'Operation not permitted' when trying to flash to Microbit

[Chien Jing Wei]

Hi I have been attempting to flash the OpenHayStack Firmware onto a nRF51822 chip, and everything went well until the final step when I try to deploy the image.

Steps to reproduce the behaviour:

1. Reach the 'Deploy' stage for the Microbit firmware (https://github.com/seemoo-lab/openhaystack/tree/main/Firmware/Microbit_v1)
2. Write the command: "make install DEPLOY_PATH=/Volumes/MICROBIT" in the terminal and in the "./Microbit_v1" directory
3. Error message shows: "cp: /Volumes/MICROBIT: Operation not permitted"

Expected behaviour was for the flashing of the image onto the nRF chip to be successful, but it was not the case as seen below:

OpenHaystack version:
0.5.2

macOS version:
Big Sur version 11.7.6

Would greatly appreciate any help for my problem, thanks!

Oh yes this was the nRF chip I was attempting to deploy: https://de.aliexpress.com/item/32917064741.html?spm=a2g0s.9042311.0.0.27424c4d89bPFv&gatewayAdapt=glo2deu
Could it be that the firmware does not work for this type of BLE beacon?
