NRV_RESET_ADDR into SPI Flash does not work #28

Closed BrunoLevy closed 3 years ago

BrunoLevy commented 3 years ago

NRV_RESET_ADDR seems to be ignored, the device still starting from address zero. Do we need longer inititialization time for the BRAMs, or is it something else ?

Fixed by using always @(negedge clk) in the new mapped SPI flash controller.
