Ug linux fabric config s10sx soc
Introduction¶
When using HPS Boot First method, the FPGA device is first configured with a small Phase 1 bitstream, which configures the periphery, and brings up HPS. Then, at a later time, HPS configures the FPGA fabric using a larger Phase 2 bitstream.
The HPS can configure the fabric either from U-Boot or Linux. The Golden System Reference Design (GSRD) configures the fabric from U-Boot. The examples in this page demonstrate how to configure the FPGA fabric from Linux, using device tree overlays.
Two different examples are provided:
- Example building components separately
- based on the Building Bootloader for Stratix10 example.
- Manages overlays directly.
- Example building everything with Yocto
- Based on the Stratix® 10 SoC H-Tile GSRD.
- Manages overlays with the dtbt utility
Prerequisites¶
You will need the following items:
- Stratix® 10 SX SoC Development Kit, production version, H-Tile (ordering code DK-SOC-1SSX-H-D):
- NAND/eMMC HPS Daughtercard
- SDM QSPI Bootcard with MT25QU02G flash device
- Linux host PC (Ubuntu 22.04LTS was used for developing this project, but other versions may work too)
- Internet access (for downloading files attached to this page, and cloning git trees from github)
- TFTP server running on host computer (or other accessible computer on the local network)
- Altera® Quartus® Prime Pro Edition Version 24.2
Refer to board documentation for more details about the development kit.
Example Building Components Separately¶
This example is build on top of the Building Bootloader for Stratix10 example, with the modification that the fabric is not configured from U-Boot anymore, but from Linux, with a device tree overlay.
The device tree overlay and the Phase 2 configuration bitstream core.rbf are stored in the Linux rootfs folder /lib/firmware, where the Linux overlay framework expects them to be by default.
Full instructions for building and running the example are provided.

Explanation:
Fragment@0: Node Name of the Overlay.target-path: This refers to base_fpga_region located in arch/arm64/boot/dts/intel/socfpga_agilex.dtsi. This will invoke the following driver: drivers/fpga/of-fpga-region.c- Fragment@0
#address-cells/#size-cells: This specifies the number of cells (32-bit size) to be used for the child's address map. For overlays, we need to set this value to avoid "default_addr_size" errors. - overlay
#address-cells/#size-cells: These fields should match those in arch/arm64/boot/dts/intel/socfpga_agilex.dtsi. Ranges: According to the device tree standard, this allows mapping child addresses to parent addresses. In this case:- The first number
<0x0 0x0 0xF9000000 0x0 0x00200000>represents the child's address. - The second pair
<0x0 0x0 0xF9000000 0x0 0x00200000>represents the parent's address. - The third pair
<0x0 0x0 0xF9000000 0x0 0x00200000>specifies the memory region's size.
- The first number
firmware-name = "overlay.rbf": This should contain the fabric's file name.sysid_qsys_0: sysid@0: This specifies the device name as well as its alias.reg = <0x0 0x0 0x0 0x00000010>: This refers to the addresses specified in the parent range field.<0x0 0x0 0x0 0x00000010>: This represents the child's address.<0x0 0x0 0x0 0x00000010>: This is the size of the memory region.

6. List the applied overlays:
root@stratix10:~# dtbt -l
1 fabric_config_overlay.dtbo applied /sys/kernel/config/device-tree/overlays/1-fabric_config_overlay.dtbo
7. Locate the sysid in the sysfs:
root@stratix10:~# find / -name sysid
/sys/devices/platform/soc/soc:base_fpga_region/f9000000.sysid/sysid
8. Display the sysid id information:
root@stratix10:~# cat /sys/devices/platform/soc/soc:base_fpga_region/f9000000.sysid/sysid/id | xargs printf "0x%08x\n"
0xacd5cafe
9. Remove the overlay:
root@stratix10:~# dtbt -r fabric_config_overlay.dtbo -p /boot/devicetree
Set dtbo search path to /boot/devicetree
Removing dtbo: 1-fabric_config_overlay.dtbo
10. Confirm that the overlay was removed:
