hi all!
My question is how can i send and recieve data through the CPU that in the board to the FPGA,when i use the Tera Term (for example) and i write the data on my PC. because i can program only the FPGA by IMPACT but i can't send data to the FPGA.
I have enother question when i write C code and running it on the CPU that in the board how can i send data to the pmod? I mean is there eny comand that can do that?
thanks
As suggested above, an AXI interface is probably the best approach. You can add an AXI interface to your custom IP. Take a look at the Avnet Zynq Hardware Speedway tutorial for an example of how to create an AXI based custom IP:

-7000 All Programmable SoC Hardware (Vivado 2013.3 and 2014.4.1)
or take a look at Jeff Johnson's tutorial:

or Adam Taylor's 7 part series on creating a PL peripheral starting here:
