- Subject: [ECOS] why not interrupt?
I try to write a mouse driver for ecos(i386).I meet a
problem, I can't make my interrupt routine response
the interrupt.my code is bleow,please give me some
advice.
#define MOUSE_BASE 0x300
#define MOUSE_IRQ CYGNUM_HAL_INTERRUPT_COM2 //35
static cyg_uint32 isr(cyg_vector_t
vector,cyg_addrword_t data)
{
return 1;
}
static int mouse_lookup()
{
............
cyg_drv_interrupt_create ( MOUSE_IRQ, 99, 0, isr,
mouse_interupt, &interupt_handle, &interupt_obj);
cyg_drv_interrupt_attach (interupt_handle);
cyg_drv_interrupt_unmask (MOUSE_IRQ);
..............
}
static void mouse_interupt(cyg_vector_t vector,
cyg_ucount32 count, cyg_addrword_t data)
{
.............
}
static int mouse_read(cyg_io_handle_t handle,void
*buf,cyg_uint32 *len)
{
.......................
}
I set breakpoint in my DSR and ISR routines,but it
never reach the breakpoint!
I also tried to use timer interrupt(32) as interrupt
vector,it doesn't work too.
