QEMU U-Boot Build
Audit workflow
For non-trivial workspace writes, use a stable
.oh-my-qemu/<task-slug>/ directory and create only needed entries:
.oh-my-qemu/<task-slug>/
├── audit.md # Baseline, scope, decisions, evidence, verification, and gaps
├── commands.md # Redacted commands, working directories, and results
├── logs/ # Decisive build, test, runtime, or diagnostic logs
├── scripts/ # Temporary scripts, probes, parsers, and harnesses
└── output/ # Generated deliverables, dependencies, and non-QEMU binaries
Before changing source or mutable artifacts, record the workspace root,
revision, git status --short, pre-existing changes, goal, scope, and
acceptance checks in audit.md. Log exact redacted commands and results in
commands.md; record revisions, configurations, tool versions, and hashes when
they affect reproducibility. Separate observations from inferences and edit
source only when requested.
Keep QEMU builds under source-root builds/build-<target>/; put third-party
dependencies and non-QEMU binaries in task output/. Before writing audit
artifacts or configuring QEMU in a Git worktree, add .agents/,
.oh-my-qemu/, and builds/ to the repository-local file from
git rev-parse --git-path info/exclude; preserve existing entries and avoid
duplicates. Never stage or commit those directories. At handoff, verify them
absent from git status --short. Report the task directory and unresolved gaps.
Build Flow
Record:
- U-Boot source path, revision, and dirty state;
- board defconfig and any config fragments;
- architecture, cross compiler prefix, compiler version, and output directory
under
.oh-my-qemu/<task-slug>/output/; - external dependencies such as BL31, TEE, firmware blobs, device trees, or DDR init binaries;
- output artifacts such as
spl/u-boot-spl,u-boot,u-boot.bin,u-boot.itb, or platform-specific combined images; - exact command, log path, and hashes.
Command Shape
Use local documentation first. Typical U-Boot patterns are:
make O=<task-output>/uboot <board_defconfig>
make O=<task-output>/uboot CROSS_COMPILE=<prefix> -j$(nproc)
If a firmware chain requires environment variables such as BL31, record their resolved paths and hashes before building.
Output Rules
- Treat each boot stage as a separate provenance item.
- Keep dependency packages and all U-Boot build outputs under
.oh-my-qemu/<task-slug>/output/. - Do not assume a combined image contains the expected stage; inspect and record the packaging command.
- If firmware reaches U-Boot but Linux does not boot, separate U-Boot command/environment issues from QEMU model issues.

Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
