Hello, if you want to reprogram/upgrade the firmware (or program your callsign to the firmware), you need to follow these steps :
①Download the firmware https://dl2man.de/3b-trusdx-firmware.
②Enter the serial number (the serial number on the anti-static bag) and download the firmware.
③ Install the USB Driver for the CH340 driver and AVR-Dudess software (if the computer prompts that the AVR-Dudess cannot be installed), please use another computer to install it.
④Restart the computer and use USB cable to connect the mainboard (the computer will make a ding-dong sound at this time, indicating that the CH340 driver software has been installed successfully. If not, it may be that the USB cable has no data transmission function, try to use another USB data cable).
⑤ Open the AVR-Dudess software, and then program the firmware. Please follow the position circled in the picture below, set up the software, and then program.Opening Device Manager under Windows will show the assigned COM-Port(first image below)
