OP-TEE build.git

This repository is a temporary fork of the OP-TEE build.git project — the upstream build system for OP-TEE on open hardware platforms. It extends that build system to support Qualcomm platforms so that Qualcomm developers can work on TZ open firmware using the same tooling and workflows used across the OP-TEE ecosystem. The fork is temporary: the work here is intended to be upstreamed to the public OP-TEE repositories and retired once merged.

Build system for OP-TEE on Qualcomm platforms. Each platform has its own top-level makefile and subdirectory.

Supported platforms

Platform	SoC	Board	Makefile
Lemans	QCS9100	Qualcomm IQ-9075 EVK	lemans.mk

Quick start

# Build everything
make -f lemans.mk all

# Get Qualcomm firmware blobs for flashing (pick one):
make -f lemans.mk fetch-blobs   # fast: direct download (minutes)
make -f lemans.mk yocto         # full OE/Yocto BSP build (hours)

# Flash
make -f lemans.mk flash-loader  # bootloader chain (first-time / after TF-A change)
make -f lemans.mk flash-kernel  # EFI partition only (kernel/initramfs iteration)

Firmware blobs

Both flash-loader and flash-kernel need Qualcomm-proprietary firmware binaries (XBL, AOP, firehose programmer, GPT tables, rawprogram XMLs). These are resolved in priority order:

1. {platform}/input/ — manually placed files
2. Yocto deploy directory — if make yocto has been run
3. {platform}/blobs/ — populated by make fetch-blobs

make fetch-blobs downloads the boot binaries and CDT directly from public Qualcomm/CodeLinaro URLs and generates partition tables via qcom-ptool. No Qualcomm account is required; the download takes a few minutes.

See {platform}/input/README.md for the full file-by-file breakdown.

Documentation

HTML documentation for each platform is in docs/. Open docs/index.html as the landing page (overview, quick start, and the Lemans build/flash/boot deep dive).
