QSPI flash device Reset Pin

Hi all,

       I'm using VCU118 kit. In this i'm trying to access the QSPI flash device(U133). Is it possible to control the QSPI device Reset pin from the QSPI controller? At preset reset pin is not connected to anything, there is a DNP resistor to it. If we place this resistor, it will get connected to FPGA_INITB pin. My question is, can i control this pin from QSPI controller or any other means?

 

      Why i'm trying to control the reset pin is, i'm facing an issue in accessing the device in QUAD mode. With Power On i'm able to access the device in single and dual mode. But, i'm not able to access the device in QUAD mode. Please give some suggestions.

 

Thanks.
