Hi

Sir

Thanks for your reply

In my case I wrote my above post our custom board doesn't have directly CPLD to CFI data port there

thats why I am confused how to define PFL_flash_data [0] to PFL_flash_data[7] in PFL? CFI flash D15 also connected with CPLD.

PFL_flash_addr[0] to PFL_flash_addr[24] CPLD to CFI connected there

all require another pin connected between CPLD and CFI Flash like nce,we,oe etc

Thanks
