# Early Boot Utils User Guide
This repository contains the following tools for help with "early boot - late attach".
1. `dump_rsc_table` - prints the resource table of an ELF binary
2. `check_late_props` - checks whether late attach properties are set on the device tree correctly.
3. `print_macros_for_mlo` - prints the macros that need to be defined in MLO to correspond to the device tree being used.
## Building the tools
The tools in this repository are built with [CMake](https://cmake.org/).
1. Install dependencies.
~~~{.bash}
$ sudo apt-get install cmake libfdt-dev
~~~
2. Clone the git repository.
~~~{.bash}
$ git clone git://git.ti.com/glsdk/earlyboot-utils.git
~~~
3. Build `earlyboot-utils` and install them to the desired location.
~~~{.bash}
$ cd earlyboot-utils
$ mkdir -p build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=~/.local/ ..
$ make install
~~~
This will install the tools to `~/.local/bin`. You can change the
location according to your preference.
When you run the tools below, please make sure to include their
location in the `PATH`
~~~{.bash}
$ export PATH=$PATH:~/.local/bin
$ dump_rsc_table dra7-ipu2-fw.xem4.ipumm-fw
~~~
or invoke them by their absolute path.
~~~{.bash}
$ ~/.local/bin/dump_rsc_table dra7-ipu2-fw.xem4.ipumm-fw
~~~
The tools can also be cross compiled for the target by defining a
toolchain file. Please see
<http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_Application_Notes#CMake>
