Downloading to Mixtile Edge 2

Edge 2 comes with Android 11 pre-installed, and it can be updated with any custom built firmware. The system firmware may be updated via either an USB cable or a MicroSD card and system local update. Under normal circumstances, the local update method is preferable for the users. Just like Android phones, they can choose the local update package to upgrade. Users with specific requirements who need to burn the system with USB cable and SD cards should back up their data in their own method.

The A/B (Seamless) system update is used by Edge 2. Edge 2 will not brick unless the hardware is damaged.

What you need

  1. A downloaded firmware
  2. Firmware update tool
  3. Edge 2 device
  4. RK-USB driver (only for updating via USB cable with Windows)
  5. MicroSD card/USB drive with more than 2GBytes capacity (only for updating via MicroSD card)

System Local Update

This method is very straightforward and simple to comprehend and it will not delete the user data. A good-quality SD card or USB disk is required. Ensure that there is no power interruption during the local update method.

(Note: This updating method is only available in Android system, not available in Debian system)

Step 1: Update preparation

Step 2: Update operation

  • When you choose the appropriate update package, the system will display a power connection confirmation screen.

  • Click Update to enter the update status page. The screenshot is as follows:
  • Wait a few minutes for the update to finish. The following dialog box will appear; click the REBOOT button to restart the system. The process of updating is now complete.

Update Methods of Full System Image

Two distinct methods for updating system firmware are demonstrated step by step. To upgrade your Edge 2 system with the latest firmware, follow the procedures below.

USB cable update

Connect the Edge 2 to a PC via USB Type-C cable; the firmware update tool takes around 1 minute to burn the firmware.

MicroSD card update

Use the upgrade card making tool to make the MicroSD card into an upgrade card. Then insert the upgrade card into the motherboard, turn it on, and the system will upgrade automatically in about 5 minutes.

Important: These update methods will delete all user data. Please back up the data before performing the update.

    There are two ways to enter the Loader mode:
  • Press and hold the RECOVERY button, then power on. Continue holding the RECOVERY button until the RKDevTool displays Loader mode, then release the RECOVERY button.
  • After the system is running, input adb reboot loader through the serial terminal or ADB terminal.
  1. Maskrom mode
    Maskrom mode can be used for updates when the bootloader or uboot is broken. To enter Maskrom mode:
  • Press and hold the MASKROM button, then power on. Continue holding the MASKROM button until the RKDevTool displays Maskrom mode, then release the MASKROM button

Updating Steps in Windows System

Updating Steps in Ubuntu System

Two upgrade tools can be used in Ubuntu, and both tools require a USB cable.

Step 1: Download upgrade tool

Step 2.1: Install upgrade tool

Edge 2 boots into Loader/Maskrom mode

  • Install Upgrade_Tool:
unzip Linux_Upgrade_Tool_xxxx.zip
cd Linux_UpgradeTool_xxxx
sudo mv upgrade_tool /usr/local/bin
sudo chown root:root /usr/local/bin/upgrade_tool
sudo chmod a+x /usr/local/bin/upgrade_tool
  • Upgrade firmware:
Unified firmware upgrade:
sudo upgrade_tool uf update.img

Mirrored partition upgrade:
sudo upgrade_tool di -b /path/to/boot.img
sudo upgrade_tool di -r /path/to/recovery.img
sudo upgrade_tool di -m /path/to/misc.img
sudo upgrade_tool di -u /path/to/uboot.img
sudo upgrade_tool di -dtbo /path/to/dtbo.img
sudo upgrade_tool di -p paramater
sudo upgrade_tool ul bootloader.bin

If the upgrade is abnormal or fails, you can low-level format, then upgrade.
sudo upgrade_tool lf update.img # low-level format
sudo upgrade_tool ef update.img # Erase

Step 2.2: Install Fastboot

  • Install Fastboot:
sudo mv adb /usr/local/bin
sudo chown root:root /usr/local/bin/adb
sudo chmod a+x /usr/local/bin/adb
sudo mv fastboot /usr/local/bin
sudo chown root:root /usr/local/bin/fastboot
sudo chmod a+x /usr/local/bin/fastboot
  • Upgrade firmware with Fastboot:
adb reboot fastboot
sudo fastboot flash vendor vendor.img
sudo fastboot flash system system.img
sudo fastboot reboot

Updating Full System Image with MicroSD card

Step 1: Preparation

Step 2: Download MicroSD card building tool

Note: As Edge 2 uses A/B (Seamless) system update, SD_Firmware_Tool requires additional configuration.

  • open config.ini under SD_Firmware_Tool file folder

Step 3: Build update MicroSD card

  • Open SD_Firmware_Tool.
  • Follow the instruction in the below figure

Step 4: Update system
