Hi ETang2

You could solve this error b increasing the OCRAM size in the Quartus project.

Once you do this you would need to regenerate the BSP again.

  Hi
  
  Would like to confirm with you are you trying out the boot method of OCRAM?
  
  https://docs.altera.com/r/docs/726952/25.3/nios-v-embedded-processor-design-handbook/nios-v-processor-booting-from-on-chip-memory-ocram
  
  From the view of your objdump, it seems like you did not select the OCRAM for all the fields in the linker in the BSP Editor.
  
  https://docs.altera.com/r/docs/726952/25.3/nios-v-embedded-processor-design-handbook/software-design-flow?tocId=LNK8n8wvHPseNjT2CnUU5A
  
  If you are selecting the OCRAM boot method, which boot method are you trying out?
  
  Regards

Hi

From the error log, it seems like the code that you have built have been flashed successfully into the device and it runs till the address 0x04000004 where it could not detect any code.

Could you share with us your objdump file of the application and a view of the address map and your NiosV parameters in the platform designer?

Regards

tehjingy
