- First, create a new software folder inside the hardware Engineering folder to place the software part; open toolsàNios II 11.0 software Build Tools for Eclipse, need to workspace Launcher (Workspace) path settings, it is important to note that the path does not contain spaces, etc., and then click OK.
?
- New project. Click File--New->? Nios II application and BSP from template, pops up Nios II application and BSP from Template dialog box. Select the corresponding SOPC system first, click the browse button after Sopc information file name, select the soft core file that was previously done by the hardware section, The suffix name is. Sopcinfo, it is important to note that the selected files must correspond, otherwise the system will fail because of a soft and hard mismatch. Here Select the Hello_world.sopcinfo, then the system will automatically read the CPU name, no more settings, the following fill out project name, here to fill in the Lab1_hello_world, Project template (Project Template) using the default. Then click Finish to finish. This will generate two project files in the Project Explorer on the left.
