I want to porting a project from Arty (Artix-7 xc7a35tcsg324-1 ) to the Nexys4-ddr (xc7a100tcsg324-1).
The design use the QSPI NOR flash as the storage, so it assigns the SCK to the L16 in Arty board.
My question is, when I use Nexys4-ddr and assign the SCK to pin E9, but E9 is a dedicated configuration pin.
Although I wrote the rules in xdc, I got such message as following:
[Common 17-69] Command failed: 'E9' is not a valid site or package pin name. ["C:/lab/test/test.srcs/constrs_1/new/demo.xdc":5]
How could I use the E9 pin in my FPGA design to control the NOR flash?
