Read/Write to Serial flash EPCS MT25QL128ABA1ESE

Hi

i am using a custom designed board from with CYclone10LP devices.i have connected serial flash (MT25QL128ABA1ESE) to the device to be used both as configuration data(.sof .hex ) and some user data to be stored in the same flash.

i have connected serial flash controller in the platform designer. i am able to program the flash and boot from it.

when i am trying to access the flash from my application ,i am failing to open the device file to write into it. "alt_flash_open_dev" is returning null.

this is the same procedure i followed for EPCS flash when when i was working with cyclone iV devices. can you help me where i am wrong?

thanks.
