I used i.MX6Q and interfaced FTDI FT2232H in MPSSE mode on custom board, running it at 30MHz clock rate and Latency Timer is 255,
My FTDI FT2232H chip talk with ALTERA FPGA using SPI protocol.
I have downloaded libraries from below link and compiled with my App. code:
I observe that the output signals show Read and Write transactions taking almost 3ms instead of few micro seconds.
On the code side the Read transactions take maximum 500us.
So, Is there any setting inside FTDI chip to decrease these timing delays or Do I need to choose another drivers ?
