A problem about using 68013A connect with ARM9 in full speed
We using external logic control 68013A in slave FIFO mode , It connect with ARM9 by linux only in full speed mode. Now we have a problem . when we using ARM wirte 68013A ,the speed can reach 200K , but when we read ,the speed only 25k,too slow.
Can you give some advice,what the problem? the firmware ,the dirver(this dirver of linux were make by ourself) or something we need setting up for linux kernel.
Thank very much
