Cannot upload using Black Magic

[azlekov]

Hello, I'm able to build and upload zephyr based platformio project via BlackMagic. I was trying your stack for BLE developing. Everything seems to work as configuration and build but when I try to upload I got:

Configuring upload protocol...
AVAILABLE: adafruit-nrfutil, blackmagic, cmsis-dap, jlink, nrfjprog, stlink
CURRENT: upload_protocol = blackmagic
Looking for BlackMagic port...

The board is Adafruit Feather nrf52480 Express

Any ideas?
