Upgrade Firmware Using Rockchip Format Image

You can upgrade firmware of Mixtile Core 3588E (hereinafter referred to as Core 3588E) using either an RK image or a raw image in Loader or MaskROM mode. This document describes how to upgrade the firmware of Core 3588E using a Rockchip format image on macOS, and Ubuntu in Loader and MaskROM modes.

Important:

Back up data before a firmware upgrade, because all user data is deleted after the firmware upgrade.

Note:

Core 3588E has three boot modes: Normal, Loader, and MaskROM. Loader and MaskROM modes are for firmware upgrade.

Preparations

Files

Upgrade tools

Devices and accessories

  • A Core 3588E board
  • A carrier board that is compatible with Jetson TX2 NX (carrier board Leetop A206 is used in this document)
  • A computer: macOS, or Ubuntu
  • A micro USB cable
  • A 2.54-mm jumper cap

Connect hardware

1. Fix Core 3588E onto the carrier board with the notch aligned. Then fasten the two screws.

Figure 1. Installing Core 3588E onto the carrier board

2. Connect one end of the power adapter to the power jack of the carrier board and the other end to a live outlet.

3. Connect one end of the micro USB cable to the micro USB port of the carrier board and the other end to your computer.

On macOS

Step 1. Enable Core 3588E to enter Loader mode

Choose one of the following two options:

Option 1: Unplug the power adapter, use the jumper cap to connect the FCREC and GND pins, and plug the power adapter again.

Option 2: If your computer has ADB tool, start a terminal and input adb reboot loader.

Step 2. Download the upgrade tool and grant permission to it

2.1 Click upgrade_tool_v2.3_mac.zip to download the upgrade tool.

2.2 Go to the folder upgrade_tool_v2.3_mac after unzipping the package. Grant permission to the tool by running the sudo chmod u+x upgrade_tool command.

2.3 Navigate to System Preferences > Security & Privacy and allow this file to run on your computer.

Under the folder upgrade_tool_v2.3_mac, you can run the sudo ./upgrade_tool command to check whether Core 3588E has entered Loader mode. The following is an example of the command output:

Program Log will save in the /Users/mia/upgrade_tool/log/

DevNo=1	Vid=0x2207,Pid=0x350b,LocationID=442	Mode=Loader	SerialNo=4998310c6679ec2
Found 1 rockusb,Select input DevNo,Rescan press <R>,Quit press <Q>:

Step 3. Upgrade raw image

3.1 Under the folder upgrade_tool_v2.3_mac, run the sudo ./upgrade_tool uf [image path].img command. The following is an example:

sudo ./upgrade_tool uf /Downloads/image-release-rockchip-format-mixtile-core3588e-ubuntu-desktop-rc-0.0.3-231227.img

On Ubuntu

Step 1. Enable Core 3588E to enter Loader mode

Choose one of the following two options:

Option 1: Unplug the power adapter, connect the FCREC and GND pins using the jumper cap, and plug the power adapter again.

Option 2: If your computer has ADB tool, start a terminal and input adb reboot loader.

Step 2. Download the upgrade tool and grant permission to it

2.1 Click Linux_Upgrade_Tool_v1.65.zip to download the upgrade tool.

2.2 Go to the folder Linux_Upgrade_Tool_v1.65 after unzipping the package. Grant permission to the tool by running the chmod u+x upgrade_tool command.

Under the folder Linux_Upgrade_Tool_v1.65, you can run the sudo ./upgrade_tool command to check whether Core 3588E has entered Loader mode. The following is an example of the command output:

Upgrade firmware in MaskROM mode

On macOS

Step 1. Enable Core 3588E to enter MaskROM mode

1.1 Unplug the power adapter from the carrier board.

1.2 Keep short-circuiting the two solder joints on Core 3588E, and plug the power adapter again.
