Hi @mmdsaifudn,

Welcome to the Digilent forums!

I havent used the XIP more in the QSPI FLASH IP Core.  Here is a tutorial for using the QSPI FLASH IP core. The tutorial explains how to compress the bit file as well as commenting out the verbose serial print to reduce the time it takes to configure the fpga from the QSPI Flash. Have you already compress the bit file and commented out the verbose? This improved the time it took to configure the fpga from the QSPI Flash significantly for my projects.

best regards,

Jon

I did the compression and the commenting verbose.But still it takes huge time to load elf from flash.FPGA programming from  flash is happening fast.
