First build hello_world and with error could not open COM port
Posted: Tue Oct 23, 2018 3:23 am
I am just a new one to ESP32 , and going to working under windows 10 ，so I just do with the official recommend that with the IED eclipse and download the esp-idf form offical host page ，and commend make menuconfig was also added and it worked well,till now everything seems to be alright but , when I first build my project hello_world ,
there goes a error like this:
raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 2] could not open port /COM4: [Errno 2] No such file or directory: '/COM4'
and actually I finished the build , so I check the COM port , it does exist for when I open the SSCOM it worked well and even I can get some message print out that I have flashed in to this board under linux , so I just wonder where I go wrong ? I have searched this answer for 2 days and some said its the python's version that made this error , I have tried all the answer I searched form Internet , but can not resolve this error still , can anybody help me here..?
My English is not so good , but I'd try my best ..
