obu-firmware builds against vanetza-idf from microbu-esp32c5/external, but that tree was gitignored, so a clone of this repository could not build the firmware it ships. It is now committed here as ordinary files in its own folder, microbu-esp32c5/: the colleague's commit cf4b99f plus the V2X2MAP bridge's signature verification (--trust) used on the bench. Nothing is fetched from or pushed to the colleague's repository; this repository and its remotes carry everything. The folder's own .gitignore keeps build output, downloaded components and private key material out, as it did there; the committed file set is identical to that repository's tracked files. The ESP32-C5 is still flashed from obu-firmware/, which only takes vanetza-idf from microbu-esp32c5/, so the two stay separate folders. FLASHING.md says how to take a newer version of the colleague's tree (copy it over the folder, rebuild, test, commit).

Title: Building for generic ARM64 device

# Building Vanetza for generic ARM64 device
|
|
|
|
This document describes building Vanetza for arm64 architecture.
|
|
Steps for building Vanetza for arm64 are very similar to build for Cohda MK5 devices (you can see steps in the [building for Cohda MK5 document](cohda-sdk-build.md)).
|
|
|
|
## Cross-compiler
|
|
|
|
You should have GNU C/C++ cross-compiler for the arm64 architecture installed. For Debian-based distros, this can be installed by command `sudo apt install g++-aarch64-linux-gnu`.
|
|
|
|
## Vanetza build dependencies
|
|
|
|
Please see [this document](cross-compile-dependencies.md) about cross-compiling Vanetza's dependencies.
|
|
|
|
## Compile Vanetza
|
|
|
|
We assume you have copy of the Vanetza repository in your home directory at `$HOME`.
|
|
Create a build directory and tell CMake to use the cross-compiler installed on your machine and to look up additional dependencies in `vanetza-deps`:
|
|
|
|
:::shell
|
|
mkdir vanetza/vanetza-build
|
|
cd vanetza/vanetza-build
|
|
cmake .. \
|
|
-DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-ARM64.cmake \
|
|
-DCMAKE_FIND_ROOT_PATH=$HOME/vanetza-deps \
|
|
-DCMAKE_INSTALL_RPATH=\$ORIGIN/../lib \
|
|
-DCMAKE_INSTALL_PREFIX=$HOME/vanetza-dist \
|
|
-DBUILD_SOCKTAP=ON
|
|
make
|
|
|
|
This builds the Vanetza libraries and *socktap* example as well. When you do `make install`, binaries are copied to `$HOME/vanetza-dist`. You can copy the binary with libraries to the device now.
