Abstract: A target system is dynamically configured to boot from a network connection upon power-up. A portable data loader connected to the target system may receive communications from the target system that a connection has been established. In response, a copy of a target-specific software data loader (SWDL) application may be transmitted from the portable data loader to the target system. The copy of the SWDL application may be stored in volatile memory on the target system and may be executed to support at least one maintenance operation. A user may invoke a maintenance operation by entering a command into the portable data loader. By isolating the data loader application from the operational software stored on the target system, the disclosed methods and apparatus may allow for reduced development and software certification costs for implementing maintenance operations on an embedded system.
