I need your help because I tried to unbrick my wireless router TP-Link WR940N V4 but something went wrong and now it restarts alltime. The only way is to connect to the board serial port.
Then, I have connected my TTL adaptor to the 3 pinholes installed on the board for Serial connection and made solder a couple of wire. Unfortunately my welds are badly made and I don’t have messages or texts displayed on my serial monitor (Putty).
As it is no more possible to make new solder (no more contact) , do you know if it is possible to find / connect Rx and Tx somewhere else that on “serial” pinholes ?
Perhaps it is possible to connect directly to serial Flash memory (25G32) or somewhere else ?
Thanks in advance for your help.
