9. According to the prompt, select the OS file from the user-defined path and return to the main page.
10. Click "CHOOSE STORAGE", select the default device in the "Storage" interface, and return to the main page.
11. Click "NEXT". In the pop-up "Use OS customization?" pane, select "NO".
12. Select "YES" in the pop-up "Warning" pane to start writing the image.
13. After the OS writing is completed, the file will be verified.
14. After verification is completed, click "CONTINUE" in the "Write Successful" pop-up box.
15. Close Raspberry Pi Imager, remove the USB cable, and power on the device again.

6.3 Installing Firmware Package

After flashing the eMMC on the ED-IPC2400 Series, configure the system by adding the edatec apt source and installing the firmware package to ensure proper system operation. The following is an example for Debian 12 (bookworm) desktop version and ED-IPC2410.

Preparation:

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

Steps:

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

curl -s https://apt.edatec.cn/bsp/ed-install.sh | sudo bash -s ipc2410

TIP: If the product models are ED-IPC2420 and ED-IPC2430, the firmware package names are ipc2420 and ipc2430, respectively.

2. After the installation is complete, the system automatically reboots.
3. Execute the following command to check if the firmware package was installed successfully:

dpkg -l | grep ed-

The output will indicate if the firmware package has been installed successfully.

TIP: If the wrong firmware package was installed, it can be deleted using sudo apt-get --purge remove package, where "package" is the package name.
