How to Update Xiegu G90 Firmware? | 2022 Latest Guidance



This is the latest Xiegu G90 firmware update guidance for you all. With every new firmware releasing, more and more new features are available.

The following items are needed:
A. USB-to-Serial cable
B. G90
C. A computer running the Windows (XP/Vista/7/8/10/11) operating system
D. A 12-15V DC power supply (capable of supplying not less than 5A)
 

1. Install USB-to-Serial cable:
The very first thing is to make sure that the USB-to-Serial cable is working properly with the personal computer. The first time the cable is plugged into a USB port on the computer, the operating system will search for a driver file for this new hardware and automatically install the driver program. If all has gone well, we will be able to see the virtual serial port in the device manager program. If the driver file can’t be automatically installed by the operating system we will need to install it manually (driver files are available from the Radioddity G90 support page).

(Note: very early Xiegu USB-to-Serial cables used the Prolific Chip, currently supplied cables use a chip from FTDI, the old cables tended to be black in colour, the newer ones blue.)

After this action the virtual serial port and its port number will be visible in Windows Device Manager.

 

2. Wiring everything up:

2.1 Connect power cable

2.2 For updating the firmware in the head unit:

2.3 For updating the firmware in the base unit:




3. Update firmware via TeraTerm terminal software
(supplied in firmware zip file from Radioddity):
In order to transfer the firmware to the device, we use a serial terminal software program with XModem support called TeraTerm.

However, we are finding that some of the more aggressive Web Protection/Virus/Malware applications may be stripping the update and firmware files from the downloaded archive, or when the archive is extracted. The following link will allow you to download a certified virus-free Tera Term application used for the G90 update process.
