This section describes an exemplary boot process, which means that the output depends on the specific system and has not to be the same, with its stage-specific outputs as mentioned in page "Board bring-up overview for TEI0022". The first section describes an overview with the information at which point which boot stage is started. The second section shows an exemplary excerpt from a boot process.
