• vclog - A tool to get VideoCore 'assert' or 'msg' logs with optional -f to wait for new logs to arrive.

Build Instructions

Install the prerequisites with "sudo apt install cmake device-tree-compiler libfdt-dev" - you need at least version 3.10 of cmake. Run the following commands to build and install everything, or see the README files in the subdirectories to just build utilities individually:

• cmake .
• make
• sudo make install
