Upgrade the firmware via USB cable

2.1. Introduction

This article describes how to upgrade the firmware file on the host to the flash memory of the development board through the Type-C data cable. When upgrading, you need to choose the appropriate upgrade mode according to the host operating system and firmware type.

2.2. Preparatory Tools

  • ITX-3588J development board
  • Firmware
  • host computer
  • Type-C data cable

There are two types of firmware files:

  • A single unified firmwareThe unified firmware is a single file packaged and merged by all files such as the partition table, bootloader, uboot, kernel, system and so on. The firmware officially released by Firefly adopts a unified firmware format. Upgrading the unified firmware will update the data and partition table of all partitions on the motherboard, and erase all data on the motherboard.
  • Multiple partition imagesThat is, files with independent functions, such as partition table, bootloader, and kernel, are generated during the development phase. The independent partition image can only update the specified partition, while keeping other partition data from being destroyed, it will be very convenient to debug during the development process.

Through the unified firmware unpacking / packing tool, the unified firmware can be unpacked into multiple partition images, or multiple partition images can be merged into a unified firmware.

2.3. Windows

2.3.1. Install RK USB drive

Download Release_DriverAssistant.zip, extract, and then run the DriverInstall.exe inside . In order for all devices to use the updated driver, first select Driver uninstall(驱动卸载) and then select Driver install(驱动安装).

2.3.2. Connected devices

we can put the device into upgrade mode by hardware as follows:

put the device into upgrade mode by software as follows:

Type-C data cable is connected, use the command in the serial debugging terminal or adb shell

reboot loader

The host should prompt for new hardware and configure the driver. Open Device manager and you will see the new Device Rockusb Device appear as shown below. If not, you need to go back to the previous step and reinstall the driver.

2.3.3. Upgrade the firmware

In order to avoid the burning problem caused by the Androidtool_xxx version, it is recommended to use the tool packaged inside the public firmware package for burning. After decompressing the public firmware package, it is as follows:

ITX-3588J_Android12_HDMI_220308 ├── ITX-3588J_Android12_HDMI_220308.img ├── linux │ └── Linux_Upgrade_Tool_v1.65.zip └── windows ├── DriverAssitant_v5.1.1.zip └── RKDevTool_Release_v2.84.zip

we could also download Androidtool_xxx (version number) individually . AndroidTool defaults to display in Chinese. We need to change it to English. Open config.ini with an text editor (like notepad). The starting lines are:

#Language Selection: Selected=1(Chinese); Selected=2(English) [Language] Kinds=2 Selected=1 LangPath=Language\

Change Selected=1 to Selected=2, and save. From now on, AndroidTool will display in English.Now, run AndroidTool.exe: (Note: If using Windows 7/8, you’ll need to right click it, select to run it as Administrator)

  2. Press the “firmware” button to open the firmware file to be upgraded. The upgrade tool displays detailed firmware information.
  3. Press the “upgrade” button to start the upgrade.
  4. If the upgrade fails, you can try to erase the Flash by pressing the EraseFlash button first, and then upgrade.

Note: if the firmware loadder you wrote is inconsistent with the original one, please execute EraseFlash before upgrading the firmware.

2.3.3.2. Upgrade Partition image

The steps to upgrade the partition image are as follows:

  1. Switch to the “download image” page.
  2. Check the partition to be burned, and select multiple.
  3. Make sure the path of the image file is correct. If necessary, click the blank table cell on the right side of the path to select it again.
  4. Click “Run” button to start the upgrade, and the device will restart automatically after the upgrade.

2.4. Linux

There is no need to install device driver under Linux. Please refer to the Windows section to connect the device.

2.4.1. Upgrade_tool

Download Linux_Upgrade_Tool, And install it into the system as follows for easy invocation:

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

2.4.2. Upgrade unified firmware - update.img：

sudo upgrade_tool uf update.img

If the upgrade fails, try erasing before upgrading.

erase flash : Using the ef parameter requires the loader file or the corresponding update.img to be specified. # update.img :The ubuntu firmware you need to upgrade. sudo upgrade_tool ef update.img # upgrade again sudo upgrade_tool uf update.img

pgrade Partition image

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 #upgrade parameter sudo upgrade_tool ul bootloader.bin #upgrade bootloader

If the upgrade fails due to flash problems, you can try low-level formatting and erase nand flash:

sudo upgrade_tool lf update.img # low-level formatting sudo upgrade_tool ef update.img # erase

2.4.3. fastboot

Download [Linux_adb_fastboot], And according to the following method to install into the system, easy to call：

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

fastboot Burn dynamic partitions

adb reboot fastboot # enter bootloader sudo fastboot flash vendor vendor.img sudo fastboot flash system system.img sudo fastboot reboot # After the burn is successful, restart

2.5. FAQs

2.5.1. 1. How to forcibly enter MaskRom mode

A1 : If the board does not enter Loader mode, you can try to force your way into MaskRom mode. See operation method “How to enter MaskRom mode”.

2.5.2. 2. Analysis of programming failure

If Download Boot Fail occurs during the programming process, or an error occurs during the programming process, as shown in the figure below, it is usually caused by the poor connection of the USB cable, the inferior cable, or the insufficient drive capability of the USB port of the computer. Troubleshoot the computer USB port.
