How to use Intel HEX Firmware Record Workbench

Validate Intel HEX records, normalize record layout or export a bounded address-span binary. Checks byte counts, checksums, extended segment/linear addresses, a single optional start address, overlapping ranges and the final EOF record.

  1. Provide optional intel hex file, intel hex records.
  2. Choose the supported mode and run the tool. Review its assumptions and any reported errors.
  3. Copy the result or download a separate output; reset to clear the current form.

Good to know

  • 1MiB ASCII,10000 records,2MiB actual payload. Binary output span is capped at2MiB before allocation; gaps use the selected byte.
  • Conflicting/duplicate start-address, overlapping data and cross-64KiB-offset data records are rejected; split boundary-spanning data records first. Type03 CS:IP and type05 EIP records retain their original semantics. No device, firmware integrity, signature or flash operation is performed.
  • Inputs are processed on this device and are not automatically saved or uploaded.

Common questions

Does a valid checksum mean the firmware is safe?

No. Intel HEX checksums detect record corruption; they do not establish authenticity or compatibility with a target device.

Does this change my original input?

No. The tool returns a separate result. Review that output before using it in another application.
