Platformio + pyUPDI Upload Probleme

Hallo zusammen,

Ich habe mir eine Umgebung über Platformio erstellt um die AVRmega0 
Serie zu programmieren. Diese verwenden UPDI als 
Programmierschnittstelle. Ich verwende pyUPDI als Uploader. Leider habe 
ich ein paar Probleme, wenn ich den "UPLOAD" Button in Platformio 
benutze:

*** [upload] Error 1
======================================================================== 
==================  [FAILED] Took 2.24 seconds 
======================================================================== 
==================The  terminal process 
"C:\Users\gigauser\.platformio\penv\Scripts\platformio.exe 'run', 
'--target', 'upload', '--environment', 'ATmega808'" terminated with exit 
code: 1.

Rufe ich pyUPDI im Terminal auf, funktioniert alles wie gewollt:

pyupdi -d mega808 -c COM3 -b 115200 -f .pio/build/ATmega808/firmware.hex
Device info: {'family': 'megaAVR', 'nvm': 'P:0', 'ocd': 'D:1', 'osc': 
'3', 'device_id': '1E9326', 'device_rev': '0.0'}
Programming successful

Meine platformio.ini sieht wie folgt aus:

[env:ATmega808]
platform = atmelmegaavr
board = ATmega808
framework =
upload_speed = 115200
upload_flags =
    -d
    mega808
    -c
    $UPLOAD_PORT
    -b
    $UPLOAD_SPEED
upload_command = pyupdi $UPLOAD_FLAGS -f $SOURCE

Ich bin mir sicher das ist nur ein kleines Problem, ich habe aber leider 
keine Ahnung von Python oder tiefgehender Konfiguration in Platformio.
Bin für jede Hilfe dankbar!
