Overview

This chapter introduces the background information and application range of using standard Raspberry Pi OS on the ED-HMI2120 series.

Background
Application Range

Background

ED-HMI2120 series products have an operating system with BSP installed by default when leaving the factory. It has added support for BSP, created users, enabled SSH and supports BSP online upgrade. It is safe and reliable, and users can use the operating system.

NOTE

If the user has no special needs, it is recommended to use the default operating system. The download paths are ED-HMI2120-070C/raspios and ED-HMI2120-101C/raspios.

If the user wants to use the standard Raspberry Pi OS after receiving the product, some functions will be unavailable (For example, LCD screen is not available) after changing the operating system to the standard Raspberry Pi OS. In order to solve this problem, ED-HMI2120 supports online installation for Firmware packages to make the product better compatible with the standard Raspberry Pi OS and ensure that all functions can be used.
ED-HMI2120 supports the standard Raspberry Pi OS by installing a firmware package online on the standard Raspberry Pi OS (bookworm and Bullseye). The operations for the bookworm system and the bullseye system are different. Since the bookworm system is newer, so it is recommended to install a firmware package on the Bullseye system to support this application.

Application Range
The products involved in this application include ED-HMI2120-070C and ED-HMI2120-101C.
Since using a 64-bit operating system can better utilize the hardware performance of the product, it is recommended to use the 64-bit standard Raspberry Pi OS (bookworm and Bullseye). The details are as follows:

Product Model	Supported OS
ED-HMI2120-070C	Raspberry Pi OS(Desktop) 64-bit-bookworm (Debian 12) Raspberry Pi OS(Desktop) 64-bit-bullseye (Debian 11) Raspberry Pi OS(Lite) 64-bit-bookworm (Debian 12) Raspberry Pi OS(Lite) 64-bit-bullseye (Debian 11)
ED-HMI2120-101C

Installing Firmware Package
This section introduces the specific operations of installing the firmware package on the standard Raspberry Pi OS. It is compatible with the standard Raspberry Pi OS (bookworm, Debian 12) and the standard Raspberry Pi OS (bullseye, Debian 11).

Debian 11 (bullseye)
After flashing to eMMC of the Raspberry Pi OS (bullseye) on the ED-IPC2100 series, you can configure the system by adding the edatec apt source, installing the kernel package, and installing the firmware package, so that the system can be used normally.

Preparation
The flashing to eMMC and startup configuration of the Raspberry Pi standard OS (bullseye) have been completed.

Steps

After the device starts normally, execute the following commands in the command pane to add the edited apt source.
- https://apt.edatec.cn/pubkey.gpg. https://apt.edatec.cn/raspbian
Execute the following command to install the kernel package.

Execute the following command to install the firmware package.
ED-HMI2120-070C
ED-HMI2120-101C
TIP:
If you have installed the wrong firmware package, you can execute package” to delete it, where “package” is the package name.
After the installation is completed, execute the following command to check whether the firmware package is installed successfully.
ED-HMI2120-070C
The result in the picture below indicates that the firmware package has been installed successfully.
ED-HMI2120-101C
The result in the picture below indicates that the firmware package has been installed successfully.
Execute the following command to restart the device.

(Optional) Disconnect the connection between the display and ED-HMI2120, and power off ED-HMI2120. Then power on ED-HMI2120 again and restart it.

TIP:
This step is only required for Lite version systems. Since the Lite version of the operating system does not support a multi-screen display, when the display that is connected to the HDMI port on the ED-HMI2120 is not disconnected, after rebooting the device, only the connected display is available and the LCD screen is not available. So you need to disconnect the connection between the display and ED-HMI2120 first, and Power off ED-HMI2120. Then power on ED-HMI2120 again and restart it.

Debian 12 (bookworm)
After flashing to eMMC of the Raspberry Pi OS (bookworm) on the ED-HMI2120 series, you can configure the system by adding the edatec apt source, installing the kernel package, installing the firmware package, and disabling raspberry kernel upgrade, so that the system can be used normally.

Preparation:
The flashing to eMMC and startup configuration of the Raspberry Pi standard OS (bookworm) have been completed.

Steps

After the device starts normally, execute the following commands in the command pane to add the edited apt source.
https://apt.edatec.cn/pubkey.gpg.
https://apt.edatec.cn/raspbian.

Execute the following command to install and update the kernel package.
https://apt.edatec.cn/downloads/202403/kernel-change.sh.
Execute the following command to install the firmware package.
ED-HMI2120-070C
