nios ii flash programming error

[Altera_Forum]

Hi: 

When I program *.elf to flash ,there something wrong with it. The infomation like  # !/bin/sh# # This file was automatically generated by the Nios II IDE Flash Programmer.# # It will be overwritten when the flash programmer options change.#  cd E:/altera/80/workplace/RA8835/hello_world_1/Debug# Creating .flash file for the project "$SOPC_KIT_NIOS2/bin/elf2flash" --base=0x00200000 --end=0x3fffff --reset=0x20000 0 --input="hello_world_1.elf" --output="cfi_flash.flash" --boot="E:/altera/80/ip /nios2_ip/altera_nios2/boot_loader_cfi.srec"# Programming flash with the project "$SOPC_KIT_NIOS2/bin/nios2-flash-programmer" --base=0x00200000 --sidp=0x000010b0 --id=148608136 --timestamp=1252545047 --instance=0 "cfi_flash.flash" Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x000010B0: verified : Checksumming existing contents  00000000 : Reading existing contents  00004000 : Reading existing contents  Checksummed/read 7kB in 0.2s  00000000 ( 0%): Erasing  00004000 (66%): Erasing  Erased 24kB in 0.4s (60.0kB/s)  00000000 ( 0%): Programming  00004000 (66%): Programming  Programmed 18KB +6KB in 0.3s (80.0KB/s)  Verify failed at offset 0 Verify failed at offset 4000 Leaving target processor paused     //end Who can help me resave it?Please!  Thanks

I think you have to set the proper offset for the flash. It is 0x20000. 

 And also check whether you reset address in the SOPC builder system (cpu configuration) points to your flash.

[Altera_Forum]

The offset for the flash must be 0x20000 ? Thanks I will try！

[Altera_Forum]

I have checked it,but when I run Auto-Assign-Base Address,the offset for flash will be set as 0x200000 and end address 0x3fffff. 

And I have also checked that my reset address in the SOPC builder system points to my flash! I think the information when I program show that the nios(cpu) has found the flash device!

[Altera_Forum]

Obviously the NIOS isn't able to program the flash. 

 Either: 1 - The interface to the flash is bad (like incorrect connections, pin assignments, not meeting timing, bad timing parameters etc.) 2 - The flash is write protected. 3 - The flash is corrupt.  Jake

Sure looks like it. 

 Oh I just remembered something. What flash device are you using. I know starting with version 7.1, the flash programmer started having problems with some Intel flash parts. Are you perhaps using a J3v.D Intel flash part?  Jake

[Altera_Forum]

No,Because I test it with one project ,it shows us the information :

Shenhuan, 

 Maybe I explain this incorrectly, but I meant flash offset - Offset within the flash memory device where the FPGA configuration is to be programmed, not the base adderess of the Flash in the SOPC builder system. The offset is the relative address within the memory device where the configuration image is located. it is done in the flash programmer dialog window of the NiosII EDS or in the command line it is for example: sof2flash --activeparallel --offset=0x20000 --input=niosII_lab.sof --output=hardware_image.flash So you will have  # Creating .flash file for the FPGA configuration "$SOPC_KIT_NIOS2/bin/sof2flash" --offset=0x20000 --input="C:/Trainings/nios_II_lab/niosII_lab.sof" --output="niosII_lab.flash "  Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert    # Programming flash with the FPGA configuration "$SOPC_KIT_NIOS2/bin/nios2-flash-programmer" --base=0x01000000 --sidp=0x02401098 --id=43463617 --timestamp=1248819551 --instance=0 "niosII_lab.flash" Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x02401098: verified   : Checksumming existing contents    etc this specifies hardware-image region of the flash memory.   Maybe this is not your case, but its worth to try to play with it. What offset are you specifying now? 

[Altera_Forum]

uilka_b, 

Thanks for your explanation. I know the offset means you told,but I am programming *.elf to flash not FPGA configuration file,so my flash base address is 0x200000. I set the Nios II Processor in the sopc_builder system like this: Reset Vector: Memory:cfi_flash Offset:0x0 (Do you mean this place should be set as 0x2000??) Exception Vector: Memory: sram Offset:ox20 //end shenhuan:)

[Altera_Forum]

I thought you program both sof and elf to flash. 

 So I meant offset to specify hardware image region in the flash memory. not addressing in the SOPC builder system. Please describe step-by-step how you run your project in the board and how you configure your flash.

[Altera_Forum]

I program sof to EPCS4 first ,and then program *.elf to flash by NIOS_IDE_flash_programmer. 

Something wrong with me?

[Altera_Forum]

Can you provide more details?

[Altera_Forum]

First ,in a new project,I build a sopc_builder system,and add CPU,tristate_bridge,cfi_flash,sram and some PIOs. 

In nios_processor setting ,reset vector set as cfi_flash, offset set as 0x0 ,then run Auto_assign_Base_address and Auto_assign_IRQs in System_view, last I generate the nios_system. After generate OK and assign Pins OK! I compile quartus_project! Then open the nios_ide,build software_project,set system_library_propetities, compile system.When does this OK,I program quartus_project first and then program elf to flash by NIOS_TOOL_FLASH_PROGRAMMER.

[Altera_Forum]

Have you tried to run your program without using the flash? 

Just normally after programming hardware, launch Run as-> Nios II hardware. Does it work?

[Altera_Forum]

Yes ,it works well!

[Altera_Forum]

What hardware do u use? A dev-kit or your own PCB?

[Altera_Forum]

My own pcb!

Hi！ I have the same problem!!

The secondtime download ,it works:

@shiy 

I also have the same problem ....Can you please me tell me how you solved the problem....
