Warm reset of NIOS under IDE

Hi,

I am trying to make a warm reset with NIOS II CPU. I just make an asm jump to the _start function. If I do this, I loose the control of IDE - I couldn't debug the source code any more. I just thought my program would start agian and would run to main program to my first breakpoint.

Did anybody know what is going on there?

Thanks for help,

Holger

    Hi,

    Base on my study, I find that Nios will initialize many global variables. Then if you reset system by just simply jumping to _start, some golbal will be re-initializing to a wrong value, so that you will lose control of IDE.
