问题
I'm trying to run the demo described here: https://blog.adacore.com/ada-on-the-microbit
I followed the tutorial's directions carefully. I did install the 2019 versions of the software instead of the 2018 versions. GPS seems to be installed and working on my windows 7 machine. The project builds but pyocd-flashtool can't seem to recognize my microbit. It reports it as a "generic cortex_m" and throws an exception.
Here's the output:
gprbuild --target=arm-eabi -d -PC:\Domains\ada\microbit_scrolling_text_demo\microbit_example.gpr

Anyone know what could be wrong?
回答1:
In C:\GNAT\2019\lib\site-packages\pyOCD\board\mbed_board.py (or the equivalent location on your platform), add this line and it will work.
"9901": BoardInfo( "Microbit", "nrf51", "l1_microbit.bin", ),
