Thank you , Jesper SKov.
I have got the means of "exh 4".it means a exception happened,and the
exception number is 4.But I don't which exception it is.I maybe find it in
program.It's better if anybody give me some advice.
About microwin,I have turn on the arm7500's cache and write buffer.If I turn
off them, the operation of window will be slower,expecially in refreshing
window.
