Firmware upgrade


This article introduces how to burn the firmware file on the host computer to the flash memory of the LQ399PRO development board through a double male USB data cable. When upgrading, you need to select an appropriate upgrade method according to the host operating system and firmware type.

LQ399PRO Development Board

Host


Good double male USB data cable


Firmware file


There are generally two types of firmware files:


Single unified firmware


The unified firmware is a single file that is packaged and merged by all files such as partition table, bootloader, uboot, kernel, and system. The firmware officially released by Firefly adopts the 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 mirroring


That is, files with independent functions, such as partition table, bootloader, kernel, etc., are generated during the development phase. Independent partition mirroring can only update the specified partition, while keeping other partition data from being damaged, which is very convenient for debugging during the development process.

With the unified firmware unpacking/packaging tool, the unified firmware can be unpacked into multiple partition images, or multiple partition images can be merged into one unified firmware.

Windows

Tool: Androidtool_xxx (version number)


Note: The version of the tool used by different firmware may be different, please download the corresponding version according to the 'Notes on Using USB Cable to Write (Important)'


Install RK USB driver


Download Release_DriverAssistant.zip, unzip, and then run DriverInstall.exe inside. In order to use the updated driver for all devices, please select the driver uninstall first, and then select the driver installation.

Connect the device


The method for the device to enter the upgrade mode is as follows:


Disconnect the power adapter first:


One end of the double male USB data cable is connected to the host computer, and the other end is connected to the development board


Press and hold the RECOVERY button on the device and hold


Connect to power


After about two seconds, release the RECOVERY button


The host should be prompted to find new hardware and configure the driver. Open the device manager, you will see the new device Rockusb Device appears, as shown in the figure below. If not, you need to go back to the previous step to reinstall the driver.

Burn firmware


Download AndroidTool (if the system is Android8.1, version 2.54 or higher is required), unzip it, and run AndroidTool.exe in the AndroidTool_Release_v2.38 directory (note that if it is Windows 7/8, you need to press the right mouse button and choose to run as administrator) ,As shown below:

Burn unified firmware update.img


The steps to flash the unified firmware update.img are as follows:


Switch to the upgrade firmware page.


Press the firmware button to open the firmware file to be upgraded. The upgrade tool will display detailed firmware information.


Press the upgrade button to start the upgrade.


If the upgrade fails, you can try to erase the Flash by pressing the Erase Flash button first, and then upgrade. Be sure to erase and program according to 'Notes for Programming with USB Cable (Important)'


Note: If the laoder version of the firmware you burned is inconsistent with that of the original machine, please erase the Flash before upgrading the firmware.

Burn partition image


The partition of each firmware may be different, please pay attention to the following two points:


Use Androidtool_2.38 to flash ubuntu(MBR) and Android7.1 firmware using the default configuration;


Use Androidtool_2.58 to burn ubuntu(GPT) with the default configuration. To burn Android8.1 firmware, please perform the following operations first: Switch to the download mirror page; right-click on the table and select import configuration; select rk3399-Android81.cfg


Use Androidtool_2.71 to burn Android10 or Android9 firmware using the default configuration;


The steps to flash the partition image are as follows:


Switch to the download mirror page.


Tick the partition to be burned, you can choose more than one.


Make sure that the path of the image file is correct. If necessary, click the blank table cell to the right of the path to select again.


Click the execute button to start the upgrade, and the device will automatically restart after the upgrade is complete.

Linux


There is no need to install the device driver under Linux, just refer to the Windows chapter to connect the device.


Tool: Linux_Upgrade_Tool


Note: The tool version used by different firmware may be different, please download the corresponding version according to [Burning Instructions]


upgrade_tool


Download Linux_Upgrade_Tool (Linux_Upgrde_Tool_for_android8.1 is required if the system is Android8.1), and install it to the system according to the following method for easy calling:


unzip Linux_Upgrade_Tool_xxxx.zipcd Linux_UpgradeTool_xxxxsudo mv upgrade_tool /usr/local/binsudo chown root:root /usr/local/bin/upgrade_toolsudo chmod a+x /usr/local/bin/upgrade_tool

Burn the unified firmware update.img:

sudo upgrade_tool uf update.img

If the upgrade fails, you can try to erase and then upgrade. Be sure to erase and program according to the table of 'Notes for Programming with USB Cable (Important)'

# Erase flash Use the ef parameter to specify the loader file or the corresponding update.img sudo upgrade_tool ef update.img #update.img: the Ubuntu firmware you need to burn# Re-burn sudo upgrade_tool uf update.img

Flash partition image


Android7.1 and Android8.1 use the following methods:


sudo upgrade_tool di -b boot.imgsudo upgrade_tool di -k kernel.imgsudo upgrade_tool di -s system.imgsudo upgrade_tool di -r recovery.imgsudo upgrade_tool di -m misc.imgsudo upgrade_tool di -re resource.imgsudo upgrade_tool di -p paramater  sudo upgrade_tool ul bootloader.bin

Android9.0、Android10.0 Use the following way:

sudo upgrade_tool di -b boot.imgsudo upgrade_tool di -dtbo dtbo.img  sudo upgrade_tool di -misc misc.imgsudo upgrade_tool di -parameter parameter.txtsudo upgrade_tool di -r recovery.imgsudo upgrade_tool di -super super.imgsudo upgrade_tool di -trust trust.imgsudo upgrade_tool di -uboot uboot.imgsudo upgrade_tool di -vbmeta vbmeta.img

Ubuntu(GPT) Use the following way:

sudo upgrade_tool ul $LOADER
sudo upgrade_tool di -p $PARAMETER
sudo upgrade_tool di -uboot $UBOOT
sudo upgrade_tool di -trust $TRUST
sudo upgrade_tool di -boot $BOOT
sudo upgrade_tool di -recovery $RECOVERY
sudo upgrade_tool di -misc $MISC
sudo upgrade_tool di -oem $OEM
sudo upgrade_tool di -userdata $USERDATA
sudo upgrade_tool di -rootfs $ROOTFS

If an error occurs during the upgrade due to flash problems, you can try low-level formatting and erasing nand flash:

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