Looking at the log more carefully I see that even FX3 is not programmed properly. So, we have to solve this issue first.
Could you check if “FX3 BOOT” jumper is mounted properly (next to USB connector), please. Try to unmount - mount it again to ensure there is a proper connection.
One more question - what about LED’s? Is there any activity?
After your message I tried to connect the board and it was working for a week and then broke down again as I describe in first post. Next day it’s begin working again and work until now. What can it be?
About your questions: the whole board look like others no changes. About leds - when I got WestBridge - two leds are red and two leds are green.
