1 Overview

This section describes the background and scope of application for configuring devices for SSD booting on the ED-IPC2100 Series, ED-IPC2600 Series, ED-IPC3020, ED-HMI2120, and ED-HMI3020.

1.1 Background

Traditionally, the Raspberry Pi has used SD cards as boot and storage media. While SD cards have the advantage of being easily accessible and inexpensive, they typically do not perform as well as Solid State Drives (SSDs in terms of read/write speed and durability. With the price of SSDs dropping and the performance of USB interfaces improving, using SSDs to boot and run the Raspberry Pi is a preferred option that can improve performance and reliability.

Currently our devices are mainly booted via eMMc or SD card. For products that have reserved SSD interface, we support to configure the device to boot from SSD by modifying the boot method of the device.

1.2 Scope

This application applies to ED-IPC2100 series, ED-IPC2600 series, ED-IPC3020, ED-HMI2120, and ED-HMI3020.

2 Application Guidelines

This section describes the procedure to configure booting from SSD on ED-IPC2100 series, ED-IPC2600 series, ED-HMI2120, ED-IPC3020, and ED-HMI3020.

2.2 SSD Flash

Introduces the specifics of flashing an SSD on a device via the Raspberry Pi Image tool.

Prerequisite:

  • The device has booted the system normally via the SD card and the SSD has been installed to the device.
  • The image file to be flashed has been acquired.
  • A Windows PC has been prepared.

WARNING

For SSD installation operation, please refer to the user's manual of the corresponding device!

Operational Steps:

Take Windows system as an example to illustrate the operation steps.

  1. Decompress the downloaded image (.zip file) to obtain the .img file, and store it in a specified directory on the local Windows PC, e.g., Desktop. 2.
  2. Use the SCP command on the Windows PC to copy the image file (.img) to the device.

a Press Windows+R at the same time to open the Run pane, type cmd, and press Enter to open the command pane. b Execute the following command to copy the image file (.img) to the pi directory of the device.

scp "Desktop\2024-04-02-ed-HMI3020-101C_raspios-bookworm-arm64.img" pi@192.168.168.229:~
image
  • Desktop\2024-04-02-ed-HMI3020-101C_raspios-bookworm-arm64.img: indicates the path where the file is stored in the Windows computer.
  • pi: indicates the directory of the device (i.e., the path where the image file is stored after it is copied)
  • 192.168.168.229: the IP address of the device.
  1. View the image file in the pi directory of the device after the copy is complete.

  1. Close the Raspberry Pi Imager.

2.3 Configuring the boot sequence

There are different ways to configure the startup sequence corresponding to different models, which are explained below according to two categories.

2.3.1 Modifying the boot sequence on ED-HMI3020 and ED-IPC3020

Change the startup order in raspi-config.

Change the startup order in raspi-config.

Prerequisites:

  • The device has booted normally from the SD card.
  • The SSD flash has been completed.

Operation steps:

  1. In the command pane, execute the following commands sequentially to upgrade the system.
sudo apt update
sudo apt upgrade
  1. Execute the following command to open the raspi-config interface.
sudo raspi-config
image-20240523160744720
  1. In raspi-config interface, press “↓” key to select “Advanced Options”, Enter key to confirm.
