memory read failure

[Renuka]

hi 

I am using M95512 512kb EEPROM connected to FPGA via SPI 

when Iam writing and reading the data (in single address(0000)) below sequence is followed

step 1: wren instruction is sending.(06)

step 2: write data to memory array.(02)

step 3: check WIP status (05)

step4: read the data from memory array. (03)

repeating all four steps repeatedly sometimes FFFF values are received from memory, sometimes I am getting read data correctly. 

can you tell why data is not writing properly i

Bug in the code probably. Show it.

Oh, this is on an FPGA, which makes this more complicated. Still, a trace of relevant SPI lines or simulation result showing the in/correct behavior might prove insightful.
