Board Update Portal Instructions

The Board Update Portal allows you to write new software image to user software portion of flash memory.

Select files required to update the board

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

    elf2flash --base=0x24000000 --end=0x27FFFFFF --reset=0x24430000
    --input=yourfile_sw.elf --output=ext_flash.flash
    --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec/strong>

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, move the BOOT_SEL (SW2.2) to OFF position(1), then press button PULSE_NCONFIG (S5) or power cycle the board to configure the FPGA from DUAL COMPRESSED IMAGE #1.
  4. Ps: Please make sure user FPGA build has already been programmed into DUAL COMPRESSED IMAGE #1 section before it boots up from user software image.
