KITE Reflasher
Released Version 0.2.1A UDS-on-CAN reflashing tool for ECU firmware download and update validation, covering download sequences, Security Access, firmware formats, and trace retention.
Overview
Turn ECU reflashing into a controlled download workflow
KITE Reflasher supports ECU firmware programming, bootloader bring-up, download sequence validation, and pre-delivery update tests. Engineers can configure diagnostic sessions, Security Access, RoutineControl, RequestDownload, TransferData, and ECU Reset steps while keeping firmware artifacts, settings, logs, and traces for analysis.
Download sequence
Manage session, security, routine, download, transfer, and reset steps.
Firmware formats
Process HEX, S-record, BIN, and VBF firmware inputs and prepare download segments.
Traceable update
Preserve ASC traces, step states, failure reasons, and merged firmware details.
Bootloader bring-up
Useful for early bootloader validation and ECU update flow debugging.

Product Highlights
Supports common UDS download service sequences.
Supports HEX, S-record, BIN, and VBF firmware formats.
Keeps traces and step results for debugging and delivery review.
Core Capabilities
UDS download flow
Controls common reflash steps such as 0x10, 0x27, 0x31, 0x34, 0x36, 0x37, and 0x11.
Firmware segmenting
Prepares firmware addresses, payloads, padding, and blocks to reduce manual file handling risk.
Security Access
Integrates external seed / key calculation into the download sequence.
Logs and traces
Keeps step states, CAN traces, responses, and failure reasons for bring-up analysis.
Typical Firmware Update Workflow
From firmware loading and download configuration to step execution and trace retention, ECU update behavior can be validated repeatedly.
1
Load firmware
Import HEX, S-record, BIN, or VBF and verify addresses and segments.
2
Configure sequence
Set session, security, routine, download, and transfer parameters.
3
Run download
Execute each step and record responses, NRCs, progress, and errors.
4
Keep evidence
Export traces, logs, and firmware handling results for debug or review.
Where It Fits
Useful for bootloader validation, update flow development, firmware delivery testing, and field issue analysis.
Bootloader bring-up
Validate session switching, security, routine, and transfer behavior.
Update validation
Repeat the same sequence across firmware versions and compare results.
Failure analysis
Use NRC, trace, and step logs to analyze download interruption or ECU reset issues.
