About

This tutorial is an adapted version of NiosII Linux User Manual.

Download Mentor's compiler;
Download buildroot Embedded Linux Generator;
Create a work directory, e.g. "mkdir my_first_linux";
Extract bot files to my_first_linux directory as "sourcery" and "buildroot" respectively;

Go to the my_first_linux/buildroot/configs/ directory and run "wget https://rocketboards.org/foswiki/pub/Documentation/NiosIILinuxUserManual/nios2_defconfig";
Now edit this file with any editor like "vim nios2_defconfig";
At the third line, change the value of the variable 'BR2_TOOLCHAIN_EXTERNAL_PATH' to the path where you extracted the compiler, e.g: '/home/aluno/Documentos/sourceryg++-2016.05'.

Now go to the directory my_first_linux/buildroot/ and run "make nios2_defconfig";
After that open the config menu with "make menuconfig";
[Optional] Enter your root password at System Configuration -> Enable root login with password;
[Optional] Add OpenSSH at Target packages -> Networking applications -> openssh;
Select an text editor such as nano at Target packages-> Text Editors and viewers -> nano;
Exit & Save;
Run "make".

Go to the my_first_linux/buildroot/ directory and download the bootloader running "git clone https://github.com/altera-opensource/u-boot-socfpga.git";
Export the need environment variables in order to continue:
- export PATH=$PATH:/home/aluno/Documentos/sourceryg/bin (path to the binaries of your compiler)
- export ARCH=nios2
- export CROSS_COMPILE=nios2-linux-gnu-
To generate to bootloader, go to my_first_linux/buildroot/u-boot-socfpga/ directory and run "make nios2-generic_config";
For an unknown reason it might require you to run this command again "make nios2-generic_config";
Finally, run "make".

Go to my_first_linux/;
Download the kernel with "wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.6.3.tar.xz";
Extract the file as a directory named "linux";
Go to my_first_linux/linux/ and run "make clean";
Then, run "make 3c120_defconfig";
And finally, "make vmImage" (deu pau!!!!)
