How to store program after power-off in FPGA?

[Clarissa]

I'm using the Nexys Video board, and I followed https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-programming-guide/start this tutorial and use JTAG to program it. However, data and program are lost when power is off and I have to re-configure the board. What should I do to have the program launched automatically every time the power is on? 

Through the tutorial mentioned above, I understand that I need a Quad SPI Flash, should I just follow the section N°5?

By the way, once the program is stored, how to modify? If I use a QSPI flash, do I just need to create a new bitstream and repeat the instructions in section n°5?

Hey @Clarissa,

You are right. You need to just follow section No 5. After you stored the program, if you want to modify it, you need to create the new .bit and repeat the instructions.

Best regards,
