Hello

Thanks for your reply

True But Flash address bus A0 to A24 is connected With CPLD CEn and OEn, pins and also

One 12 bit Data Bus connected between CPLD and FPGA

My question is If we want to use Cpld as a flash programming first Load SOF in Fpga to connected Flash Data Bus to CPLD data Bus also WEn pins

Maybe CPLD will work as a flash Programing

What would you say ?

Thanks
