A Master burst module want to write something via the
PLD-to-STRIP bridge. 14 beat a burst.
first the slavehready signal is ready. since begin the
translation, the slavehready signal goes down, and will
ever being ready untill reboot the system.
os is linux-2.4.19.

WHY?
 
Now I find that if the DMA's dest address is the SDRAM,
It will same as above. But if is the Single port ram(SRAM),
this DMA moudle worked as expected.
