Pyadi Dt CLI

pyadi-dt CLI

Use adidtc to inspect, generate, validate, and deploy Linux device trees for Analog Devices hardware. Prefer discovery and read-only commands first. Treat SD card writes, property writes, and reboots as hardware-changing operations.

Start here

1. Confirm the executable and inspect the current command surface:

   command -v adidtc
   adidtc --help
   

2. If it is unavailable, from the pyadi-dt repository create an isolated environment instead of modifying the system Python:

   python3 -m venv .venv
   .venv/bin/pip install -e .
   .venv/bin/adidtc --help
   

   For XSA generation, install the XSA extra and ensure sdtgen is available:

   .venv/bin/pip install -e '.[xsa]'
   command -v sdtgen
   

3. Ask for or discover the input path, board/profile, desired output, and whether hardware mutation is allowed. Do not guess a board, IP address, credential, PetaLinux project, or output path.

4. Run the narrow command's --help before composing an unfamiliar invocation.

Route the task

See reference/commands.md for copy/pasteable recipes and output checks.

XSA-to-DTS workflow

1. Verify inputs exist and preserve them unchanged:

   test -f design.xsa
   test -f cfg.json
   python -m json.tool cfg.json >/dev/null
   adidtc xsa-profiles
   adidtc xsa-profile-show ad9081_zcu102
   

2. Use a fresh output directory. Prefer linting, and use strict validation for a release or hardware-bound artifact:

   adidtc xsa2dt \
     -x design.xsa \
     -c cfg.json \
     --profile ad9081_zcu102 \
     -o generated/ad9081-zcu102 \
     --strict-lint
   

3. When a trusted DTS exists, request parity evidence:

   adidtc xsa2dt \
     -x design.xsa \
     -c cfg.json \
     --profile ad9081_zcu102 \
     --reference-dts reference.dts \
     --strict-parity \
     --strict-lint \
     -o generated/ad9081-zcu102
   

4. Verify the command exited successfully and inspect every reported artifact. Expected outputs can include a generated overlay (.dtso), merged source (.dts), HTML report, map/coverage reports, and PetaLinux files when that format is selected. Do not claim the tree boots until it has actually been compiled and tested on the intended hardware.

5. Use --format petalinux without --petalinux-project to review generated integration files first. Copy into a real project only when the user supplied and approved its path.

Inspection workflow

Choose the least invasive context:

• local_file: read a supplied .dts or .dtb; no hardware access.
• local_sysfs: inspect /proc/device-tree on the current target.
• remote_sysfs: inspect a running board over SSH; read-only.
• local_sd / remote_sd: persistent boot media; writes are possible.

Examples:

adidtc -c local_file -f system.dtb prop -cp adi,ad9081 clock-output-names
adidtc -c remote_sysfs -i BOARD_IP prop -cp adi,ad9361 clock-output-names
adidtc -c local_file -f system.dtb props amba spi0

Replace BOARD_IP with a user-provided or independently discovered address. Keep global options before the subcommand. First identify nodes, then read the property, then propose any change.

Hardware mutation guardrails

• Do not write a property, alter SD contents, or reboot unless the user explicitly requested that side effect and identified the target.
• Never place passwords, tokens, or private keys in files, command history, reports, or the skill. Prefer existing SSH configuration or an interactive credential mechanism. Do not print secrets.
• Before sd-move or sd-remote-copy, run the identical operation with --dry-run --show, review source files and destination target, then run the real command only after explicit approval.
• Omit --reboot on the first real write unless reboot was explicitly requested.
• Preserve original XSA, DTS/DTB, boot files, and configs. Generate into a new path and report it.
• A successful generation is not hardware validation. A successful copy is not proof of a successful boot. Verify each stage separately.

Failure handling

• adidtc: command not found: use the repository venv or install in a fresh venv.
• Missing sdtgen: install lopper/XSA dependencies or source the correct Vivado/Vitis environment; do not substitute a fabricated base DTS.
• Missing dtc: generation may still produce DTS, but --compile cannot be claimed successful.
• Unknown profile: run adidtc xsa-profiles; do not invent profile names.
• Invalid config or parity/lint failure: preserve the output and report the exact diagnostic. Do not disable strict checks merely to get a green command.
• Remote connection failure: distinguish address/authentication/network failures from device-tree errors before changing the invocation.

Completion checklist

• Used an isolated environment and the actual adidtc --help surface.
• Confirmed input files, target/profile, and output path.
• Preserved source artifacts and wrote generated files to a new path.
• Used read-only context or dry-run before hardware-changing operations.
• Ran applicable lint, parity, JSON, DTS/DTB, or hardware validation.
• Reported the executed command, exit status, artifact paths, and limitations.
