Visual Studio crash

Hi 
I am still trying this environment with the board MKRWiFi1010 with a PC - Windows10 Pro.
I have an example from Arduino IDE, EthernetHTTPS.
Now I try to upload with the USB port.
After compiling without errors the program is uploaded, without errors, through COM20.
At the end of the upload the serial monitor is open automatically on COM20, but, I don't know why, when this board is uploaded the COM port change to COM15.
If I press ENTER inside the window of the Serial Monitor of Visual Studio crash, all disappear from the screen.

If I disable the auto-open of Serial Monitor I can upload through COM20, then switch to COM15 and open the Serial Monitor, when I press ENTER inside this window ... crash again.

If, after upload, I open a different monitor, TaraTerm ... No problem, I can see messages from the board.

Thanks for the report.

Can you attach the full build, and upload output with the verbose options shown at the top of the page?

Can you also confirm which port works in TeraTerm?
(The port it switches to during the upload process is only for uploading functionality)

We will investigate the crash in this scenario, but the root cause is the port not being connected to the board when entering data into the Serial Monitor window.

Here is the file.
After saved this file I switch the COM, because COM20 is no more available, now is COM15.
I open the Serial Monitor.
I press ENTER inside the Serial Monitor and Visual Studio crash.

If I use TaraTerm I must open COM15, is the only COM available.

I notice that the board MKRWiFi1010, when the bootloader is running, I see on COM20, when start the sketch change in COM15.

Thanks for the detail, so COM15 is the Serial Port of the board, COM20 is the uploader port.

When you connect the serial monitor in Visual Studio, does the connect button ever turn to Green Text to show it has connected? (connections in other programs to the same port must be closed first)

Yes is green.

I have uploaded with Atmel-IDE disabled, through COM20, OK
The program on the board is waiting the connection:
Quote:
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(50);                       // wait for a second
    digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
    delay(50);
  }


I see the led fast flashing.
I change to COM15 and press Serial Monitor, it's open, Connect is green, he says "Opening port - Port open". 
See screenshot.
But the led is still fast flashing waiting for connection.
Now I press ENTER in the Serial Monitor -> CRASH All disappear.

Does enabling DTR/RTS help at all in this scenario?

Does the LED stop blinking as expected when opening the port from Arduino IDE or TeraTerm?

More simple environment:

- I have restarted the PC
- The board is loaded, if I reset the board the lad flash fast waiting connection.
- If I open TaraTerm on COM15 the software on the board proceed.
- Close Taraterm and start again.

- I reset the board, the led flash fast waiting connection.
- I open Visual Studio - Continue without code - Extensions - vMicro - View Port Monitor
- See screenshot
- The led flash fast waiting connection.
- If I press ENTER three or four times -> CRASH

Again.
- I reset the board, the led flash fast waiting connection.
- I open Visual Studio - Continue without code - Extensions - vMicro - View Port Monitor
- But this time I press RTS in the lower left corner
- !!!!!! The board is CONNECTED !!!!!!!

That's all, had I forgotten to press a button?

Glad it has worked with the Serial options set, these may be automatically enabled in TeraTerm.  All options are detailed on this page for information.

We will update when the issue with the crash when not connected is resolved.

I confess that I have not seen the page you indicate to me, but ... if you look well the picture in that page you can see that the button RTS isn't activate.  Tongue

It is not enabled in that screenshot as it is simply showing where each control listed in the table is.

Whether you need to enable these depends upon the board you are connecting to, and its serial interface from my understanding, for example using a USB TTL adapter these may not even be connected.

True, in fact in all these years it is the first time that I have to manage the RTS signal. I remember using it at times of RS232.

But now let's move on, I have to manage Atmel-ICE now. 

But let's talk about it in another thread, if there are any problems. 

For now, thanks for your help.

The crash when entering data to a closed port, is now resolved in the latest release (21.01.06.3), available at the top of the board below:
