hi there. I had some problems with the flash on a dev board. I solved it by editing the .v file of the system with the following lines ( I added the Reset and Write protected signal)
Hope it's useful. regards, Alexmodule flash ( // 1) global signals: clk_0, reset_n, // the_tri_state_bridge_0_avalon_slave address_to_the_cfi_flash_0, read_n_to_the_cfi_flash_0, select_n_to_the_cfi_flash_0, tri_state_bridge_0_data, write_n_to_the_cfi_flash_0, reset_flash, wp_n_flash ); output reset_flash; assign reset_flash=reset_n; output wp_n_flash; assign wp_n_flash=1'b1;
