I have EDK project running in ML403 board and It contains PowerPC. I wanna to download my system onto board's Platform flash memory so that I can reprogram -after repower on- my FPGA from This Flash Memory whithout connecting the board to my PC again.
Please can you guide me for tutorial which describe this feature because every tutorial I found describe only how to download the software file (ELF file) only. But I need to download both system bit file (download.bit) and the software file (ELF). and how can I connect them so that the ELF file run automatically.
Thank you in adance. You're very kind.

Thank you for your submission
But I wanna to generate the appropriate files for Platform Flash Memory not for FlashACF which you concern.
What about generate ELF and Bit to MCS.

I hope you know bootloading in EDK. Moving on from here...
In bootloading the penultimate step just to the last step is the programming of FLASH with the ELF file.
Once thats successful we update our bitstream with the bootloader generated as the last step.
Then we download this inside FPGA and then the bootloader reads data from FLASH and executes from external RAM, SRAM or SDRAM.
This is the only downloading we have to do manually, so if we generate the .mcs file corresponding to this .bit file and burn a PROM then we don't have to do even this much also.
Data is permanently there in FLASH and PROM will download bitstream in FPGA so in such a case i think that everything will start-up at power on.
Above stuff i haven't tried but just thought of it.
