Can't get rid of "ID:169085 No exact pin location assignment(s) for 72 pins of 135 total pins.

Hello all,

As the title suggests. I can't get rid of the message:

"ID:169085 No exact pin location assignment(s) for 72 pins of 135 total pins. For the list of pins please refer to the I/O Assignment Warnings table in the fitter report."

A little background. I'm working on a Cyclone V HPS. I set the SDRAM parameters with the tcl scripts "hps_sdram_p0_pin_assignments" and "hps_sdram_p0_parameters". I'm setting my FPGA IO pins manually, and the HPS pins are set automatically.

The project compiles successfully, and I am able to boot a Linux system from an SD card and peripherals work ok.

When I look at the "Pin Planner" after compiling, my custom FPGA pins were assigned manually, and a new "Fitter" column has the location of the HPS pins.

I cannot change the values for "Location" on the Pin Planner, I get an error message.

How can I get rid of the "ID: 169085 No exact pin location assignment(s)..." message? What do I need to do to to correct the pin assigment? What am I missing? I looked at the help entry but I could not get more information, nor other examples.

Cheers,

Alberto
