Board Update Portal Instructions

The Board Update Portal allows you to write new designs to the user hardware 1 and user software portion of flash memory.

Select files required to update the board

Convert user .sof file and .elf file to 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, open Nios II Command Shell

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

    sh build_hw.sh yourfile_hw.sof 1

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

    elf2flash --base=0x0 --end=0x0FFFFFFF --reset=0x06700000
    --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

  1. Browse to the hardware file and the software file (if required), respectively.

  2. Click Upload, and then wait for the files to be written to flash. Progress is displayed from 0 to 100%.

  3. When the upload is complete, Press button PGM_SEL (S2) on the LED daughter board until LED D2 is lit then press button PGM_CONFIG (S1) to configure the FPGA with the new image.
  4. Or move the DIPSW factory_load(SW3.3) to user position(OFF), then power cyle the board to configure FPGA from user portion of the flash.
