Thank you for your help.
I will ask you a question.
OS: Windows10 Pro 64bit
FX3 EZ USB
At USB Control Center,
After reading the img file in USB boot mode, the tree on the left side of the screen disappears and the work cannot be performed.
If it is a manual, it seems that you can work with DataTransfers etc. after reading the img file, but the tree disappears
You will not be able to work.
If you are aware of these phenomena and how to solve them, I would like to have a professor.
Please check if the device enumerated in the device manager (check under other devices and usb devices)
Also let me know which firmware did you program the fx3 with? Is it the default firmware from the SDK or custom one?
