出现如下错误：

Traceback (most recent call last):
  File "../zubax_chibios/tools/make_boot_descriptor.py", line 251, in <module>
    in_image.app_descriptor.version_major,
  File "../zubax_chibios/tools/make_boot_descriptor.py", line 225, in app_descriptor
    self._contents.seek(self.app_descriptor_offset)
TypeError: 'NoneType' object cannot be interpreted as an index

我使用的是5.4版本的交叉编译工具链，更新到6.3.1即可解决此问题

希望对你有帮助！
