nios ii flash programming error

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

Something wrong with me?

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.

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?

Hi！ I have the same problem!!

Have you solved this problem?

My flash is set the 8bit databus connect to FPGA(EP2C5),when 16bit databus is no this problem.

further more this problem usually appear when I compile the code and first download the .elf; when I download the same .elf to the flash in the secondtime ,it works.

This is very strange!!

The secondtime download ,it works:
