    Hi Vasu,

    Try by going to the project folders > right-click > properties> Nios II Application properties >

    Debug Level = 2

    Optimization Level =2

    This gives the required output

Hi Anand,

Thanks for your support.

I have gone through your given design & noticed one difference in the eclipse project. I think you have used the template "hello world small" for eclipse project.

I used NIOS code(hello_sw_leds.c) from your design on MAX10 Deca board with BSP template "hello world" & observed wrong result(int = 0x44332211). In a similar way, I also checked NIOS code with "hello world small" template & got expected result(int = 0x66554433). This could be happened due to reduced driver size.

So with the above issue, I want your guidance on how we can get the expected output with "hello world" template in eclipse or in other words what settings need to be done in "hello world" project? Because we already design our project with "hello world" template.

I have attached screenshots of eclipse project for your reference.

Thanks,

Vasu.
