Create Nucleo N657x0-Q Platform by bremoran · Pull Request #1547 · pq-code-package/mlkem-native

bremoran · 2026-02-05T13:21:25Z

This change introduces a new bare-metal test platform for the Nucleo N657x0-Q board and integrates it into the project’s Nix devshell and test build system.

Summary

Adds a dedicated Nix devshell target for nucleo-n657x0-q.
Introduces a full bare-metal platform under test/baremetal/platform/nucleo-n657x0-q/, including build rules, execution wrapper, argument packing utility, and platform sources.
Updates HAL and test make components to integrate the new platform.

Changes

flake.nix: Add .#nucleo-n657x0-q devshell.
nix/nucleo-n657x0-q/default.nix: Define board devshell and tooling.
nix/util.nix: Utility update for new platform.
test/baremetal/platform/nucleo-n657x0-q/README.md: Platform documentation.
test/baremetal/platform/nucleo-n657x0-q/platform.mk: Makefile integration for the platform.
test/baremetal/platform/nucleo-n657x0-q/exec_wrapper.py: Execution wrapper for running tests on target.
test/baremetal/platform/nucleo-n657x0-q/make_argv_bin.py: Helper to pack argv for target.
test/baremetal/platform/nucleo-n657x0-q/src/*.c, *.h: Platform sources (cmdline, semihosting syscall, helpers).
test/hal/hal.c, test/hal/pmu_armv8.h: Minor HAL updates for compatibility.
test/mk/components.mk: Include the new platform components.

Why

Enables running and validating ML-KEM tests on the Nucleo N657x0-Q board.
Establishes a consistent devshell and build workflow for this platform.

Usage

Devshell: nix develop .#nucleo-n657x0-q
Build tests: make test EXTRA_MAKEFILE=test/baremetal/platform/nucleo-n657x0-q/platform.mk

Notes

No breaking changes expected to other platforms.
Documentation included under the platform’s README.md.

@bremoran What's your plan for this?

bremoran · 2026-03-20T14:02:38Z

I am hoping to finalise this but I'm not able to spend time on it right now.

Is this not subsumed by the quickcheck job?

Yes, I suspect it is. I think this is because of a bad rebase; I'll prune it.

The install phase seems pretty long. Could you provide some overview in the beginning as to what is happening here?

Yes, I have added some comments that will hopefully make things clearer. I have also simplified the nix file.

Can this be part of the matrix?

Yes, agreed. I’ll add an extra_makefile field to the benchmark matrix and pass that through as EXTRA_MAKEFILE, with an empty value for the existing non-baremetal targets. That removes the target-specific expression from the step.

Why is this done here and not alongside the existing baremetal tests?

Good point. This should live with the existing baremetal workflow. I’ll move the NUCLEO-N657X0-Q job into .github/workflows/baremetal.yml as a matrix target, while keeping the self-hosted/fork guard because this one needs attached hardware rather than QEMU.

This still seems open

Does QEMU support this board, so one could, alternatively, emulate the final binary?

I don’t think QEMU currently supports the STM32N657/NUCLEO-N657X0-Q machine model. QEMU’s Arm docs list only a small set of STM32 boards, and this board is not among them; they also note that firmware images generally need an exact matching board model to boot. I’ll add a short note to the README saying this platform currently requires hardware. (qemu.org)

That said, I have just stumbled across https://renode.io which may be relevant to simulating hardware targets outside the baseline supported by QEMU.

Shallow comment: Can we keep the top-level of the platform clean and ideally confined to exec_wrapper.py, platform.mk, README.md?

Yes. I’ll move host-side helpers such as flexmem_configure.py, run_test_after_flexmem.py, make_argv_bin.py, and the host tests under the existing nucleo_host/ area, leaving only exec_wrapper.py, platform.mk, and README.md at the platform top level.

I have a fix staged, but I don't have my nucleo with me today so I cannot test it until later in the day.

hal.c seems small enough that one should be able to adjust the code instead of silencing the warnings?

Agreed. I’ll remove this per-target warning suppression and fix the warnings in test/hal/hal.c directly. The warning relaxation should stay limited to vendor/Cube sources in the platform makefile.

Would it be an option to just move all the patched files to pqmx and consume them from there?

The issue with this is the license here. If this is acceptable in pqmx, then we can move the files.

Build the mlkem-native tests as Zephyr applications so they run on QEMU-emulated Arm MPS boards spanning Cortex-M3/M4/M7/M33/M55. This greatly simplifies supporting more hardware without the need for dedicated hardware abstraction layers. Signed-off-by: Matthias J. Kannwischer <matthias@zerorisc.com>

The Zephyr platform now covers the QEMU MPS boards, so the baremetal m55-an547 and m33-an524 platforms and the pqmx package they used are no longer needed. Also drops the cross-arm-embedded dev shell and the two baremetal.yml jobs. Signed-off-by: Matthias J. Kannwischer <matthias@zerorisc.com>

This adds the platform linker scripts, semihosting glue, argv/result helpers, FLEXMEM configuration and recovery tooling, and an OpenOCD-based execution backend with host-side tests. Package the required ST OpenOCD tooling in Nix and expose a nucleo-n657x0-q development shell. Wire the platform into functional tests, component benchmarks, CI workflows, and shared bare-metal result handling, including Cortex-M cycle counter support.
