Nios on DE0-Nano-SoC

Hello,

i have question about Nios on Cyclone V on development board DE0-Nano-SoC. I have design with some input/output pio, timer and nios processor, short program and i download bitstream and elf in command line - nios2-download -g test.elf. It goes ok, but when i try to run nios2-terminal, it failed with message No jtag uart was found.

How can i connect ? (i tried nios2-terminal --device 2 or nios-terminal --cable "De0 Soc Uart", but without success)
