AVR Upload in Windows using USB Programmer not working

[ciphermaster]

Hi,

trying to upload a code to an ATMEGA328P using an AVR ISP MK2 does not work. In the Help, there is a Document saying:

https://docs.platformio.org/en/latest/platforms/atmelavr.html

[env:myenv] platform = atmelavr framework = arduino upload_protocol = stk500v2 ; each flag in a new line upload_flags = -Pusb

But this is only working on Linux.

On Windows, the correct Protocoll is avrisp2. Example:

C:\Users\xyz\.platformio\packages\tool-avrdude> .\avrdude.exe -c avrisp2 -p m328p

avrdude.exe: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.02s

avrdude.exe: Device signature = 0x1e950f (probably m328p)

avrdude.exe: safemode: Fuses OK (E:FF, H:D1, L:62)

avrdude.exe done.  Thank you.

But whatever I try to specify it is always looking for an COM-Port (Upload-Port). It does not work without an COM-Port:

For some development platforms it can be a USB flash drive (i.e. /media/<user>/<device name>)

Do you use Program target instead of uploading?
