What is Firmware Inspector?
Firmware Inspector parses and converts between the common firmware file formats used in embedded systems development. Intel HEX and Motorola S-Record are text-based formats that encode binary data with memory addresses and checksums. This tool decodes these formats, validates their integrity, and lets you convert between them or extract raw binary data.
Embedded developers frequently work with firmware images when programming microcontrollers, debugging bootloaders, or verifying build outputs. Manually reading HEX files or correlating memory addresses is tedious and error-prone. DevKit’s Firmware Inspector provides a structured view of every record, including its address, data length, type, and checksum status.
How to Use Firmware Inspector
Paste the contents of an Intel HEX or S-Record file into the input editor, or import a binary file from your device. The tool auto-detects the format and parses each record. A summary view shows the memory address ranges covered, total data size, and any checksum errors.
The hex dump view presents the binary data in a traditional format with address offsets, hexadecimal byte values, and an ASCII representation sidebar. You can navigate to specific addresses or search for byte patterns.
Common Use Cases
- Firmware verification: Validate that a compiled HEX or S-Record file has correct checksums and expected memory layout before flashing to a device.
- Format conversion: Convert Intel HEX to S-Record or vice versa when switching between programming tools or target platforms.
- Binary extraction: Extract raw binary data from HEX files for direct memory comparison or for tools that require flat binary input.
- Bootloader debugging: Inspect firmware image headers, vector tables, and metadata regions to diagnose boot failures.
- Production testing: Verify firmware file integrity on the go during factory programming or field updates of embedded devices.
