  2. Space allocation (file system)
    Configure the space and partition used for crash data storage in the flash_map excel table. To save directly as files, configure SIZE/partition/subdirectory as needed (for reference only; the flash_map excel table is currently supported only by solution projects). You can also create your own file storage.
