# Flattened Device Tree (FDT) Parser

This tool uses our internal FDT (fdt.c) parsing code to dump the device tree. There is also a `-t` option that tests making several updates to the device tree.

## Building fdt-parser

From root: `make fdt-parser`
OR
From `tools/fdt-parser` use `make clean && make`

## Example Output

```sh
% ./tools/fdt-parser/fdt-parser ./tools/fdt-parser/nxp_t1024.dtb
