Add an isolated SAFE24 QVGA capture, CPU statistics and SDIO save/readback
image with passive transaction observers. Keep ordinary images, production
RTL, public interfaces and dependency versions unchanged.
Retain matched binaries and source-bound stage evidence, distinguish
software comparisons from architectural measurements, and reject invalid
terminal results or incompatible resume inputs. Count SDIO descriptors and
status writebacks separately from pixel payload.
Validation on the final worktree includes 2031 passed / 1 skipped Pytest
tests, C format/policy/host checks, and directed observer tests on Icarus
and Verilator. Selected ICS55 and IHP130 SAFE24 campaigns and compact
backend checks pass; negative STA and warning observations are retained.
Complete P10 acceptance remains pending final regression and human review.
Specification: docs/ip/tiny-soc.md, TINY-R2-P10.
Connect DVP to Tiny DMA2/request 11, IRQ15 and the camera pad/reset lifecycle.
Harden shared capture CDC, frame statistics, per-row size validation and HAL
cleanup while preserving the Mini DMA3 binding and existing register ABI.
Add deterministic capture/recovery firmware, source-bound evidence tooling,
focused RTL/host tests and compact netlist acceptance. Preserve SAFE24,
128 KiB main SRAM, private Crypto storage and the locked dependencies.
Retained validation: focused RTL, host/policy checks, Mini firmware, and
ICS55/IHP130 RECOVERY, QVGA, synthesis and boot/DVP netlist checks pass.
Full-system VGA remains historical; long full Icarus and broad regressions
remain deferred. Global publication/format gaps and negative observational
STA are retained, not reported as passing qualification.
Specification: docs/ip/tiny-soc.md, TINY-R2-P9.
Evidence: docs/ip/tiny-soc-verification.md.
Integrate the Tiny RCU, normalized REF24 control, external-input profiles,
single PLL backend, SYS/MEM/PCLK clocks, CPU-only WFI gating, peripheral
lifecycle control and retained debug behavior. Keep CPU and all 32 main
SRAM macros on SYS and the six private Crypto macros on PCLK.
Add the handwritten RCU register/HAL contract, RS_EBUSY, bounded SDK
operations and focused firmware. Preserve shared-IP defaults and the
ICS55/PLL SAFE24 boot and explicit IHP130/no-PLL compatibility profiles.
Use APB/AXI domain bridges and source-owned response holders to preserve
backpressured responses, complete aborted bursts and prevent stale replay.
Verify production DMA source-reset drain and common XPI endpoint reset
with extracted integration bindings and an independent scoreboard.
Add source-bound macro/clock audits, SAFE24 observational STA constraints
and commercial-adapter host checks. No P8 functionality or operating-point
qualification is included. See TINY-R2-P7 in docs/ip/tiny-soc.md.
Validation: 54 P7 directed tests pass, including both simulators, ten
source-reset ratio runs and two expected-negative drain mutations.
RTL format/style, clock/reset inventory, Ruff and both Tiny PDK PR dry-runs
pass. Retained 06-00 synthesis and strict netlist boots pass for both PDKs;
STA remains negative and observational. Source comparison confirms only
the follow-up tests changed after that backend campaign.
Evidence: build/ics55-tiny-2026-10-14-06-00-ff4b5cef6eb5/meta/
tiny-r2-p7-source-reset/summary.json. Earlier firmware, HAL and compatibility
results and the non-clean full-suite attempt retain their original
attribution. Full Icarus firmware is deferred to final Tiny qualification;
this commit does not constitute human phase acceptance or physical signoff.
Record parent and child process IDs for diagnostics, persist interruption
before cleanup, and ignore repeated termination signals during cleanup.
Close unexpected failures with a terminal result and retain the child's
exit status without treating namespace-local PID absence as completion.
Require a successful terminal run_flow result when checking simulation
logs with an associated result file. Cover repeated cancellation and
reject running, failed or inconsistent terminal records despite PASS text.
This supports the TINY-R2-P7 campaign. Interrupted and timed-out runs remain
non-acceptance evidence; UART output alone cannot qualify a Tiny simulation.
Integrate RNG, CRC, WS2812, Crypto, I2S master and the SDIO private AXI owner on SAFE24. Preserve the 128 KiB main SRAM and six private Crypto macros, add product-specific DMA assignments and reject unsupported SDK operations.
Correct APB read strobes, I2S receive assembly and SDIO command timing, backpressure and descriptor retirement. Add pin-level workloads, source-bound evidence checks and publication/commercial consumer compatibility.
Validation of the final P6 worktree: 1726 pytest tests passed with one optional pypdf skip (exit 0, 4021.61 seconds; terminal session 36439). Both PDKs passed both RTL simulators, netlist boot and 38-macro binding checks. Shared formal, Mini compatibility and software/source quality gates passed.
Evidence remains attributed to the retained dirty-worktree snapshots based on b3b30a72cd under build/ics55-tiny-2026-10-12-11-50-2eb98c0e1fae/meta/tiny-r2-p6/. Timing is negative and warning observations are not promoted. This commit does not accept P6, qualify physical operation or enable P7.
