NiosII, No ELF file path has been selected

Question

Hello everyone ,

I written a PID controller in NiosII, hello_world_small,yesterday, and everyting was OK.

I change some codes just now, and I get message :

Errors(3 items)

address 0xbfdc of PID1.elf section,'bss' is not withinregion'onchip_memory'

address 0xbdfc of PID1.elf section ,'onchip_memory' is not within region'onchip_memory'

make:***[PID1.elf]Error 1

And I check the Run configurations,the message is :

No ELF file path has been selected.

What's going on?:( How to generate the ELF file?:confused:

Could you please give a Screenshot of your QSYS-System and from the configuration of the NIOS inside the QSYS-System?

I think there could be the Problem.

If not, please send a Screenshot of the BSP-Editor (Linker-Script-Tab).

If your Project is error free, then an elf-File will be created and could be seen under Run Configurations.
