Generating Flash Programming file using sof2flash - Generating Flash Programming file using sof2flash Hi, I am working with Agilex device AGIB023R31B1E1VB. The FPGA is connected to to a QSPI Flash MT25QU02G. I want to use an external programmer tool and understood that I need to use the sof2flash utility. I run the following : sof2flash --offset=0x0 --input=standard.sof --output=standard_cfi.flash And I get the following error: file not found or not valid The file exist and i am running the command under the correct directory. Nov 12, 2024 3:25:57 PM com.altera.commandApplication.CmdApp severe SEVERE: sof2flash: Input file, not found, or is not a valid SOF file. Used the following version: ------------------------------------------------ Altera Nios2 Command Shell Version 23.4, Build 79 My question: Does Agilex SOF file conversion is supported? Does MT25QU02G is supported in sof2flash command? Are there any other ways to convert it?

Replies: Re: Generating Flash Programming file using sof2flash Hi Shaul, Thanks for the reply , understood why you need the srec instead of using JIC. If there is no further question related to the case , I will set this thread to community support. Thanks Regards Kian Replies: Re: Generating Flash Programming file using sof2flash Hi Kian, Yes that's understood. Using n ios2-elf-objcopy can give the same output as sof2flash by using ' srec' format. I know JIC is best to program the Flash by JTAG b ut we have another hardware option to implement Flash programming using external host (and I don't mean remote update) without involving the FPGA . something like this: So thank you for the information about sof2flash issue and obsolete n ios2-elf-objcopy in the future. Shaul Replies: Re: Generating Flash Programming file using sof2flash Hi Shaul, From the sof2flash description, it will generate a s-record/srec file output I saw that is one KDB on converting , but I'm not sure whether it supports your flash size density , but you can try if needed and change the EPCQ. https://www.intel.com/content/www/us/en/support/programmable/articles/000077309.html https://www.intel.com/content/www/us/en/docs/programmable/683689/current/nios2-elf-objcopy.html Alternatively I was talking to our engineering, since niosII is obsolete and removed from newer Quartus Pro version, tools such as sof2flash & n ios2-elf-objcopy also been removed , the recommended approach for programming SOF into QSPI is to use JIC file instead. Thanks Regards Kian Replies: Re: Generating Flash Programming file using sof2flash Thanks Kian, Meanwhile it looks like nios2-elf-objcopy command works with RPD file conversion. Do you know what is the difference with sof2flash output versus nios2-elf-objcopy output. I mean what is actually the file format output of sof2flash because I can have different format conversion with nios2-elf-objcopy.

Please do allow me some time to check on the sof2flash and will revert back to you. Thanks Regards Kian
