    FX3 SPI FLASH using Adesto FLASH




      I am facing some issues with the AT25DF041B-MAHN-T  and the SPI boot option of the FX3 device.


      AT25DF041B-MAHN-T shall be a replacement of the M25P40 PN. The issue is that I am able to burn the image into the FLASH but the FX3 is falling into USB boot mode despite PMOD are properly configured.


      MISO/MOSI has not any pull up/down resistor and MISO, MOSI, CS# and CLK are properly routed to the FX3, HOLD# ping and WP# are tied VCC (3.3V).


      Can someone help me to find the issue?




      Best Regards,
