@dc42 ok, apologies, I thought the two problems may have been interconnected as the paneldue went on the blink immidiately after the firmware update...interconnected

@dc42 Well, I feel a bit daft now, changed baud rate to 5700 and all is well! If my Duet has incorrect baud rate set could that be the cause of my Firmware problem?

Yes, that is correct, tried on 2 Duet boards, updated firmware twice, checked resistance of each conductor on 4 way cable and tried 10 way ribbon cable..

Resistance all below 0.1 Ohm, I get the same problem with the 10 way ribbon cable as well...

I have uprated the firmware again and tried on Duet 2 WiFi and Duet Maestro to no avail. I even used a brand new good quality USB lead. I bought it on May 24th last year so out of warranty. Do you know if it is repairable?

@Phaedrux I have just connected the Paneldue to my Maestro board and get the same problem, when I look at the card contents, Paneldue says files on card 0, nothing works except foe settings....

@Helensdad said in Firmware update failure..:

after downloading the combined firmware.bin file, I tell it to update, it then drops the Wifi connection and reverts back to 1.0.3...

This part makes me think that the files might not be placed in the /sys folder or that there might be other files there or files not named correctly and so an older file is being used.

Can you provide a screenshot of the SD card directory structure?

@Phaedrux said in Firmware update failure..:

Normally I would suggest to replace the 4-wire cable with a new one, but you've already tried the ribbon cable option with the same result.

Which version of PanelDue is it? Which PanelDue firmware did you use to flash it? Perhaps there was a mismatch. It is a Paneldue 7i and I used 1.24 for 7i downloaded from your repository...

Here is the link to Ooznest firmware, I will trt the Duet firmware tomorrow, I have a job running now. All works ok from web interface, it even reads the card. It is just the Paneldue I have to sort now....

@Phaedrux Yes, I updated it this afternoon via USB...
