Reliance Edge v2.1, October 2017

Common Code Changes

• Added optional support for current working directories, relative paths, and dot and dot-dot handling. This includes the new red_chdir() and red_getcwd() APIs.
• A volume path prefix, by itself, is now a valid reference to the root directory on that volume. Assuming the path prefix is "VOL0:" and the path separator character is '/', previously red_opendir("VOL0:/") would succeed and red_opendir("VOL0:") would fail. Now both will succeed. This results in more intuitive behavior when the volume path prefix is changed to look like a directory, such as "/sdcard"; red_opendir("/sdcard") and red_chdir("/sdcard") intuitively look like they should work, and now they do.
• Updated the imgcopy utility to open files in binary mode. When used on Windows, this fixes a problem where Windows attempted to perform newline conversion in binary files, corrupting the file data.
• Fixed a bug in the POSIX-like API Test Suite which caused it to fail when run on a volume other than volume zero. Fixed another bug which caused it to fail when the volume name was unusually long.
• Added an option to FSIOTest to control flush frequency for the sequential write and sequential rewrite tests. Default behavior is unchanged.

INTEGRITY Port Changes

• Added support for the INTEGRITY RTOS in the commercial kit. Reliance Edge integrates into the INTEGRITY file system layer so that system calls like open() or read() work with Reliance Edge; there is no need to update an application to use Reliance Edge's POSIX-like API.
• Example projects for the BeagleBone Black are provided.
• For the time being, the osbdev.c implementation is only known to work with the SD card driver supplied with the BeagleBone Black BSP. It is known not to work with the IDE driver used on x86 PCs. Other storage drivers have not been tested.
• See the "INTEGRITY Integration" chapter of the Developer's Guide for further details on INTEGRITY support. Please read this chapter before using Reliance Edge on INTEGRITY.

FreeRTOS Port Changes

• Moved the several example implementations in osbdev.c into header files.
• Added a "stub" example, which is now the default implementation for FreeRTOS, and which deliberately does not compile. This is to make it obvious that FreeRTOS users need to make modifications to osbdev.c for their environment.
• Added support for using Datalight FlashFX Tera as a block device. This support only exists in the commercial kit.
• The Atmel Studio projects for the SAM4E-EK and SAM4S Xplained Pro boards are no longer included in the open source kit; they are still available in the commercial kit.
