Problem uploading firmware to M5Dial

Software / Firmware Jackpot Board / FluidNC
1

I am trying to make a pendant for my Jackpot controller, using Bart Dring’s design. I am trying to upload the firmware to the M5Dial, but I keep getting com port failures. I have tried several suggestions that I have found on the web, not specifically for the M5Dial, but this hasn’t worked so far.
The terminal log is:

 *  Executing task: C:\Users\alanp\.platformio\penv\Scripts\platformio.exe run --target upload --environment m5dial

I have tried changing com port from com 7 to com 2, with the same result.

Does anyone have any suggestions (apart from launching it through the window)?

First thing is to verify the correct com port. It should only appear when the dial is plugged in and disappear when it’s unplugged - is that happening?

3

Yes, the com port appears when the dial is plugged in. As I stated, I have tried changing the port to port 2, with no difference. I have also tried changing the baud rate of the port from the default 9600 to 115200 with no difference.
As you can see by the terminal log from the upload attempt, it finds the port, then can’t find it

You’re connecting via USB directly to a Windows computer, right? Do you get a notification from Windows that it’s detected a new USB connected device?

I don’t know if the following is applicable, but maybe it could help. I found it on a docs page at m5-docs

“When connecting the Type-C data cable to the computer, you must hold down the G0 button and insert the USB port. After connecting, the software will pop up Found New Device.”

The following illustration was shown:

That sorted it Doug.
Thanks! You’re a star :+1:
