I have a Portenta Machine Control board. I'm having issues programming it.
According to the documentation it should program just like a regular Arduino like an Uno. Hit the program button and let it rip.
What I get is different. After uploading the USB serial port is no longer recognized.
If I let it just sit there eventually the programming fails.
At this point the Portenta is out to lunch and will not respond until I push the reset button. From trial and error if I push the reset button as soon as the windows message appears the programming end successfully.
Am I doing something wrong?
This is the output I get.
