Hello,
we are using S25FL256SDPNFB000 flash for the purpose of storing data in it. It is interfaced with zynq controller.
I am not able to write and read from the SPI flash. This S25FL256SDPNFB000 flash is working in QSPI mode. But its not working as data flash(as miso,mosi). The HOLD and WP signals are not connected to SPI controller in the zynq in DATA flash mode(not in QSPI MODE). Normally WP and HOLD signals are at 3.3v.Why it is not responding in data flash(4 bit interface)mode?
Regards,
Geetha
