10. Click SOF Data, and select Add File, and select your .sof file

11. Click Add Hex data, select Relative addressing, and select your .hex file created above

12. Now push generate. You should verify that the generated .map file has Page_0 at a start address of 0x0, and the hex file at a start address 1 after the end address of Page_0

13. Now in the Quartus II Programmer, select Add File and select your .jic file. Check the Program box next to the .jic file, and push Start

Creating the .jic file:

In Quartus, open the Convert "Programming File..." utility

Set the "Programming file type:" to "JTAG Indirect Configuration File (.jic)"

In "Input files to convert" select "Flash Loader", click "Add Device..." and choose your target FPGA device

If you are configuring the FPGA from the serial flash:

In "Input files to convert" select "SOF Data", click "Add File..." and select your FPGA .sof file

-With "SOF Data" selected, click "Properties", in the "SOF Data Properies dialogue box:

-Set "Address mode for selected pages to" to "Start"

Set "Start address (32-bit hexidecimal:) to 0x0.

In "Input files to convert" click "Add Hex Data", in the "Add Hex Data" dialogue box:

Set "Addressing mode" to "Absolute addressing"

Select your hex file using the "..." button next to the "Hex file" field

Click "OK"

Check "Create Memory Map File". This is useful for debugging.

Generate the .jic file and program it into the serial flash with the Quartus Programmer

3.3.1.3 EPCS Parameters

3.3.2 Programming Both Hardware and Software into an EPCS/EPCQ

Device

The --base parameter is not available for EPCS/EPCQ devices, because in EPCS/EPCQ devices, FPGA configuration data must start at address 0x0. However, if you are programming both an FPGA configuration and a Nios II software executable in the EPCS/EPCQ device, the --after parameter lets you position the software executable directly after the FPGA configuration data.

Convert the FPGA configuration file first using sof2flash. When converting the Nios II software executable, use the --after parameter, and specify the FPGA configuration S-record file. The S-record output for the software executable starts at the first address unused by the FPGA configuration. Refer to the second example under the “elf2flash Command-Line Examples” chapter.

Note: elf2flash does not insert the FPGA configuration into the output file. It simply leaves space, starting at offset 0x0, that is large enough for the configuration data.

Note: In Intel Quartus Prime software version 13.1 and onwards, the -epcs/--epcq option in sof2flash generates .flash file with a SOF header, which contains the SOF length.

This change is required for V-series devices and above for new SOF format, and to allow for future SOF format variations. The Nios II bootcopier loads the Nios II software executable from EPCS/EPCQ devices based on the SOF length. For more information about how to program EPCS/EPCQ devices, refer to the "KDB Solution rd11192013_118" webpage.

char * const a;

means that the pointer is constant and immutable but the pointed data is not.

You could use const_cast(in C++) or c-style cast to cast away the constness in this case as data itself is not constant.

const char * a;

means that the pointed data cannot be written to using the pointer a. Using a const_cast(C++) or c-style cast to cast away the constness in this case causes Undefined Behavior.
