I can debug the "hello" example.but when 
I reach the "====>" line ,I can't continue,why? Thanks very 
much!

You mean the program crashes or that you can't step it in GDB? If the
latter, this is completely expected because you are switching context into
a different thread[1].

The HAL_THREAD_LOAD_CONTEXT macro never returns.

[1] Well, the startup context isn't a thread in the kernel sense, but
still...
