Duet 2 Wifi - Cannot update my Wifi module firmware

[Wei Jian]

I want to upgrade my firmware from 3.4.4 to 3.5.2. I managed to upgrade the main firmware using M997 S0, however I can't seem to update the Wifi module firmware using M997 S1.

This is the error message in YAT when I input M997 S1:

@Wei-Jian It looks like the WiFi module has failed. When and where did you purchase that board?

[droftarts]

@Wei-Jian Please try connecting via USB, and updating the WiFi module firmware, by:

1. Download a fresh version of the firmware. File "Duet2and3Firmware-3.5.2.zip" from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.2. Extract the zip file once it has downloaded.
2. Put the SD card from the Duet in your computer and copy file "DuetWiFiServer.bin" from the extracted folder to the /firmware folder of the SD card. Replace the SD card in the Duet.
3. Connect to the Duet via USB(see https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-2-connect-your-duet-via-usb)
4. In the serial terminal, send M552 S-1 to turn off WiFi.
5. Wait a couple of seconds, then send M552 to check the status. It should say "WiFi module is disabled".
6. Put WIFi into idle mode by sending command M552 S0. The response should be "WiFi module is started".
7. Send M552 again, and the Duet should reply with "WiFi module is idle".
8. Send command M997 S1 to update the WiFi firmware
9. Wait for a minute for the firmware to flash.
10. Reset the board and check the WiFi is working

If it doesn't work, or the responses are not the same as above, please post the full log from the serial terminal, showing what commands you sent, and what responses the Duet is returning.

@droftarts I tried all the steps you advised but seems like my Wifi module is not able to start up. I have attached the log from the serial terminal below.

The LED for my Wifi module did not light up throughout the whole process. Does it mean that it is faulty?

@chrishamm I purchased it directly from Duet3D about a year ago. It was working perfectly fine before I tried upgrading the firmware.

Thanks @droftarts and @Phaedrux for helping me resolve the issue with my board. I was able to get a warranty exchange for my faulty board. I reconnected to the new board and it is working fine now.
