Crate fdt_raw 

Raw FDT parser without high-level abstractions.

This crate provides a very low-level parser for Flattened Device Tree (FDT) files. It is designed to be a minimal dependency that only handles the binary format of device tree blobs without providing any node or property abstractions.

Features

• #![no_std] compatible
• Zero-copy parsing where possible
• Direct access to the FDT structure blocks
• Minimal dependencies

Example

use fdt_raw::{Fdt, Header};

// Read FDT data from file or memory
let data = std::fs::read("path/to/device.dtb")?;

// Parse the header
let header = Header::from_bytes(&data)?;

println!("FDT version: {}", header.version);
println!("Total size: {} bytes", header.totalsize);

// Create the FDT parser
let fdt = Fdt::from_bytes(&data)?;

// Iterate over memory reservation entries
for rsv in fdt.memory_reservations() {
    println!("Reserved: {:?} - {:?} bytes", rsv.address, rsv.size);
}
