WP76XX always keep in download mode

Hi,

My WP76xx always keep in download mode and it cannot get the AT port.
How can I solve it ?

is it working before?
is it working after you download new FW to it?

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?

in mangoh red board, there are two usb connector, one is for USB connection, another one is for UART2 console

Hi @jyijyi ,

I don’t use mangOH red!!!

Is that possible to solve it by some command or using DM port ?
