Board Update Portal Instructions

Select files required to update the board

• SRAM Object File (.sof) containing the FPGA image
• Executable and Linkable Format File (.elf) containing the software application
  (required only if the design includes a software application)

Convert the .sof file and .elf file to flash format (that is, the format required to program the flash)

Note: You must have the Nios^® II EDS installed in order to perform this step.

1. From the Start Menu select All Programs, Altera, Nios II EDS, and then Nios II Command Shell

2. In the Nios II Command Shell, navigate to the .sof file and type
   

   sof2flash --input=yourfile_hw.sof --output=yourfile_hw.flash
   --offset=0x640000 --pfl --optionbit=0x18000 --programmingmode=PS

3. If the design includes a software application, in the Nios II Command Shell, navigate to the .elf file and type
   

   elf2flash --base=0x08000000 --end=0x0BFFFFFF --reset=0x0A020000
   --input=yourfile_sw.elf --output=yourfile_sw.flash
   --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec

Program the flash and reset the board

• Browse to the hardware file and the software file (if required), respectively. Click Upload, and then wait for the files to be written to flash. When the upload is complete, set dipswitch SW4.4 on the board to the "1" position. Cycle power switch SW1 to configure the Arria II GX device with the new design.
