Hyperflash write commands not recognised

Hyperflash is not responding to any commands except status register read. I tried word programming , buffer programming, sector erase, Chip erase, DeviceID reading but none of this worked. Everytime status register value remains 0x80.

 

Can someone tell me what could be the issue.?

Hi, 

Thanks for the response.

Even word programming and buffer programming do not work. 

I get 0x48E5 every time I try to read from base address except in status register read(0x80).
