.hex file generate for Nios-II C code

[Altera_Forum]

Hi, 

  I am using Quartus-II Version 9.1sp2 and i am also using Nios-II IDE Version 9.1. I have a Custom board with Cyclone-I FPGA EP1C12Q240C8N. I made Nios-II Base project using SOPC Builder and write a program for blinking LED in Nios-II IDE.   I am not using Flash programmer for loading Nios-II Program. I made .hex file of my C program from adding "mem_init_generate" in make target>>Build of Nios-II Project and add in Quartus-II. Problem is, after adding .hex file in Quartus-II, i update Memory Initialization file and reassemble the Quartus project, but then also my program not run. So please suggest solution for this problem.   Below is message of Nios-II IDE after Build project.  Post-processing to create mem_init/Program_Memory.hex... elf2hex STQFP.elf 0x00004000 0x00007fff --width=32   --create-lanes=0 mem_init/Program_Memory.hex Post-processing to create mem_init/hdl_sim/Program_Memory.dat... elf2dat --infile=STQFP.elf --outfile=mem_init/hdl_sim/Program_Memory.dat   --base=0x00004000 --end=0x00007fff --width=32   --create-lanes=0  Post-processing to create mem_init/hdl_sim/Program_Memory.sym... nios2-elf-nm -n STQFP.elf > mem_init/hdl_sim/Program_Memory.sym     Thanks  Nandish Jasani.

Hi, 

 try to append "--record=4" after "elf2hex STQFP.elf 0x00004000 0x00007fff --width=32" before the backslash (in your projects mem_init.mk file).   I have to do this for years, now. I don't know how other people get a working hex file out of the automatic Nios II build process. Once i regenerate my BSP, I have to add this line, again, because it overwrites the mem_init.mk file.  I'm not a "build process"- / make- /toolchain- /whatever-guru, so I was not able to find an automatic solution for this issue. I just take it as a little drawback of the tools which I found my own workaround for.  Please report, if it also solved you problem.  Regards, Maik

Thanks Maik, 

  I successfully appended “--record=4” in my make file, still I am facing the same issue.   What file should I add to Quartus-II Projects after make target (I have added .mk and .hex in Quartus-II Project according one of the altera forum threads)?   We have another custom board with Cyclone-IV and we are using Quartus-II Version 13.0 for different project. In Nios-II, make target generates .qip file which we added to Quartus project and the project works as required. So we tried similarly for Quartus-II Version 9.1sp2.   Below is the build message.  Post-processing to create mem_init/Program_Memory.hex... elf2hex STQFP.elf 0x00000000 0x00003fff --width=32 --record=4  --create-lanes=0 mem_init/Program_Memory.hex Post-processing to create mem_init/hdl_sim/Program_Memory.dat... elf2dat --infile=STQFP.elf --outfile=mem_init/hdl_sim/Program_Memory.dat   --base=0x00000000 --end=0x00003fff --width=32   --create-lanes=0  Post-processing to create mem_init/hdl_sim/Program_Memory.sym... nios2-elf-nm -n STQFP.elf > mem_init/hdl_sim/Program_Memory.sym   Regards, Nandish Jasani

Hi, 

 starting with Quartus 9.1 SP2, I got these hex file generation generation issues. Though I do not exactly understand what exactly your problem is.  What I have to do with this very version of the build tools is the following:  I generate a BSP project from my sopcinfo file. After that I generate a firmware project which refers to the just created BSP. All this I perform with the "Nios II Software Build Tools for Eclipse" Project Wizzard.  After that I do have to make two changes in the automatically generated make files.  The one is the change I posted above. The other is in the Makefile of the BSP in the line "CREATE_ELF_DERIVED_FILES := 1" which I have to set to one as shown here. This is responsible for creating the hex file at all. The --record=4 flag is responsible for the layout or alignment of the hex file.   If I follow these steps with the exact tools version you mentioned, then I can work with it succesfully for years, now.  Still, I'm intereseted in suggestions leading to a more convinient way to handle this hex file creation because as I said, once you run the BSP editor, you have to reset those settings in order to get your hex file.  I hope this helps.  Regards, Maik

As additional info, here is one of my hex creation build message that sucessfully creates a usabel hex file (one for onchip ram and one for onchip rom which contains the program data). 

 Post-processing to create mem_init/onchip_ram.hex... bash -c 'elf2hex e_fpga_0100_firmware.elf 0x00424000 0x00427fff --width=32 --record=4  --little-endian-mem --create-lanes=0 mem_init/onchip_ram.hex' `mem_init/onchip_ram.hex' -> `../../onchip_ram.hex' Post-processing to create mem_init/onchip_rom.hex... bash -c 'elf2hex e_fpga_0100_firmware.elf 0x00410000 0x0041c7ff --width=32 --record=4  --little-endian-mem --create-lanes=0 mem_init/onchip_rom.hex' `mem_init/onchip_rom.hex' -> `../../onchip_rom.hex'  Regards, Maik
