Hello!
I have 2 questions:
how can I program the FPGA definitively given an RBF file? (I ve tried to write it to the QSPI flash at address 0x800000 , I ve sent the prelaoder, as well at adress 0x0, but nothing happened, the FPGA still configured same old,) (I followed the instruction here
https://rocketboards.org/foswiki/documentation/gsrd131programmingfpga)
Why I lost control to my board when I program my FPGA via quartus programmer?
My board: Altera cyclone V SoC SX, with linux 3.7, ARM dual core A9
Thanks in advance

the way I program my FPGA is by taking the memory card from the FPGA insert it into the computer, then I replace the RBF file available in the memory card. I put the sd card back into the FPGA and restart. the preloader will load the new configuration automatically.
if you do it.
you can also program the FPGA from inside the Linux directly ( i did not try this but according to this page you sent ) start reading from 'FPGA Configuration from Linux'
programming the FPGA from Quartus programmer does work if you are using the reference design of your board and you did not change the memory addresses. otherwise, the Linux system will not be able to send commands to the right shared address. These addresses are mapped to hardware component connected to the FPGA part of the board.
this is what I know, hope this helps.
