I can build the filesystem image but I can not upload it. I get a permission error:
File “C:\Users\tmo.SHADOW-2018\.platformio\penv\lib\site-packages\serial\serialwin32.py”, line 64, in open
raise SerialException(“could not open port {!r}: {!r}”.format(self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port ‘COM4’: PermissionError(13, ‘Access is denied.’, None, 5)
*** [uploadfs] Error 1
 
any help would really be appreciated.

Hi.
Make sure you close all serial connections with the board.
Close all terminal windows (in VS Code) and Arduino IDE serial monitor window (if opened).
Then, try to upload the filesystem image again.
Regards,
Sara
