How to read AUTOIN EP(EP2fifobuf) data and send it through RS232?

[lee]

Hi, I got the same problem. "Why in manual mode the slave fifo interface flags don't change?" 

and I can not get the answer from this case. It has been a long time since this case created.

Hi,

Please share details on your application and firmware source if not confidential.

Hi, Mallika, thank you for your reply. My files are attached bellow. And file cy68013_slavefio_ctr.v is the FIFO writing test of the FPGA side.

[lee]

In manual mode,  the slave FIFO flags don't change according with the FIFO writing event. Why?

In my FPGA code, the FPGA checks the FIFO's full flag, and if the full flag is not asserted, write data into the FIFO until it is full.

Hi,

What is happening with the data? Are you getting some data or not receiving it at all?

[lee]

I don't know whether the data have been receipt  by 68013 or not, cause the flags do not change with the FPGA write event.

Hi,

Apologies for the delay in my response.

Could you please attach waveforms for the FLAG signals? How are they changing?
