I just got my Nano 33 IoT and I am currently trying to set it up. I am getting an error saying the port is busy. I have spent around 8 hours now trying to figure this out, and I can't think of anything else.
I am able to put it into bootloader mode, which allows me to program the board, but when it starts regularly, I get the exact same thing. I have also tried uploading bare minimum sketches and still get the same issue.
I have the SAMD boards installed and the correct one selected. I also have the correct COM port selected. I have even tried uninstalling the boards/drivers and reinstalling them.
I have checked the device manager to make sure there are no discrepancies there either. The board uses a unique COM port and uses the correct driver.
I have also disabled Bluetooth, as I have seen that it may cause issues.
I have even checked Process Explorer extensively to see if any processes are actively using it. The only time that anything resembling the board pops up is when I open the Serial Monitor when in bootloader mode.
I have rebooted my machine multiple times with no luck. One thing that I do notice, though, is that right when I reboot it, I am able to open the Serial Monitor successfully. However, if I try to upload a new sketch or reset the board, it goes back into saying the port is busy.
I cannot think of anything else, so a little bit of help would be greatly appreciated.
