Now I use the FPGA send short packet to FX3, but when data is sent completed,this FLAG is not updated.why?
Which flag are you talking about?
Can you please expalin your test procedure? Is it as follows?
1)FPGA and FX3 are programmed.
2)FX3 buffers are empty initially and you are sending a short packet from FPGA to FX3?
Please explain the test procedure. Also can you please provide the GPIF timing diagram?
