Category: SoCs
Tools: SoC EDS
Device: Arria® V, Cyclone® V


To create a device tree for your custom board, run the following commands from the SoC EDS Embedded Command Shell:

<Procedure>

1. Create any working directory. (e.g. C:\Work\cv_soc_devkit_ghrd)
   $ mkdir "C:\Work\cv_soc_devkit_ghrd"
2. Change to the working directory you created.
   $ cd "C:\Work\cv_soc_devkit_ghrd"
3. Copy the soc_system.sopcinfo file generated by the design for your custom board to your working directory.
4. Copy the following two XML files included in SoC EDS to your working directory.
   $ cp "C:\altera\15.1\embedded\examples\hardware\cv_soc_devkit_ghrd\hps_common_board_info.xml"
   $ cp "C:\altera\15.1\embedded\examples\hardware\cv_soc_devkit_ghrd\soc_system_board_info.xml"
5. Refer to https://rocketboards.org/foswiki/view/Documentation/GSRDV151DeviceTreeGenerator and rewrite the copied XML file with a text editor for your custom board.
6. Running the sopc2dts command below generates the socfpga.dtb file.
   $ sopc2dts --input soc_system.sopcinfo\
   --output socfpga.dtb\
   --type dtb\
   --board soc_system_board_info.xml\
   --board hps_common_board_info.xml\
   --bridge-removal all\
   --clocks

<Note>

1. Here is an example when SoC EDS is installed in C:\altera\15.1.
2. If you are targeting the Arria V SoC development kit, replace cv_soc_devkit_ghrd with av_soc_devkit_ghrd in the command above.
