Can't turn on Vim2, what to do?

The question was solved by itself, could update through the PC. Everything works under the new firmware


Do you have any USB<>TTL converter ( )?

If yes, try connect it, to Linux_TX, Linux_RX and GND

Then connect to /dev/ttyUSB0 (or COMx in Windows) using putty, and power on the board.

Paste here the startup log.

Describe in detail what you did.
