Overview
This readme is about the OpenAMP rpc_demo demo. The rpc_demo is about one processor uses the UART on the other processor and creates file on the other processor’s filesystem with file operations.
For now, It implements the remote processor running generic(baremetal) application accesses the devices on the Linux.
Compilation
Add cmake option -DWITH_PROXY=ON -DWITH_APPS=ON to build the system reference demonstration applications.
Baremetal Compilation
Here is an example to generate the to generate the rpc_demo application:
cmake -DCMAKE_TOOLCHAIN_FILE=zynqmp_r5_generic -DWITH_APPS=ON -DWITH_PROXY=ON
System Reference Legacy Apps Build Overview
This page details how to setup and build the OpenAMP System Reference legacy apps and test examples found in the examples/legacy_apps directory. These applications were moved from the OpenAMP repository.
Initialization
The first step is to initialize the workspace folder (my-workspace) where
the examples and all Zephyr modules will be cloned. You can do
that by running:
# initialize my-workspace for the example-application (main branch)
west init -m https://github.com/OpenAMP/openamp-system-reference --mf examples/legacy_apps/west.yml --mr main my-workspace
# update modules
cd my-workspace
west update
Build
The following steps are to build legacy apps on a host machine.
export PROJECT_ROOT=$PWD
Build libmetal
cd $PROJECT_ROOT/libmetal
cmake . -Bbuild -DCMAKE_INSTALL_PREFIX=$PROJECT_ROOT/target
make -C build VERBOSE=1 install
Build open_amp
cd $PROJECT_ROOT/open-amp
cmake . -Bbuild -DCMAKE_INCLUDE_PATH=$PROJECT_ROOT/libmetal/build/lib/include/ -DCMAKE_LIBRARY_PATH=$PROJECT_ROOT/libmetal/build/lib/ -DCMAKE_INSTALL_PREFIX=$PROJECT_ROOT/target
make -C build VERBOSE=1 install
Build legacy Apps
cd $PROJECT_ROOT/openamp-system-reference/examples/legacy_apps
cmake -Bbuild \
-DCMAKE_INCLUDE_PATH="$PROJECT_ROOT/libmetal/build/lib/include/;$PROJECT_ROOT/open-amp/build/lib/include/" \
-DCMAKE_LIBRARY_PATH="$PROJECT_ROOT/libmetal/build/lib/;$PROJECT_ROOT/open-amp/build/lib/" \
-DCMAKE_INSTALL_PREFIX=$PROJECT_ROOT/target
make -C build VERBOSE=1 install
If you are perusing the github repository refer to the legacy_apps README.md for compilation information.
Linux Compilation
See README.md to generate the rpc_demod application.
Run the Demo
The demo application will load the remoteproc module, then the proxy rpmsg module, will output message sent from the other processor, send the console input back to the other processor. When the demo application exits, it will unload the kernel modules.
