What is TE Image?
Quick note explaining TE Image for BIOS/UEFI and embedded firmware readers.
What is TE Image?
A TE image is a compact executable format derived from PE32 for firmware use.
Why it matters
- Explains how firmware is packaged into ROM/flash images.
- Helps debug missing modules, wrong FV placement, and section layout problems.
- Connects build output with what actually runs on the board.
Practical example
Example: a DXE driver may compile successfully but never run if it was not placed into the correct Firmware Volume.
Quick checklist
- Is the file/module present in the expected FV?
- Are FFS sections and DEPEX valid?
- Does the final ROM layout match the intended flash layout?
Quick takeaway
TE Image helps connect build output with the final ROM image layout.
