Parallel FLASH S29AL016J as an external memory to ADSP21369

Hi All,

I am using Parallel FLASH S29AL016J as a BOOT FLASH for ADSP21369 in my project. I am using Custom board which consists of ADSP21369 and SPARTAN7. FLASH chip enable is mapped to FPGA pins. ADSP will send some custom address, then FPGA has to select the chip enable pins. Same way for RD and WR pins. ADSP RD and WR pins are mapped to FLASH pins via FPGA pins. Every control is done through FPGA. But I am not able to program the FLASH. It is giving Error programming LDR file error. And also I am trying to read FLASH device ID, but not able to read. not able to access the FLASH. Could anyone please help me to correct this problem at the earliest.
