linux kernel execution problem for ARMv8 in big.LITTLE mode

[HADOUDA]

Hello;
Help me please
I run Linux kernel for ARMv8, I opened two terminal;

I typed in the first terminal the following command:

sudo build / ARM / gem5.opt configs / example / arm / fs_bigLITTLE.py --cache --kernel = / media / ali / ali / gem5 / linux-arm64-gem5-gem5 / vmlinux --boot = / media / ali /ali/gem5/system/arm/aarch64_bootloader/boot_emm.arm64 --dtb = / media / ali / ali / gem5 / system / arm / dt / armv8_gem5_v1_big_little_2_2.dtb
I found the following result:

Global frequency set at 1000000000000 ticks per second
info: kernel located at: /media/ali/ali/gem5/linux-arm64-gem5-gem5/vmlinux

and when I typed in the second terminal the following command:
telnet localhost 3456
I found this result without executing the kernel:

Trying 127.0.0.1 ...
Connected to localhost.
Escape character is '^]'.
