Overview
Module which wraps Flash File System into RAM memory
Discussion
Audio Weaver module which constructs Flash File System instance from the address in RAM, which is used as input e.g. to wave player supporting FFS. This module accepts file system start address on input pin, constructs file system structure instance and send it through the output pin. This module supports additional argument through which user can specify Audio Weaver Flash File System (.bin) file name to simulate functionality on Native-PC target.
...
Similarly the module outputs a 64-bit address on fsInstance output pin.
