无法在 GNAT 2019 社区版的 microbit 上运行 Ada 滚动文本演示

Question

我正在尝试运行此处描述的演示：https://blog.adacore.com/ada-on-the-microbit

我仔细按照教程的说明进行操作。我确实安装了 2019 版软件而不是 2018 版。 GPS 似乎已安装并在我的 windows 7 机器上工作。该项目已构建，但 pyocd-flashtool 似乎无法识别我的 microbit。它将其报告为 "generic cortex_m" 并抛出异常。

这是输出：

gprbuild --target=arm-eabi -d -PC:\Domains\ada\microbit_scrolling_text_demo\microbit_example.gpr
C:\Domains\ada\microbit_scrolling_text_demo\src\main.adb -largs -Wl,-Map=map.txt
Compile
   [Ada]          main.adb
Bind
   [gprbind]      main.bexch
   [Ada]          main.ali

   [link]         main.adb

有人知道哪里出了问题吗？

Answer 1

在 C:\GNAT19\lib\site-packages\pyOCD\board\mbed_board.py（或您平台上的等效位置）中，添加此行即可。

"9901": BoardInfo( "Microbit", "nrf51", "l1_microbit.bin", ),
