Followed build process for OpenSK, encounterd error

[Prosthet1cHead]

Following the instructions here: https://wiki.makerdiary.com/nrf52840-mdk-usb-dongle/opensk/building/

Everything appears to go well until the "board=nrf52840_mdk_usb_dongle ./deploy.sh app" stage, which dies as shown below.

I have zero rust language experience so can't debug this myself. Running the process as root on Ubuntu Mate 20.04.

I have the same issue

@xiongyihui could you please take a look? In the OpenSK upstream they fixed it with nightly-2020-02-03.

[xiongyihui]

The document is find of outdated. We can follow https://github.com/google/OpenSK/blob/master/docs/install.md to build the firmware.

./setup.sh
./deploy.py --board=nrf52840_mdk_dfu --opensk --programmer=none

It will create a hex at the target directory.

[xiongyihui]

Please use https://github.com/makerdiary/OpenSK/tree/master which includes a commit to avoid breaking the bootloader.

@xiongyihui I've downloaded the deploy.py script from google/OpenSK and run the following command:

./setup.sh
./deploy.py --board=nrf52840_mdk_dfu --opensk --programmer=none

But I got this error:

deploy.py: error: argument --board: invalid choice: 'nrf52840_mdk_dfu' (choose from )
