command =============
Load Program to Spiflash
Writes to any of SPI address.
Program size & Qspi Save Address
===== Please Input Program Top Address ============
Please Input : H’0000
===== Please Input Qspi Save Address ===
Please Input : H’64000
please send ! ('.' & CR stop load)

After sending the images, turn the target board off.
On the target CPU Module, change the SW1.4-5 switches to Off Off.
Power on the target board.

Verify the that U-Boot messages are printed, as follows:

psl@VL-4006:~$ zstd -dc image-ubuntu-desktop-rzv2h-evk-alpha-emc-20231123.wic.zst | sudo dd of=/dev/sda bs=8M conv=fdatasync
psl@VL-4006:~$ sudo resize2fs /dev/sda2

Insert SD card to the RZ/V2H EVK board.
Power on the board.

Check that SD card (/dev/mmcblk1p2) is used as the root device:

user@rzv2hevkalpha:~$ cat /proc/cmdline 
rw rootwait earlycon root=/dev/mmcblk1p2

Installing to eMMC

Boot the board from SD card (see above).

Note the board IP address (192.168.0.204):
