Detailed Description

The eXecute In-Place File System.

xipfs is a file system designed to streamline post-issuance software deployment.

xipfs allows direct execution of programs from flash memory, eliminating the need for prior copying to RAM.

This approach conserves memory space and accelerates boot times, as the microcontroller can run code directly from storage memory without preloading into RAM.

The xipfs structure is based on a linked list, where each file occupies at least one flash memory page.

To prevent fragmentation, when a file is deleted, subsequent files are shifted to fill the vacant space.

xipfs is compatible with all microcontrollers featuring addressable flash memory and most operating systems, provided they implement the necessary functions to interact with the flash controller.

To have a viable executable file within XiPFS, please follow these steps :

create a file with executable flag.
Fill it with actual compiled code in an appropriate file format, here XiPFS-Format. This is where the actual startup sequence and relocation happen.
Call execute on it with appropriate args at least the executable filename should be passed along.
