Re: [microblaze-uclinux] Re: [uClinux-dev] interrupts - how to use for user IP

[devi <devi@xxxxxxxxxxxx>]

Hi,

This is the portion of Interrupt Controller for irqs...

BEGIN opb_intc
 PARAMETER INSTANCE = InterruptController
 PARAMETER HW_VER = 1.00.c
 PARAMETER C_BASEADDR = 0xFFFF_3000
 PARAMETER C_HIGHADDR = 0xFFFF_30FF
 BUS_INTERFACE SOPB = myopb
 PORT OPB_Clk = sys_clk
 PORT Intr = ps2irq & ethernet_int & uart_int1 & uart_int & xtimer_Interrupt
 PORT Irq = mb_irq
END

Is the change in request_irq alone will suffice or should i increase no. of interrupts...
 
Thanks & Regards,
Devi
