Anybody knows how to solve this error?

[shikhar623]

I am using a custom board, which includes XILINX fpga(xc4vfx100).

i want to access the FLASH memory(s29jl064h), using XPS for reading/writing data of the look up table during the execution of that code in Power PC.

I have  created new IP core, which will access the flash, when i make a new hardware in HARDWARE>>CREATE or IMPORT PERIPHERAL.

after creating the IP I did the following:

edited pcores \my_flash_v1_00_a\data\my_flash_v2_1_0.mpd file
and added flash ports

edited \pcores\my_flash_v1_00_a\hdl\vhdl\my_flash.vhd
and added user ports and port mapping statement

edited \pcores\my_flash_v1_00_a\hdl\vhdl\user_logic.vhd
 and added flash port defnition in 'user ports' area,'user signal declarations' and 'user logic implementation'.

I have IMPORTED the ipcore using the same wizard and also added it to the project.

still I am not able to BUILD the project: It show these ERRORS.:-

[rickysu · Accepted solution]

Your error relates to the pins of xps_gpio_0_GPIO_d_out_pin, not the Flash Memory Custom IP.

You assigned a pin location in UCF but it seems this pin is trimmed in the netlist.

You can take a look at your synthesized GPIO core netlist(ngc) or the report files (srp) in synthesis directory to find the clue of why it's trimmed.

If this pin is not used in your design, remove the UCF pin location assignment.

Ya , u were right.  .. i got the error corrected.. forgot to add fpga_0_ before gpio in .UCF.

How did u come to know?
