Setting-Up the File System
The RL-Flash file system can be used standalone or in conjunction with RTX.
The file system library functions are re-entrant and thread safe. Therefore, with
RTX, any task can access the file system. Note that, if the code is build with the
MDK-ARM, MicroLIB is not supporting the
system, and so you must use the default ARM Compiler libraries.
The RL-Flash file system can use on-chip or external SRAM. If an external
SRAM is used, provide the initializing code to configure the external bus of the
microcontroller. In the examples below, we configure the file system to use the
internal RAM of a typical microcontroller.
The minimal configuration of the RL-FlashFS file
system consists of its library and a configuration file.
