Hello!
I used the slave fifo mode to transfer data from 68013A to cpld, and used the BeginDataXfer function. While I fill the buffer with {22 2A 0B 01 01 ... 01}(total 1024bytes and EP2 is 512bytes double buffer), the fd[15:0] bus will be come {22 2A 22 2A 22 2A ... 22 2A 01 01 01 01 ... 01}(512 words 22 2A and 512 words 01 01)? Why is it, does the BeginDataXfer function can only transfer the first word and copy it 512 times inside? Has any know it?
