Getting Started Appendix

This page explains the additional information of Getting Started.

A1. Setup for eMMC Bootloader

This section explains how to setup the board for eMMC Bootloader.

Note This step is required only when starting the AI SDK or when using the new version of AI SDK.
If you have already setup the microSD card and the bootloader written in eMMC on the board, skip this step and proceed to the next step (Step7:2. Deploy Application to the Board in Getting Started).

Follow the instruction below to setup the board.

Note Explanation in this step is for eMMC Bootloader, which requires Windows PC as serial communication console.

1. Install Terminal Emulator

Note If you have already installed terminal emulator, skip this step and proceed to next procedure.
1. Install following software on Windows PC to be used as serial communication console.
  - Terminal emulator
    - Operating Environment: Tera Term
2. Install the serial port driver

Note If you have already installed the serial port driver, skip this step and proceed to next procedure.
The serial communication between Windows PC and RZ/V2L EVK requires following driver.
https://ftdichip.com/drivers/vcp-drivers/
1. Download the software "Virtual COM port (VCP) driver" from the windows version "setup executable" on the download page and extract it.
2. Run the *.exe file extracted to install the serial port driver.

3. Write bootloaders to eMMC on the board

Copy following files in ${WORK}/board_setup/eMMC/bootloader to your Windows PC.
- Flash_Writer_SCIF_RZV2L_SMARC _PMIC_DDR4_2GB_1PCS.mot
- bl2_bp-smarc-rzv2l_pmic.srec
- fip-smarc-rzv2l_pmic.srec

Connect Windows PC and Board via Serial to MicroUSB Cable.

Change SW1 and SW11 setting (see the figure below).

Connect the power cable to CN6 on the Board.

Press and hold the power button (SW9) for 1 second to turn on the power.

On Windows PC, open the terminal emulator. Here, we use Tera Term as an example.

Select "File" > "New Connection" and select "Serial" port as shown below.

Open the configuration window from the "Setup">"Terminal" and change the setting as follows.

Item Value

New-line Receive: Auto

Transmit: CR

Item	Value
New-line	Receive: Auto
	Transmit: CR

Open the configuration window from the "Setup">"Serial port" and change the setting as follows.

Item	Value
Baud rate	115200
Data	8bit
Parity	none
Stop	1bit
Flow control	none
Transmit delay	0msec/char

Press the reset button (SW10) and following message will be displayed on the terminal.

Power-off the board by pressing the power button (SW9) for 2 seconds to change SW11 for booting the board.

4. Setup U-boot setting
Follow the procedure below to set the booting configuration of the board.
1. Insert the microSD card to the Board.
  Note Use the microSD card slot CN10 as shown in the figure.
2. Change SW1 and SW11 setting as shown in the right figure.
3. Connect the Board and Windows PC by the USB Serial to Micro USB cable.
4. Connect the power cable to the Board.
5. Press power button for 1 second to turn on the board.
6. Open the terminal emulator, i.e., Tera Term, and connect with COMS port.
  Note When using Tera Term, change the configuration as explained in Write bootloaders to eMMC on the board.
7. On the terminal emulator, keep pressing ENTER key and on the board, press reset button.
1. U-boot console will be activated.
2. Run the following commands to set the booting configuration.
  env default -a setenv bootargs 'root=/dev/mmcblk1p2 rootwait' setenv bootcmd 'mmc dev 1;fatload mmc 1:1 0x48080000 Image-smarc-rzv2l.bin; fatload mmc 1:1 0x48000000 Image-r9a07g054l2-smarc.dtb; booti 0x48080000 - 0x48000000' saveenv boot

Refer to the Step 7: 2. Deploy Application to the Board in RZ/V2L EVK Getting Started.

A2. Format SD card

When writing the necessary files for the board, microSD card needs to have appropriate format.
Note that you need to run this procedure only once as long as you use the same microSD card.

Follow the instruction below to format the microSD card partitions.

Preparation

Click the button This section contains both eSD and eMMC Bootloader explanation.
Please click the button below to update the explanation according to your bootloader interface.

eSD Bootloader eMMC Bootloader

For eSD eSD explanation will be shown in this style if you click "eSD Bootloader" button above.

For eMMC eMMC explanation will be shown in this style if you click "eMMC Bootloader" button above.

Check the SD card connection

Before inserting the microSD card to your Linux PC, open the terminal on Linux PC and run the following command to check the devices without microSD card.

lsblk

Following is the example output.

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 30.9G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 30.3G 0 part /
sr0 11:0 1 1024M 0 rom

Insert the microSD card to your Linux PC and run the following command again.
```
lsblk
```

Check the output and confirm the name appeared.
This would be your microSD card device name.
- Following is the example output.
```
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 30.9G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 30.3G 0 part /
sdb 8:16 1 29.7G 0 disk
└─sdb1 8:17 1 29.7G 0 part
sr0 11:0 1 1024M 0 rom
```
- In this case, followings are your microSD card configuration.
  - /dev/sdb: The device name for the entire microSD card.
  - /dev/sdb1: The paritition name in microSD card. There may be multiple sdb* depending on the microSD card.
  Warning Be careful not to use the name of other device since it may destruct your computer filesystem.

Run the following command to check the automatically mounted microSD card partitions.
```
df
```

Check the output and find the mount point, which is "/media/user/A8D3-393D" in the following example.

Filesystem 1K-blocks Used Available Use% Mounted on
udev 745652 0 745652 0% /dev
:
snip
:
/dev/sdb1 511720 4904 506816 1% /media/user/A8D3-393B

Unmount the automatically mounted partitions.
```
sudo umount /media/user/A8D3-393B
```
- If there are more than one partitions on microSD card, unmount all partitions.

Create SD card partition

Run fdisk command as shown below to change the partition table according to the following table.

For eSD

Type/Number	Size	Type of Filesystem	Contents
Primary #1	500MB (minimum 128MB)	Ext4	Linux kernel Device tree
Primary #2	All remaining	Ext4	Root filesystem

Note "Type of Filesystem" of "Primary #1 Linux kernel and Device tree" Contents is Ext4.

For eMMC

Type/Number	Size	Type of Filesystem	Contents
Primary #1	500MB (minimum 128MB)	FAT32	Linux kernel Device tree
Primary #2	All remaining	Ext4	Root filesystem

Note "Type of Filesystem" of "Primary #1 Linux kernel and Device tree" Contents is FAT32.

sudo fdisk /dev/sdb

Warning Use device name. Do NOT use partition name such as /dev/sdb1.
