kernel init problem

Hi Heing and Hippo,

I need some more understanding on this topic,

If my nios2_system.h has following

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

----------------------------------------------------------------------------

# define na_high_res_timer 0x809209e0# define na_high_res_timer_irq 3

# define na_sys_clk_timer 0x80920940# define na_sys_clk_timer_irq 0

/* Redefining high_res_timer -> timer0 */# undef na_high_res_timer# undef na_high_res_timer_irq

# define na_timer0 ((np_timer*) 0x809209e0)# define na_timer0_irq 3

------------------------------------------------------------------------------------------[/b]

--- Quote End ---

Does this means even na_sys_clk_timer_irq number is 0 (Zero), na_sys_clk_timer_irq is not been used as timer0.

And due to same reason I am facing following crash
