I just got my MAX32 and I am having some trouble getting it to communicate with either one of my computers. I am running the latest version of MPIDE.
After I plugged it in for the first time, windows recognized something was plugged in and automatically installed the drivers. A USB serial converter appears in the device manager. The red LED is on and the green LED is blinking.
I opened MPIDE, selected MAX32 and COM1. I loaded the blink sketch and tried to upload it. It didnt work so I tried COM3. It didnt work either. I get communication and connection errors with COM3 that indicate it cant get a connection status.
What am I missing? I went through all the documentation I can find and I cant find an answer. Both of my computers do the same thing, I have tried changing the drivers to the ones in the drivers folder as well as changing the USB cable to no avail. Any suggestions would be greatly appreciated.

Find which com port is being used by the board by checking the list in Control Panel -> Device Manager (classic, not sure about new fangled Windows CP layout).

I tried looking under the com&lpt port but nothing ever shows up. The only indication I get that windows recognizes the board is under USB. It shows USB serial device, which disappears/reappears as I unplug/plug it in.

I'd uninstall whatever Windows installed by default (it often gets it wrong in my experience), then go to the FTDI site ( http://www.ftdichip.com/Drivers/VCP.htm ) and download the latest official Windows usb-serial drivers. Install those drivers before plugging in the board again.
