I think the boot from fpga is behave a such right? do we have a method to boot completely from fgpa it self without rely on the SD card?

how can I have a method that completely place all the boot related files in the fgpa, similar like boot from qspi method?

so far there is no example for such implementation for FGPA side as i know, since you wanted to be SD card physical free, just use the qspi mode, as also having the same structure like SD card.!

any weak point that using qspi? what is the benefit if using qspi over sd card?
- Altera_Forum
the first benefit for using qspi is faster boot up time!

another good thing is reduce space as the SD card sloting area is occupied some space are.a
- Altera_Forum
then i should try with the boot from qspi...

for me the boot for qspi or sd card is the more convenient configuration usage to me. as FGPa one is not keeping all resource in same location
