PXS Software - RedBoot Loader

When turned on, the PXS executes a POST (Poer-On Self-Test) and then loads and executes a version of the RedBoot bootstrap environment.

If no RedBoot commands are issued during a configurable time-out interval (default 15 secs), it loads and executes the LayGO® server application.

This graphic shows RedBoot's main components. (Hold the mouse over the balloons to see the explanations.)

The 4 MB Flash Memory organized as a non-hierarchical disk contains 64 x 64 KB sectors. The first three sectors are protected and contain RedBoot and its loader, the last two sectors contain the Flash Image System (FIS) directory and configuration data. RedBoot includes basic terminal, TCP/IP, and TFTP support.
