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.

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 ?
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 ?
