TMS320F280025C: F280025 controlcard 配置GPIO28为GPIO input时debug报错

Part Number: TMS320F280025C
Other Parts Discussed in Thread: C2000WARE

1.GPIO配置GPIO28为输入;

2.保存配置文件编译成功,再debug,报错;

3.退出debug后,开发板没有下电,再次进入debug,报错。

当我去除GPIO28的配置后,开发板重新上电可以正常debug。如果我是release烧进flash,后面板子无论如何都连接不上,仿真器test connection是一直fail。我最后发现我把外部晶振的拨码拨到使用内部晶振时才可以重新连接板子,烧回正常的程序,再拨回外部晶振才能恢复正常。

现在我开发需要用到GPIO28,如果设计才能在controcard上正常配置GPIO28,测试GPIO28的输入读取。
