| Error Message | Likely Cause | Solution | |---------------|--------------|----------| | “File size mismatch” | sp5001.bin is for a different flash chip (256KB vs 512KB) | Re-download correct version using exact device model number | | “Invalid checksum” | Corrupted download or modified file | Compare SHA-1 hash with vendor’s reference | | “Device not responding” | Wrong boot mode or poor connection | Retry after power-cycling; check serial/UART wiring | | “No signature found” | sp5001.bin is not meant for this bootloader version | Extract vendor-specific header using a script (see below) |
Scenario: Successfully processing a valid binary file Given a file named "sp5001.bin" exists in the staging directory And the file has a size of 2048 bytes And the file header contains the magic bytes "SPX1" When I initiate the binary ingestion process Then the system should read the binary payload And the system should validate the CRC-32 checksum And the system should parse 500 index records And the system should persist the records to the "index_constituents" table And the file "sp5001.bin" should be archived to "/data/processed" And the log should show "Ingestion Complete: 500 records" sp5001.bin
