FreeRTOS+FAT is still in the lab
FreeRTOS+FAT is already in use in commercial products and we encourage you to try it yourself. Be aware however that FreeRTOS+FAT was acquired by Real Time Engineers Ltd., and is still being documented and updated to ensure it meets our strict quality standards. Please use the forum for support, or contact us directly if you have a specific business interest.

FreeRTOS+FAT
DOS Compatible Embedded FAT File System

FreeRTOS+FAT is an open source, thread aware and scalable FAT12/FAT16/FAT32 DOS/Windows compatible embedded FAT file system which was recently acquired by Real Time Engineers ltd. for use with and without the RTOS.

FreeRTOS+FAT is already used in commercial products, and is the file system used in the FTP and HTTP server examples that are documented on the FreeRTOS+TCP pages.

The standard C library style API includes a thread local errno value, and the lower level native API provides a rich set of detailed error codes.

We are currently working hard on improving the embedded file system's documentation, adding additional scalability options, and updating the source code to ensure it conforms with our strict coding standards. We encourage you to download FreeRTOS+FAT to try the embedded FAT file system for yourself while we continue this work.
