How to program application image address in flash with Arria 10GX RSU IP?

Hello, I am able to program the flash with application image using the GSFI IP. But then, I notice that the application address in the first 20bytes of the flash is set to 0x4000_0000. I am not ...

Hi


First you would need to flash an initial image that will set the location of the images.


https://www.intel.com/content/www/us/en/design-example/714766/arria-10-intel-fpga-remote-system-update-via-pci-express.html


Please refer to the section 3.5 of creating an initial image that will allocate the images location.

This is done by using the Convert Programming File tool.


You need to allocation the image location in the tool. Once generated the initial image and flashed on the board, only then the RSU will get the image from the location.


You could try out the example design in the link above.

Please note that the example design was created on the Centos OS.

Thank you for trying. This doesn't answer the question though.

I am asking when does RSU IP block update the image offset at location 0x10 in the flash so that next time the FPGA loads the configuration bitstream from that location.

Register 3 specifies the address of the boot image. But writing to it doesn't update the flash.

Thank you.

Best regards.
