DCENT_OS for Antminer S21

Current answer

DCENT_OS has earlier accepted-share runtime evidence on S21 hardware, but there is no public image or supported first-install route. Source support and bench evidence are not a customer installation promise.

ASICBM1368
Control-board laneAmlogic (documented runtime lane)
ArtifactNo public artifact
Mining evidenceMining verified on an earlier runtime path; not rerun on the latest binaries
Install readinessLab-only; stock AMLCtrl in-place installation remains blocked
Production statusNot supported for public installation

Artifact and source evidence

No download is published for this model lane. A driver, runtime proof, or lab result is not a flashable release.

Primary project evidence: per-model platform matrix, four-tier testing protocol, and GPL-3.0 source repository.

Dated evidence ledger

Website review2026-08-08
Published proof scopeThe public platform matrix records earlier sustained hashing with accepted shares on a runtime path.
Open evidence gapCurrent-binary rerun, public artifact, stock first-install path, soak and recovery capstone.
Build / commitNo model-specific commit receipt is asserted on this page; use the named artifact manifest or the current repository commit when reproducing a test.
Independent reproductionNo independent reproduction is claimed unless a dated proof link is added here.

What the status does — and does not — prove

Mining evidence answers whether DCENT_OS has produced accepted pool shares on named hardware. Install readiness answers whether a general operator can safely move from the original firmware to this build and recover. Those are independent questions.

  • Mining verified means accepted shares, not merely detected chips or nonce flow.
  • Guarded artifact means a signed file is downloadable but an install, boot, soak, or recovery proof is still incomplete or unpublished.
  • Lab-only means the source or runtime path has evidence without a general public installation route.
  • In development means there is no public artifact for operators to flash.

Known limitations

  • The accepted-share evidence has not been rerun on the latest public binaries.
  • The stock Amlogic AMLCtrl route remains an installation blocker.
  • No S21 package, checksum, release note or supported recovery route is published.

Do not infer support from the miner name alone. Identify the exact control board, keep a known-good SD/UART recovery path, and never test experimental firmware on revenue-critical hardware.

Identify the exact control board

Use the ASIC control-board reference and physical board markings before interpreting this page. Connector shape, miner family and an ASIC generation are not sufficient identifiers. No stock photo or simulated dashboard is presented as proof for this lane.

Artifact-to-evidence receipt

Exact public artifactNone published
Source commit / Git tagNot recorded in the public website receipt for this artifact; do not infer one from the current repository head.
Manifest / signatureNo public package or manifest.
Raw pool / console proofNo model-specific raw proof bundle is linked from this website page yet.
Independent reproductionNone published and linked.
Change historyUse the dated evidence ledger; no separate model changelog is claimed.

Test this exact lane and publish success or failure. A report must identify the model, board, artifact digest, source/build state, raw logs and recovery outcome.

Installation and recovery policy

Start with recovery, not features. Read the rollback and UART recovery guide and the hardware-readiness checklist. A dry run should identify the model, board family, route and backup state before any persistent write.

Performance data

No independent stock-versus-DCENT_OS benchmark dataset is asserted here. D-Central will publish hashrate, wall power, J/TH, thermals, fan RPM, reject rate and stability data only with the raw measurements, hardware identifiers, build commit, pool-side proof and test duration attached. See the benchmark and reproduction protocol.
