This ticket involves improvements to the IMFS bytes per block behavior. These changes will also need to be reflected in user facing documentation.

  • Currently, the behavior when presented when an invalid configuration value for bytes per block is to silently use the default. It is likely preferable to have a fatal error.
  • Allow for larger block sizes. When implemented, a block size of 512 which resulted in a maximum file size of 1GB was near unimaginable for an embedded system. Allowing for a maximum of at least 1K and possibly 2K seems reasonable now. Note that adding new block size options requires calculating the corresponding maximum file sizes and updating imfs.h and user facing documentation.
