Overview
The GR-LEON4-ITX board's SPI boot PROM has been programmed with boot loader that

kernel then mounts its root file system, containing initialization scripts and software, from a
USB Flash stick. The Linux console is available both over the DVI video interface and over
the serial terminal.

Therefore the USB stick must be attached to the board. As previously stated, the Linux
console is available both over the video interface and over the serial terminal. As the board
