debugnet is a vita small library to debug your homebrew code over udp. It is the same method that i use to debug PlayStation 3 code, so i can use the same host tools for PlayStation Vita and PlayStation 3 to do it.

1. Compile and install library and include file

cd libdebugnet
make
make install

or

mkdir build
cd build
cmake ..
make 
make install

2. Compile sample

cd sample
edit main.c and change your server ip and port to listen udp messages from PlayStation Vita
make

3. Open a terminal and execute (change port if you don't use 18194). It can be in osx, linux or if you have socat like tool on windows

socat udp-recv:18194 stdout 

4. Install debugnetsample.vpk in your vita an run it

You will see in socat terminal window output from your PlayStation Vita:

debugnet initialized
