I need to bring an Infineon TriCore-based MCU SAK-TC397XX-256 back to life even though the original binary is long gone. The goal is to recreate the complete firmware by extracting whatever resides on the MCU, disassembling it in Ghidra (my preferred analysis environment), and rebuilding an image that can be flashed to a fresh chip with identical behaviour. Key deliverables • A safe dump of all on-chip code and data, carried out without damaging the device or triggering permanent lock-outs. • A Ghidra project containing fully labelled functions, data structures, memory map and peripheral initialisation details. • A buildable, assemble-ready firmware file that boots and operates just as the original. • Concise technical notes explaining any security bypasses, boot-loader quirks, and verification steps so another engineer can follow your process. Acceptance criteria • Re-flashed device starts and performs indistinguishably from the original hardware. • Annotated listing is clear enough for routine maintenance or feature tweaks. If you have hands-on experience with TriCore or comparable automotive MCUs and a proven workflow in Ghidra, tell me how you would tackle the dump and which hardware interfaces or adapters you plan to use. I’m ready to get started as soon as the approach and timeline look solid.
