Problm, upload an Arduino Sketch

I am a new user in Github and have already published my problems in the Github forum under Visual Studio Code. I discovered that this is the wrong forum for my problem. I also didn’t know that “Forum PlatformIO and Forum Githup” are the same things.
sorry, if i broke the Forum rules.

I use Visual Studio 1.51.1. at OS: Windows_NT x64 10.0.19042.
I want to do a sketch (blink) to get to know the program.
When I load the sketch onto the board, I get an error message:

No device found on COM3
*** [upload] Error 1

The board is not connected to com3, but to com6. It seems that the port will change from com6 to com3 during the upload.

There seem to be two ports, port COM3 bootloader and COM6 MKR1000.

I would be grateful for an explanation of the phenomenon.

Have you tried to manually specify the upload port by adding upload_port = COM6 in the platformio.ini?

Hello MaxGerhardt
Many thanks for your response.
Yes i did that. Multiple times. Port 3 was set again and again.
I could not set port 6 manually after setting port 3 in PlatformIo.ini.
To select port 6, I had to repeatedly upload a sketch via the Arduino IDE. Then Port6 was also displayed in PlatformIo.
Regards Jurgen

I saw you sent me a message on another post on the same subject.
I replied to this message.

your Post

"No the Platform value is the microcontroller platform, and “Atmel SAM” is correct since the MKR1000 contains a Atmel SAMW25H18 System on Chip which in turn has the SAMD21 core MCU.

Does it help if you manually boot the chip into bootloader mode by quickly double-pressing the reset button and then press upload?"

regards Jurgen
