6.3 Install Firmware Package

After flashing the standard Raspberry Pi OS onto the ED-HMI2630-101C, you need to add the edatec apt source and install the firmware package to configure the system for normal use. The following describes the process using Debian 12 (bookworm) Desktop version as an example.

Prerequisites:

• The Raspberry Pi standard bookworm image has been successfully flashed.
• The device has booted normally, and relevant startup configurations have been completed.

Operation Steps:

1. After the device boots normally, execute the following commands in the command window to add the edatec apt source and install the Firmware package:

curl -s https://apt.edatec.cn/bsp/ed-install.sh | sudo bash -s hmi2630_101c

After installation is complete, the device will automatically restart.

3. Execute the following command to check if the firmware package has been installed successfully:

dpkg -l | grep ed-

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

Note: If you have installed the wrong firmware package, you can execute sudo apt-get --purge remove package to uninstall it, where 'package' is the name of the package.
