Write-protect configuration flash memory with Quartus Prime Pro Programmer

In our design we use a Micron MT25QU256 flash memory device to hold the configuration for the Cyclone 10 GX FPGA. We are going to load a factory image and an application image into this memory, and...

Hi Paul,


The Programmer can not implement the image protection by itself.

Generally, the protection of Factory Image is implemented by setting a fixed address to user application.

As you said, there's a Serial Flash Interface IP that can implement this write-erase protecting feature to certain vector range. Is it what you are referring to?

Also, are you using .jic or .pof for configuration?


Thanks & Regards,

Xiaoyan

    Hi Xiaoyan,

    I was planning to use the ASMI Parallel IP core, which implements protection for various ranges of sectors, starting with a single sector up to the entire device. Does the Serial Flash Loader support implementing write protection? As far as I could see, it is a logic bridge between the JTAG and AS interfaces. Perhaps there is a specific set of JTAG commands that would allow write-protection to be set on the flash memory through the SFL? We're using a .jic for configuration of the flash over JTAG.

    Thanks for your time on this.
