310719存疑点&error&warning

ERROR&WARNING

1.an initializer is not allowed on a local declaration of an extern variable

  旧程序:extern float ret=0;

  新程序:extern float ret;

      ret=0;

  外部变量的局部声明中不允许使用初始值设定项。更改后error解除。

2. no ULINK Device found

3.cannot load flash programming algorithm!

4.flash download failed-"cortex-m3"

5.JTAG Communication failure.

6.flash download failed-target DLL has been cancelled.

  3和4是成对的,5和6是成对的。这五个错误都是因为我的跳线断了,在我发现这个故障之后也没在细究报错原因。
