How to upload a new firmware on tk206 device

Abhinav5 years ago

Hi

I have tk206 device. I have tested this device and it works fine. I wanted to make some changes to the firmware running on the device. When I opened the device, I found no microcontroller inside it. I wonder how this is all working without a microcontroller/microprocessor.?

How can I make changes to the firmware which is already running on the device. I have found that a software named "multiport download tool" is used but not sure what type of file it accepts. Which programming language it uses. Can anyone please help. Thanks
