I'm trying to create my own Quartus project for a Teraisc DE1-SoC board, and I'm stuck generating the bootloader. My end goal is to create a new SD card image that can boot the board with my own design in the FPGA part of the Cyclone V.In order to generate the .dts and .dtb files, I need soc_system_board_info.xml and hps_clock_info.xml. I have download versions that are supposed to match the reference design for the DE1-SoC. However, I do not know how these were created, and they won't match my new Qsys project. (The reference design uses IP some cores I don't have have a license for and don't need. I'm using some, but not all, of the HPS peripherals from the reference board.) How do I regenerate these files so that they match my project?
Hi,After compiling your kernel, check this directory: /arch/arm/boot/dts copy these three files: - skeleton.dtsi - socfpga.dtsi - socfpga_cyclone5.dts Now from the Embedded Command Shell, compile these files into a single .dtb file: dtc -I dts -O dtb -o socfpga.dtb socfpga_cyclone5.dts Copy the generated socfpga.dtb to your SD card and you should be able to boot kernel. I tried this with kernel version 3.10-ltsi, and I think all kernel versions come with .dts files. https://github.com/altera-opensource/linux-socfpga You can edit the socfpga_cyclone5.dts file and add the entries you need and then compile it again. Note: you can use the sopc2dts.exe with your .sopcinfo (you get the dts file) to get the dts entries of your FPGA module.
