Amora is a bare-metal kernel targeting the BeagleBone Black board, supporting the ARM Cortex-A8. It is in development.
In order to build Amora, run make. The kernel image kernel.bin will be generated inside the folder obj.
Communication with the BeagleBone Black is done through the UART serial port. You will need a serial cable connected to the board and a serial terminal running at 115,200 8N1.
