Antminer S21 XP DCENT_OS Firmware: Release, Compatibility & Recovery
Current answer
Antminer S21 XP is Released on the Experimental channel. Exact topology and package-source evidence are public, while mining runtime, verified binary, installation and recovery remain unavailable as operator routes.
| Availability | RELEASED — publicly released on the Experimental channel |
|---|---|
| Maturity | EXPERIMENTAL — not Stable or GA; not recommended for irreplaceable production hardware |
| ASIC | BM1370 (230 chips per chain in the evidenced profile) |
| Control-board lane | Amlogic am3-s21xp; package and exact topology evidence only |
| Prebuilt binary evidence | No verified S21 XP prebuilt binary is listed in the current artifact ledger. |
| Mining evidence | The source records exact topology and package-format evidence, but the installed runtime remains management-only and no accepted-share proof is claimed. |
| Install readiness | The am3-s21xp install row has no implemented update mechanism, denies installation and authorizes no persistent update. |
| Recovery readiness | No external-media, installation-write or recovery route is published. |
| Production alternative | Experimental — use exact vendor stock or a mature, independently suitable production firmware for revenue-critical hardware. Compare production choices. |
Artifact and source evidence
This model is Released/Experimental, but no verified model-specific prebuilt binary is listed in the current artifact ledger. Use the public source and evidence record for development and review. Do not rename or repurpose a file from another model.
Inspect the complete artifact ledger or build and audit the source.
Primary project evidence: per-model platform matrix, four-tier testing protocol, and GPL-3.0 source repository.
Dated evidence ledger
| Website review | 2026-08-29 |
|---|---|
| Published proof scope | Exact BM1370/Amlogic topology and package-format source evidence. |
| Open evidence gap | Prove safe runtime ownership, accepted shares, a verified artifact and reversible install/recovery. |
| Build / commit | No model-specific commit receipt is asserted on this page; use the named artifact manifest or the current repository commit when reproducing a test. |
| Independent reproduction | No independent reproduction is claimed unless a dated proof link is added here. |
What the status does — and does not — prove
Release availability, maturity, binary evidence, mining evidence, installation and recovery are independent questions. A positive answer on one axis never silently promotes another.
- Released means this model is publicly included on the DCENT_OS Experimental channel.
- Experimental means public test firmware, not Stable/GA or a risk-free production recommendation.
- Verified prebuilt means the current ledger records a real file, byte size and SHA-256 for the exact lane.
- No verified prebuilt in the current ledger is a binary-evidence limitation, not an unreleased-model status.
- Mining accepted requires accepted pool shares; detection or nonce flow alone is labelled separately.
- Lab-only or denied installation remains binding even though the model is Released/Experimental.
Known limitations
- S21 XP must not inherit the S21 or S21 Pro serial topology.
- A package format in source is not a verified public binary.
- Persistent update is not authorized.
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 verified prebuilt | No verified model-specific prebuilt is listed in the current ledger; the model remains Released/Experimental. |
|---|---|
| Source commit / Git tag | Not recorded in the public website receipt for this artifact; do not infer one from the current repository head. |
| Manifest / signature | No model-specific prebuilt package signature is asserted. |
| Raw pool / console proof | No model-specific raw proof bundle is linked from this website page yet. |
| Independent reproduction | None published and linked. |
| Change history | Use 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
Exact model status: The am3-s21xp install row has no implemented update mechanism, denies installation and authorizes no persistent update.
Recovery boundary: No external-media, installation-write or recovery route is published.
Start with recovery, not features. Read the rollback and UART recovery guide, stock-restoration boundaries and the hardware-readiness checklist. If this page does not name an authorized route for your exact board, do not flash it.
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.
