This is a more advanced guide of my Designing of custom rsyoto versions to show how to use the build system with custom Yocto Project Linux distributions to automate the entire bootflow for Intel Cyclone V and Intel Arria 10 SX SoC-FPGA. The Python scripts work with any Intel Cyclone V and Intel Arria 10 SoC-FPGA board with booting via SD-Card.
Use your Intel Quartus Prime FPGA project to create your own rsyocto with your FPGA Configuration

This is a more advanced guide of my Designing of custom rsyoto versions to show to how use the build system with custom OpenEmbbeded Yocto Project Linux Distributions to automate the entire bootflow for Intel Cyclone V- and Intel Arria 10 SX SoC-FPGA.
-
Install all required tools, like Intel SoC-EDS on a Linux Computer
- For installing and setting up of your build computer please follow the instructions of the Designing of custom rsyoto versions guide
-
Download and unzip the SD-Card folder
- Download the "rsyocto_SDxx-Folder" from the "releases Part" of this Github repository
- Unzip the folder
-
Copy this folder into your Intel Quartus Prime FPGA project folder
-
Change the files of the SD-Card folder for your requirements
- To allow to generate special Linux Distributions change the SD-Card folder as described in the Designing of custom rsyoto versions guide
-
Run the rsyocto build script with your Yocto-Project Linux files
- The "makersyoctoSDImage.py" Python script allows some specific attributes:
vm@yoctoBuntoX:~/Desktop/DE10NANOrsyocto/socfpgaPlatformGenerator$ python3 makersyoctoSDImage.py -h ############################################################################## # # # ######## ###### ## ## ####### ###### ######## ####### # # ## ## ## ## ## ## ## ## ## ## ## ## ## # # ## ## ## #### ## ## ## ## ## ## # # ######## ###### ## ## ## ## ## ## ## # # ## ## ## ## ## ## ## ## ## ## # # ## ## ## ## ## ## ## ## ## ## ## ## # # ## ## ###### ## ####### ###### ## ####### # # # # AUTOMATIC SCRIPT FOR BRINGING A CUSTOM RSYOCTO LINUX FLAVOR # # TO A BOOTABLE IMAGE FILE # # # # by Robin Sebastian (https://github.com/robseb) # # Contact: git@robseb.de # # Vers.: 3.11 # # # ############################################################################## usage: makersyoctoSDImage.py [-h] [-y YOCTO_LINUX] [-g DEVICETREE_GEN] optional arguments: -h, --help show this help message and exit -y YOCTO_LINUX, --yocto_linux YOCTO_LINUX Use the Yocto Project zImage,rootfs files ["-y 1"] -g DEVICETREE_GEN, --devicetree_gen DEVICETREE_GEN Use SoC EDS DeviceTree Generator ["-g 1 --> no GUI | 2 --> GUI"]
- Possible arguments of the script:
- "
-y" or "--yocto_linux" enables to use the output files of the Yocto Project (zImage, rootfs and Linux Device Tree) for the build- The script copies these files from the Yocto Project output folder to the SD-Card partitions, instead of the Linux files located inside the SD-Card folder
- "
-g" or "--devicetree_gen" uses the Intel Device Tree generated to automatically generate a Linux Device Tree based on Intel Quartus Prime FPGA Project settings- The Device Tree file will be located inside the SD-Card partition folder and can only be seen as reference because the Intel Device Tree generator is not recommenced by Intel any more
- "
- Start the build script to generate a Linux Distribution with your Yocto-Project files
python3 makersyoctoSDImage.py -y 1
-
Follow the instruction of the Python build script
- The procedure will be identical as shown in the Designing of custom rsyoto versions guide
- Only the following message box will appear to show the available Yocto Project output Linux Distribution files
########################################################################################## # COMPATIBLE YOCTO PROJECT LINUX DISTRIBUTION WAS FOUND # # Use this distribution for the build? # # # #----------------------------------------------------------------------------------------# # No. | Specs of the found Yocto Project Linux Distribution # #----------------------------------------------------------------------------------------# # 1 | Directory: "/home/vm/poky/build/tmp/deploy/images/cyclone5/" # # 2 | Modification Date: Tue Apr 6 16:28:01 2021 # # 3 | rootfs: "core-image-minimal-cyclone5-20210406142211.rootfs.tar.gz # # 4 | zImage: "zImage--5.10+gitAUTOINC+f7700e50b1-r0-cyclone5-20210407093253.bin" # # 5 | Devicetree: "-" # #----------------------------------------------------------------------------------------# # # ########################################################################################## ####################################################################### # Use this distribution for the build? # # # #---------------------------------------------------------------------# # No. | Task # #---------------------------------------------------------------------# # 1 | Yes, use these files for this build # # 2 | No, copy file manually instead # # 3 | Use the existing Linux files inside the Partition folder # #---------------------------------------------------------------------# # Select a item by typing a number (1-3) [q=Abort] # # Please input a number: $
- Type
1to let the script use these files for the build
-
Select the Linux Device Tree for the build
- My meta-intelfpga BSP layer for the OpenEmbedded Yocto Project did not built the Linux Device Tree
- Instead, the build script will ask the user to copy a Linux Device Tree file with a specific name to the Image Partition folder as shown:
################################################################################################################# # Inside the Yocto Project Repo. folder no Linux Devicetree (.dts) was found! # # Use the existing Linux devicetree file inside the partition folder OR # # Copy a Linux devicetree file (.dts) to the partition folder # # # #---------------------------------------------------------------------------------------------------------------# # No. | Name and Location of the required file to copy # #---------------------------------------------------------------------------------------------------------------# # 1 | Directory: "/home/vm/Desktop/DE10NANOrsyocto/socfpgaPlatformGenerator/Image_partitions/Pat_1_vfat" # # 2 | Requiered Name: "socfpga_cyclone5_socdk.dts" # #---------------------------------------------------------------------------------------------------------------# # # #################################################################################################################
- For reference the Intel Device Tree generator can also be used. To do this run this script
python3 makersyoctoSDImage.py -g 1
- The Python script will place this Linux Device Tree file with the name "_reference.dts" to the Board folder
- Copy the file with the shown name to the shown location and continue the script
- The script will generate a bootable Linux Distribution image for the Intel Quartus Prime FPGA project
-
Flash the image to a SD-Card and boot your Intel SoC-FPGA board up
- Done ...
