i have some problem to store data in a flash located on Nexys 4.
Vivado tell me that is a s25fl128s, i have searched on the web and i found that STARTUPE2 USRCCLKO control post configuration access to spi.
I create a fsm that connect clk of my top level entity to this pin and i create a tri-state component to use inout port to connect to spi interface, i want to use flash in single spi mode.
I try to read from a register by writing a command, i see this command is correct in ila interface (in term of timing and information), but when i want to read data, i don't see anything.

Vivado tell me that is a s25fl128s, i have searched on the web and i found that STARTUPE2 USRCCLKO control post configuration access to spi.
I create a fsm that connect clk of my top level entity to this pin and i create a tri-state component to use inout port to connect to spi interface, i want to use flash in single spi mode.
I try to read from a register by writing a command, i see this command is correct in ila interface (in term of timing and information), but when i want to read data, i don't see anything.
