A.2. Preparing Design Files for Flash Programming
The following sections use the following file types:
- Nios® II Flash Programmer File (.flash)
- Executable and Linking Format File (.elf)
- SRAM Object File (.sof)
- S-Record File (.srec)
You can obtain designs containing prepared .flash files from the Cyclone® V GT FPGA Development Kit page of the Intel website. You can also create .flash files from your own custom design.
The Nios® II EDS sof2flash command line utility converts your Intel® Quartus® Prime-compiled .sof into the .flash format necessary for the flash device. Similarly, the Nios® II EDS elf2flash command line utility converts your compiled and linked .elf software design to .flash.
For more information about Nios® II EDS software tools and practices, refer to the Embedded Software Developer Center page of the Intel website.
