Reliance Edge Release Notes

This file contains a list of updates made to Reliance Edge over the course of recent releases and a list of known issues.

Release History and Changes

Reliance Edge v2.0, January 2017

  • Added support for Linux as a host environment
    • All "host" projects may now be built in either Windows or Linux using the make command. The formatter and image builder are built, and the checker and image copier are also built in the commercial kit.
    • An additional host tool has been added for Linux only: redfuse. It is a File System in User Space (FUSE) implementation, allowing a Reliance Edge volume to be mounted directly on Linux for easy access. It is built from the host project folder using the command make redfuse.
    • The OS-specific API test (commercial kit only) is now ported to run on Linux for the purpose of verifying the FUSE implementation.
  • Fixed a bug that could leave a directory in an invalid state after removing files. For example, an affected directory might report a non-zero length even after all files had been deleted.
  • Fixed a bug that would leave the driver in a bad state if a mount operation failed due to missing or corrupt metaroot blocks.

Reliance Edge v1.1 (Beta), November 2016

  • Added support for a discard (trim) interface in the commercial kit. While discards are not integral to the behavior of the filesystem, they allow certain types of Flash drivers and media to perform at optimal speed and efficiency. The commercial version of Reliance Edge now allows the user to implement this interface for compatible storage media.
    • This change added new fields to the configuration files redconf.h and redconf.c. The configuration utility has been updated to version 1.1 and existing configuration files must be updated using the updated utility.
  • The configuration utility now has keyboard shortcuts for opening and saving the configuration.
  • The configuration utility now adds version macros to easily identify when an outdated configuration file is used with Reliance Edge or vice versa.

Reliance Edge v1.0.4, July 2016

  • Added ARM mbed and ARM mbed OS support in the commercial kit, with an example projects for ARM mbed OS on the NXP FRDM-K64F board.
  • Some minor deficiencies in the POSIX-like API test suite have been addressed.

Reliance Edge v1.0.3, June 2016

  • Added support for static memory allocation configuration in FreeRTOS version 9. No common code changes.

Reliance Edge v1.0.2, February 2016

Common Code Changes

  • A new per-volume configuration option has been added: users can specify a number of times to retry a block device read, write or flush operation before returning a failure. The configuration tool has been updated to version 1.0.2 with this change.
    • This added a new field to the volume configuration in redconf.c: existing redconf.c files from v1.0.1 and earlier must be updated to work with v1.0.2. Open redconf.h and redconf.c with the configuration tool, enable "Retry block device I/O on failure" for any volumes if desired, and save the redconf files.

FreeRTOS Port Changes

  • Added support for the STM32 HAL SD card driver in the FreeRTOS block device interface. Two boards are supported out-of-the-box: the STM324xG-EVAL and the STM32F746NG-Discovery. A sample project is included for the STM324xG-EVAL.

MQX Port Changes

  • Fixed a bug which prevented Reliance Edge from compiling if the File System Essentials API was selected in the configuration.
  • Fixed a bug which would have returned an uninitialized value from RedOsBDevFlush() for block devices that support flushing.

Reliance Edge v1.0.1, October 2015

  • Added MQX RTOS support in the commercial kit, with example projects for the Kinetis Design Studio.
  • Bug fix in the F_DRIVER implementation of the FreeRTOS block device service.

Reliance Edge v1.0, July 2015

Common Code Changes

  • First release of commercial kit and MISRA C:2012 Design Assurance Package. The commercial kit includes many new tools and tests which were not previously available.
  • Overhauled parsing of command-line parameters to be consistent for all tools and tests. Command-line tools now use Unix-style short and long options (such as -H and --help) instead of DOS-style switches (such as /?).
  • Renamed all os/*/include/ostypes.h headers to os/*/include/redostypes.h, so that all headers use the product prefix. If you created a port using v0.9, this header needs to be renamed and its header guard (#ifndef OSTYPES_H etc.) should also be updated.
  • Add a new header for OS-specific MISRA C:2012 deviation macros, located at os/*/include/redosdeviations.h. If you created a port using v0.9, copy the template from os/stub/include/redosdeviations.h into the include directory.
  • Eliminated support for sector sizes less than 256. If using a smaller sector size (say for a RAM disk), this must now be emulated in the implementation of the block device OS service.
  • Added RedFseFormat() as an optional FSE API, allowing FSE applications to format the volume at run-time.
    • This added a new macro to redconf.h: existing redconf.h files from v0.9 must be updated to work with v1.0. Open redconf.h with the configuration tool, ignore the warning about the missing macro, and save it.
  • Internal restructuring has renamed the macros for the string and memory functions used in redconf.h. An existing redconf.h file from v0.9 will need to be updated; for a file containing the old names, the new config tool will default to using the (slow) Reliance Edge string/memory functions; to use the C library or custom versions, this will need to be selected in the configuration utility.
  • Fix a bug which would result in an error when attempting to create a name with one or more trailing path separators (such as red_mkdir("/foo/bar/")).
  • Fix a bug where an open handle for an inode on one volume would prevent the same inode number from being deleted on a different volume.

FreeRTOS Port Changes

  • The implementation of the timestamp OS service no longer requires that configUSE_TIMERS be set to 1.

Reliance Edge v0.9 (Beta), April 2015

First public release.

Known Issues

Visual Studio 2005

The Reliance Edge Win32 port (used for the host tools and the Win32 test project) cannot be compiled by Visual Studio 2005. This is not going to be fixed since VS2005 is an old toolset. Newer versions of Visual Studio, starting with Visual Studio 2008, work just fine.
