Hi Cris,

Finally I know what's wrong with my program. :)

Actually it was caused by a misplacement 'waitrequest' signal in the avalon slave MM. So this misplaced 'waitrequest' signal caused the 'write' signal from CPU kept high and blocked other process. Now my system and its program can work correctly :)

Btw Cris, I have some questions about RS-485 (in a new thread), I'm really appreciate if you want to help me :)

Thanks :)
