5 Installing OS (optional)

The device is shipped with an operating system by default. If the OS is corrupted during use or the user needs to replace the OS, it is necessary to re-download the appropriate system image and install it. Our company supports to install the OS by installing the standard Raspberry Pi OS first, and then install the Firmware package.

The following section describes the specific operations of image download, eMMC flashing and installation of Firmware packages.

5.1 Downloading OS File

You can download the corresponding official Raspberry Pi OS file according to your actual needs, the download path is listed below:

5.2 Flashing to eMMC

It is recommended to use the Raspberry Pi official tools. The download paths are as follows:

• Raspberry Pi Imager: https://downloads.raspberrypi.org/imager/imager_latest.exe
• SD Card Formatter: https://www.sdcardformatter.com/download/
• Rpiboot: https://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe

Preparation:

• The downloading and installation of the official tools to the computer have been completed.
• A USB-A to USB-A cable has been prepared.
• The OS file has been obtained.

Steps:

The steps are described using Windows system as an example.

1. Connect the power cable and USB flashing cable (USB-A to USB-A cable).

• Connecting to USB flashing cable: One end connects to the USB 3.0 port on the lower side of the ED-SBC2300 Dual Layer USB 3.0 connector (red box location as shown below) and the other end connects to the USB port on the PC.

• Connecting to power cord: One end is connected to the DC jack connector on the device, and the other end is connected to the external power supply.

2. Short Pin 2 and Pin 3 of RPI_BOOT interface, for specific information refer to 1.3.2.11 RPI_BOOT.

15. After the OS writing is completed, the file will be verified.

16. After the verification is completed, click “CONTINUE” in the pop-up “Write Successful” box.

17. Close Raspberry Pi Imager, remove USB cable and power on the device again.

5.3 Installing Firmware Package

After you have finished flashing to eMMC on ED-SBC2300, you need to configure the system by adding edatec apt source and installing firmware package to make the system work. The following is an example of Debian 12 (bookworm) desktop version.

Preparation:

• The flashing to eMMC of the Raspberry Pi standard OS (bookworm) has been completed.
• The device has booted normally and the relevant boot configuration has been completed.

Steps:：

1. After the device starts normally, execute the following commands in the command pane to add the edatec apt source and installing firmware package.

curl -s https://apt.edatec.cn/bsp/ed-install.sh | sudo bash -s sbc231x

2. After the installation is complete, the system automatically will reboot.

3. Execute the following command to check whether the firmware package is installed successfully.

dpkg -l | grep ed-

The result in the picture below indicates that the firmware package has been installed successfully.

TIP

If you have installed the wrong firmware package, you can execute sudo apt-get --purge remove package to delete it, where “package” is the package name.
