slaveFIFO write,data repeat received

I made a slavefifo project.Using FPGA write data into the FX3.But when I run the project sometime.The data received have some error.Some data repeat received.

The data FPGA wrote into the FX3 is auto add one once a time.For exampl,the data is 1,2,3,4,5.. and so on.

But sometimes PC received  data is 1,2,3,4,5,2,3,6,7.The data 2,3 is receive twice.But I just write into the FX3 once.

So,I want to know what operation result in this.The problem don't always exist.It just sometimes and when I run more than 5 or 6 minute.

Hi,

What is the width of data bus?

Are these repetitions occuring nearby (i.e. like your example after 2 bytes) or there is randomness?

Regards,

Anand
