Some flags are not parsed from the boards.txt for SAMD

[JDuchniewicz]

I am trying to run Arduino Nano 33 IoT with this makefile and some variables are empty (mostly these related to PARSE_BOARD macro call).

I am sure that BOARDS_TXT does exist and that the macro is formed properly. I am not proficient enough in Makefiles to debug on my own where the issue originates from.

The exemplary logs are pasted below:

For now I am hardcoding all of them, but this does not construe an extensible makefile 😄

Update:
Despite hardcoding most of the paths, the definitions in samd board files cannot be found...

Okay, the issue was with supplying only nano instead of nano_33_iot because that is how the Bare-Arduino-Makefile instructed. So it looked like this:

BOARD_TAG = nano
BOARD_SUB = nano_33_iot

instead of

BOARD_TAG = nano_33_iot

[tuna-f1sh]

Just for reference in case you come across this again, nano in that project will be referring to the original AVR Arduino Nano https://www.arduino.cc/en/pmwiki.php?n=Main/ArduinoBoardNano

The Nano IoT 33 is a much newer board so you can assume any documentation with nano is the AVR board.

Thanks! I uploaded the PR to the other repo with clarification for the SAM boards.
