i have the zedboard development board,running Linux system (4.6.0)。Four uartlite IP cores are used in block design.in the /dev,we can see ttyUL1, ttyUL2, ttyUL3, ttyUL4, and ttyUL4.When I use the command echo 1 >/dev/ttyul1, I can receive data on the serial terminal. But when I send data using a serial termina,cat /dev/ttyUL1 receives no data.
cat /proc/interrupts
my devicetree

I've solved this problem。because in the dts file ,uartlite interrupts num is not right.

In4, irq id is 65, interrupt num is 33;
In5, irq id is 66, interrupt num is 34;
In6, irq id is 67, interrupt num is 35;
In7, irq id is 68, interrupt num is 36;
In10,irq id is 86, interrupt num is 54;
Refer to the table below。
if your uartlite@42c40000 interrupt connect to In4, in dts file, node of uartlite@42c40000 should be
serial@42c40000 {
...
interrupts = <0x0 33 0x1>;
...
};

Hello..
My issue is resolved with uartlite's thank you very much.
One more issue i have with axi-gpio . in my design i have 17 gpio's. for this i need to connect interrupt's for GPIO.
i made my dtsi like how you spefied the interrupt connection table . But interrupts for the GPIO are not enabling is there any thing i need to do in .dtsi ?
Please find the attachements ?
1.pps_in(0x4126_0000)
2.pps_out (0x4122_0000)
3.irnss_pps(0x4125_0000)
remaing Axi-gpio i connected without interrupt . can please help me with this ?
Shall i need to change any thing in kernal for this Gpio interrupt enableing ?
