ROFSBUILD Obey File Structure

A ROFS image is used to store code that is not part of the Core +OS section. The File Server uses ROFS (the Read-Only File System) +to access this, and ROFS uses a Media Driver to read the data from +the NAND Flash device and to load this into RAM for access or execution. +The Composite File System combines this media area with the Core OS +media area and presents the two as a single read-only drive Z:.

A ROFS image contain the following main sections:

a CoreImage section that specifies the existing core image to be used as the +base for generating the extension image.
an ExtensionRomSection that defines the ROM image that extends the core image.

The structure is defined as:

+ObeyFile : CoreImageStatement [ ExtensionRomSection ] +CoreImage : coreimage = <CoreImageFileName> +ExtensionRomSection : ObeyStatementList +ObeyStatementList : ObeyStatement | ObeyStatement ObeyStatementList +ObeyStatement : RomStatement | FileStatement +
