Hi, did you select the correct board from the ‘boards’ option?

Hi Shaun,

Welcome to the forum! As a first step, have you run through the steps on this error on the Arduino site?

Could you shoot through a photo of how everything is connected? Could you share a screenshot of your IDE’s programming menu? i.e.

hi James
sorry for the late reply , FYI on a GIGA R1 its a DFU 74 error when you try an load the code , its all over the internet,
How i got round it , was compile the sketch first, Then do a double press of the reset then hit up load , this fixes it , if you power down, and try to do a reload you may need to repeat the process
