Upload firmware with platform.io fails. Upload with kflash_gui is working.

Platform.io version: Core 4.3.4, Home 3.2.3 Kendryte K210 platform version: 1.2.2

platform.ini

[env:sipeed-maix-go]
platform = kendryte210
board = sipeed-maix-go
framework = arduino

; serial monitor baudrate
monitor_speed = 115200

upload_port = /dev/ttyUSB1

Upload - Error:
