LS1046 IRQ1 Interrupt Error

Hello,

 

I am using the LS1046A custom board.

IRQ1 is tested by referring to the following link. 

https://community.nxp.com/t5/Layerscape/Howto-access-IRQ0-on-a-LS1046a/m-p/779140 

 

However, insmod kernel panic occurs.

I need help.

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

cpld: board-control@2,0 {
compatible = "fsl,ls1046ardb-cpld";
reg = <0x2 0x0 0x0000100>;

interrupts = <GIC_SPI 164 IRQ_TYPE_LEVEL_LOW>;
interrupt-parent = <&gic>;
status = "okay";
};

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

node = of_find_node_by_name(NULL, "board-control");
irq_num = of_irq_to_resource(node, 0, &resource);
ret = request_irq(irq_num, (irq_handler_t)sio_interrupt, IRQF_TRIGGER_RISING, "irq1_handler", NULL);
if (0 > ret)
{
printk("unable open IRQ (%d) : %d\n", irq_num, ret);
return ret;
}
printk("IRQ num=%d\n", irq_num);

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

How do you define the interrupt handler sio_interrupt?

Would you please provide your source code(C file, Makefile and dts file)?

I will do verification on my target board.

Hello yipingwang,

I solved the problem.

When I changed the GIC_SPI IRQ number from 164 -> 132 in the fsl-ls1046a-rdb.dts file, it worked normally.

interrupts = <GIC_SPI 132 IRQ_TYPE_LEVEL_LOW>;

However, I don't understand why the irq must be entered as 12 value for request_irq to work.

Thank you!

Best Regards,

Gyosun.
