Running `make` does _not_ give a list of boards, as it should according to documentation.

INFO_UF2.TXT

N/A, it is about building.

What happened ?

When I want to build according to the instructions in the README.md:

git clone --recurse-submodules https://github.com/adafruit/Adafruit_nRF52_Bootloader
cd Adafruit_nRF52_Bootloader
make

the make should output a list of supported boards as the README.md documents:

Build using make

[…]

For the list of supported boards, run make without BOARD= :

make
You must provide a BOARD parameter with 'BOARD='
Supported boards are: feather_nrf52840_express feather_nrf52840_express pca10056
Makefile:90: *** BOARD not defined.  Stop

But I do not get a list of boards.

When I run make, I only get

Makefile:144: *** Sub Variant  is unknown.  Stop.

Regards!

How to reproduce ?

As written above:

1. git clone --recurse-submodules https://github.com/adafruit/Adafruit_nRF52_Bootloader
2. cd Adafruit_nRF52_Bootloader
3. make
4. Observe that no list of boards is given.
