QHYCFW3 firmware update problem

[IDM]

Hi,

I just bought a QHY CFW3 and have tried to follow QHY's firmware update instructions but when I press upload I get the following message:

avrdude.exe: invalid file format '/cfw3' in update specifier

avrdude.exe: error parsing update operation 'flash:w:C:/cfw3'

 

Any ideas on what I am doing wrong?

Thanks,

Ian

No idea what went wrong with your update, I updated the firmware on my QHYCFW3M around 18 months ago and all went well.

Did you download the firmware update from the QHY product page below?

Hi, Yes I downloaded everything from QHY website. I have done some testing today and the wheel is definitely still bi-directional. I will have to contact QHY and se what they say 😕

Just an update as I now have the firmware upgrade sorted. I contacted QHY and raised a ticket and I have to say they couldn't have been more helpful. They asked questions and I answered, there responses always being within 24 hours. Ultimately they couldn't see what I was doing wrong so they asked me to download Anydesk onto my PC and give them permission to do the update for me remotely which they did and it worked. Excellent support.

It appears that for reasons I don't understand the Hex file needs to be on your desktop not in a folder. If it is in a folder, even it you navigate to it, the upload fails. Hope this information might help someone else trying to do the upgrade.

Cheers
