(Arduino IDE 2.0.4) M0 listed in boards connected to COM9. Had successfully uploaded code mods 8-10 times. Now it will not load code and output says "No device found on com9" though the IDE status bar says the"...M0(SAMD21) on COM9".
I have reloaded IDE and sketch. dis/reconnect USB, powered the M0 on/off with switch and still it won't upload code.
What have I missed?
Thx, Tom

Re: Gemma M0 stopped loading code
The bootloader's USB firmware might be crashing.
Enable verbose messages during upload in the Arduino IDE's preferences, try to upload a sketch, and when you see the lines that begin with 'PORTS' start to scroll past, double-click the Gemma M0's reset button. That will force it to reboot and open a new USB connectiopn to the computer while the IDE is waiting for a new USB device to appear.
That usually gets things back in sync.
