Nios2 + rocket boards linux-socfpga = terminal trouble

Hello, Dear All!

I am trying to launch linux on nios2 soc. I used Altera DE5 board and these instructions:

I used the next tools:

  • toolchain Sourcery CodeBench Lite 2014.05-47
  • linux-socfpga kernels 4.4 and 4.7
  • buildroot 2014.02

After configuring FPGA, loading kernel and launching nios2-terminal I saw from jtag-uart messages about succesfull kernel loading and offer to enter login. But when Im trying to enter login (root), nothing happens. It seems like some problems with terminal. Could anybody help me with this issue?

Here you can download the terminal output, *.dts file and .config file for the kernel:
For buildroot I used this config from the first link.

Thanks in advance for any kind of help!

I dont use etc/securetty. At least, I dont see it in my buildroot/output/target/etc
In buildroot setting I checked “run a getty (login prompt) after boot” (ttyJ0 port, 115200 baudrate) and “Enable root login with password” with empty pass. Init system - Busybox.
When I see login prompt I’ll try to enter “root”. But I dont see characters that Im typing.
