Flowcode Support Board

Hi. I'm following the example described in the Flowcode Getting started guide (blinking an led on and off with a 1 second delay) but I get this error message:
C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\AVR\batchfiles\avrc_arduinoB.bat reported error code 0x3
Any ideas? I'm new to this
Thanks

Hello.
Can you post your .fcfx project file?
To do that you will need to click Full Editor & Preview and then select the Attachments tabs.

I think this is it

I believe error code 3 is "programmer is not responding". Maybe check that the COM port for the Arduino is correct (in build settings).
