what is dtbo

Full Answer

What does dtbo stand for?

.dtbo - Linux Device Tree Overlay. The DTBO development files are related to Device Tree Compiler. DTBO file is a Linux Device Tree Overlay. Device Tree Compiler (dtc) - converts between the human editable device tree source "dts" format and the compact device tree blob "dtb" representation usable by the Linux kernel.

How to open dtbo device tree blob overlay file?

a dtbo device tree blob overlay file is a special file format by Acme Systems and should only be edited and saved with the appropriate software. Associate the DTBO file extension with the correct application. On , right-click on any DTBO file and then click "Open with" > "Choose another app".

How to open dtbo files?

What table structure should I use for my DTB/dtbo?

If your DTB/DTBO is in a unique partition, e.g. dtb and dtbo partition, use the following table structure and header format: Figure 1. Example dtb / dtbo partition layout (for AVB signature, see Security ). The dt_table_header is only for the dtb / dtbo partition; you CANNOT append this format after the end of image.gz.

Can't open a .dtbo file?

When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:

What does passing the @ flat to dtc do?

Passing the -@ flat to dtc will make it retain information about labels when generating a dtb file, which will allow Linux to figure out at runtime what device tree node a label was referring to. You can read more about this mechanism in the Raspberry Pi documentation page linked at the bottom of the article. However, as a person trying to use device tree overlays, simply passing the -@ flag to dtc when compiling the base device tree will allow labels to work.

What is a device tree?

The device tree contains information about both the PS and PL. Petalinux uses the BSP and Vivado export files to generate a device tree for the PS and PL, then combines them into a single system.dts file which you can find in the images/linux folder after creating a build. Additionally, hardware connected to the FPGA will have its own device tree structure that you must specify in .dtsi files, and Petalinux will integrate these into the system.dtb file. The system.dtb file gets packed into image.ub (which itself might get packed into BOOT.BIN). During boot, U-Boot copies the device tree to a specific location in memory, and Linux reads the device tree from memory when booting.

Can you use dtsi in Petalinux 2019?

Notably, if you are using Petalinux 2019.1, and you have PL dtsi files which you include in the build, and you do not want to use FPGA Manager, then by using just the config flags there is no way to have Petalinux pass the -@ flag to dtc. However, there are a few workarounds for this issue which can allow you to use target labels with 2019.1.
