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 to 0x00000000.
Is there a way to specify an offset address?
The purpose is to generate .flash file for Application FPGA image. We have another Factory image located at address 0x0 in EPCS flash.
Thanks

Hi,
Is it a Cyclone III device? Which Quartus version are you using with that?

Hi,
I think this document can help you. You can specify the offset address by setting up [--offset=addr] . Please take a look on it for better explanation.

Hi,
Maybe you could port one of the example design which is the RSU over UART with EPCQ:
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:
Then refer to the example design doc on the programming files generation steps:
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.
