Hi Paul,


As for your question about Serial Flash Interface IP, you may check the "Generic Serial Flash Interface Intel FPGA IP User Guide". In the Chapter 1.8, there's an example of how to protect certain sector range of FLASH, which is based on a platform built with this IP.

You may check this chapter first and see if it is helpful.


Thanks & Regards,

Xiaoyan

    Hi Xiaoyan,

    I had a quick look, it seems like it might work. I could connect the serial flash memory to the JTAG interface using the JTAG to Avalon bridge and the Generic Serial Flash Interface IP. Then I could run a TCL script in the Quartus System Console that is able to access the registers on the Avalon bus, including the control and status register that sets the protection.

    Does that sound right to you?
