Can not type anything from the Linux prompt

Hi, I used the linux version from the Speedway lab of Zedboard.org and changed the u-boot configuration file(Zynq_zed.h), devicetree(dts), and kernel configuration file(Xilinx_zynq_defconfig) so that they match the differences on the board designed by myself (uart0 and 256MB lpddr2).

This version previously worked well on the Zedboard. But right now, on my board, I can only see the Linux prompt and can not type anything into the console. It looks like the priority of UART port is being occupied by something else.

What's the possible cause?

Thanks in advance.
