00. Using QEMU

• QUEMU Windows installation (in Russian)

• Using MIPS32EL ALT Wrikstation linux distro

  • Distro qemu image

  • staring qemu:

      $ qemu-system-mips64el -kernel vmlinuz -append "console=tty0 root=/dev/sda rootwait " -m 2G -serial stdio -drive file=0.img -device virtio-keyboard-pci -net nic -net user,hostfwd=tcp::2270-:22 -cpu mips64dspr2 -vga std -display gtk -device usb-mouse

  • starting from windows:

      C:\Program Files\qemu> qemu-system-mips64el.exe -kernel C:\Users\username\Downloads\vmlinuz -append "console=tty0 root=/dev/sda rootwait " -m 2G -serial stdio -drive file=C:\Users\username\Downloads\0.img -device virtio-keyboard-pci -net nic -net user,hostfwd=tcp::2270-:22 -cpu mips64dspr2 -vga std -display gtk -device usb-mouse

  • Graphcal mode

    • Using geany as IDE

    • Compiling and running.c-file by hand from terminal command line

      •     $ cc file.c
            $ ./a.out

        or

            $ cc file.c -o prog
            $ ./prog

  • Using ssh: hostfwd=tcp::2270-:22 means that connecting to host port 2270 is redirected to 22 port of virtual machine

    • Windows:

      • Install Git command line for windows

      • Clock Git bach here anywhere at file browser

    • ssh -oHostkeyAlias=mips user@localhost -p 2270

      • answer "yes" if connecting for the first time
      • password: user
    • Console editors:

      • vim ( do not try if you don't know what it is; at least passing through https://www.openvim.com/ is previously recommended]]

      • mcedit

• Translating to MIPS assembler language

  •   $ compile file.c

    • compile is a script, will be explained later

    • most of unknown .something strings are special GNU assembler directives, ignore it
