So I have a RM520N-GL that does not an AT, DM, or COM port communicating. I was able to get the module into EDL mode so QDownloader was available. I successfully flashed several different stock firmwares for this particular module, each says PASS, but when I restart the module I do not get an AT, DM, or COM port available. Is there any other way to reset a module to reverse whatever has been done to this device?
Please try to install the driver, I have sent it to you
Not sure if this specifically helped, but I did install it, reflashed really old firmware, then flashed into new firmware, and was able to run some AT commands. Thought I had everything set up in ECM mode, but I don’t have a connection with the internet through the ethernet port. eth_driver is r8125, usbnet is 1
The RM520-GL is up and running.
