Upgrading firmware on Windows¶
Preface¶
This article describes how to burn the firmware file on the host computer to the flash memory of the Core-3568J development board through 双公头USB数据线. When upgrading, you need to choose an appropriate upgrade method according to the host operating system and firmware type.
Preparatory work¶
Core-3568J development board
Firmware
Host computer
Double male USB data cable
Firmware file¶
There are two types of firmware files:
A single unified firmware
The 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 images
That 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.
Flash on windows¶
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
and then select Driver install
.
Connected devices¶
You can put the device into upgrade mode as follows:
Disconnect the power adapter first:
Dual male usb data cable connects one end to the host and the other end to the development board.
Press the
RECOVERY
button on the device and hold.Connect to the power supply.
About two seconds later, release the
RECOVERY
button.
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.
Upgrade the firmware¶
Download Androidtool_xxx (version number). 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:
#选择工具语言:Selected=1(Chinese);Selected=2(English)
[Language]
Kinds=2

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. 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.
