uartlite Rx can't receive data

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

Re: uartlite Rx can't receive data

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