Dynamic Configuration with User Specified dtsi/dtbo Flow for Zynq/ZynqMP/Versal - 2023.2 English - UG1144

PetaLinux Tools Documentation: Reference Guide (UG1144)

Document ID

UG1144

Release Date

2023-10-18

Version

2023.2 English

This section provides information on the mechanism and infrastructure required to work with custom IPs that have readily (hand-stitched) available dtsi files instead of relying on the DTG to generate them when the FPGA manager is enabled. This generates/packs the dtbo and bin/pdi files into the rootfs /lib/firmware/xilinx directory.

Prerequisites

dtsi and its corresponding pdi/bit.bin or
dtbo and its corresponding pdi/bit.bin files

Build Steps

Source the PetaLinux tool.

source /opt/petalinux/petalinux-v<petalinuxversion>/settings.sh

Create a Versal template project or BSP project

petalinux-create -t project -n zynqmp-dfx --template versal
 petalinux-create -t project -s <bsp path> -n zynqmp

Go to the project
```
cd zynqmp-dfx
```

Configure the project with static.xsa/base.xsa

petalinux-config --get-hw-description <base.xsa/static.xsa>

Enable FPGA manager using the following command:
```
 petalinux-config -> FPGA MANAGER
```
Note: The PetaLinux FPGA manager configuration performs the following:
- fpga-overlay Machine features
- Enables the required kernel configs to load the fpgamanager driver

Create the FPGA manager template

petalinux-create -t apps --template dfx_user_dts -n can-interface --srcuri "can.dtsi can.bit.bin" --enable

petalinux-create -t apps --template dfx_user_dts -n can-interface --srcuri "can.dtbo can.bit.bin" --enable

petalinux-create -t apps --template dfx_user_dts -n can-interface --srcuri "can.dtsi can.pdi" --enable

petalinux-create -t apps --template dfx_user_dts -n can-interface --srcuri "can.dtbo can.pdi" --enable

petalinux-create -t apps -template dfx_user_dts -n usrapp -scruri "user.dts user1.dtsi user2.dtsi system.pdi" -enable

Build the application.
If you want to build as part of rootfs
```
 petalinux-build 
```
Or
```
petalinux-build -c rootfs
```
If you want to build only the application.
```
petalinux-build -c can interface
```

Boot Steps

Up the target with previously built images using any of the boot methods in the documentation. Once the target is up, run the following commands.

fpgautil -o /lib/firmware/can interface/pl.dtbo -b /lib/firmware/xilinx/can interface/design_1_wrapper.bit.bin
