sof2flash offset in EPCS mode

Hello, We would like to generate a .flash file from .sof file for EPCS device with an offset != 0x0. Apparently with the --epcs option the address in the .flash output file (srecord) is always set ...

Hi,


Maybe you could port one of the example design which is the RSU over UART with EPCQ:

https://www.intel.com/content/www/us/en/design-example/714988/cyclone-v-remote-system-upgrade-over-uart-based-on-nios-ii-processor-with-epcq.html


This uses the EPCQ boot copier method to program multiple application instances.


You need to refer here for the design of the EPCQ boot copier method:

https://www.intel.com/content/www/us/en/docs/programmable/683104/current/nios-ii-processor-booting-from-altera.html


Then refer to the example design doc on the programming files generation steps:

https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/horizontal/system-upgrade-over-uart-nios-ii.html


This may take some time to grasp if you're not familiar with the RSU.

    Hello,

    I am familiar with RSU. I already had a look at those documents.

    However I didn't find a way to generate a .flash file in epcs or epcq128 mode with an offset.

    Even with more recent version of Quartus.
