As a prerequisite the hdl must be built and referenced when creating a custom version of uboot.

1. Build with provided Virtual Machine
2. Build with user Linux Host

1. Open an embedded command shell from the root directory

    $ ./intelFPGA/18.0/embedded/embedded_command_shell.sh  
   

2. Launch bsp-editor

    $ bsp-editor 
   

3. Create a new BSP

    File --> New HPS BSP  
   

4. Reference the Preloader settings directory

    Copy the hps_isw_handoff folder from the Windows PC where the hdl project was compiled to the VM.
   
    Navigate to the hdl project's hps_isw_handoff/system_bd_sys_hps sub directory. Select "Open", then select "OK".
   

5. Generate the Preloader

    Select "Generate" to create the Preloader project. Select "Exit" to close bsp-editor.
   

6. Build Preloader

    $ cd <where bsp-editor was invoked from>/software/spl_bsp
    $ make  
   

7. preloader-mkpimage.bin is located in the spl_bsp directory

8. Build uboot

    $ cd <where bsp-editor was invoked from>/software/spl_bsp
    $ make uboot
   

9. u-boot.img is located in the spl_bsp/uboot-socfpga directory

1. Download the Intel SoC FPGA Embedded Development Suite

2. Follow the download and install instructions

1. Open an embedded command shell

    $ ./intelFPGA/18.0/embedded/embedded_command_shell.sh  
   

2. Launch bsp-editor

    $ bsp-editor 
   

3. Create a new BSP

    File --> New HPS BSP  
   

4. Reference the Preloader settings directory

    Navigate to the hdl project's hps_isw_handoff/system_bd_sys_hps sub directory. Select "Open", then select "OK".
   

5. Generate the Preloader

    Select "Generate" to create the Preloader project. Select "Exit" to close bsp-editor.
   

6. Build Preloader

    $ cd <where bsp-editor was invoked from>/software/spl_bsp
    $ make  
   

7. preloader-mkpimage.bin is located in the spl_bsp directory

8. Build uboot

    $ cd <where bsp-editor was invoked from>/software/spl_bsp/
    $ make uboot
   

9. u-boot.img is located in the spl_bsp/uboot-socfpga directory
