Hi @jyijyi ,

  1. Yes.
  2. I can’t download FW. It no response when I download the FW.

do you see any debug message in UART2 console?

BTW, there is a boot pin called TP1 in pin 47 which can be used to force the module to enter boot-loader mode on power up for downloading FW via DM port

Hi @jyijyi ,

What does mean UART2 , /dev/ttyUSB2?

By the way I use windows and I only see DM port.

UART2 is the console, when module boot up, there will be some message coming out from the bootloader to this port

Hi @jyijyi ,

How can I connect to UART2, I use PCIE to USB to connect to my windows.
And I only saw DM port, so what is UART2 port name in windows?
