Committed at docs/evidence/stage1-from-source.txt. This is what grounds the requirements
that cite it.
The board boots a stage 1 this flake compiled (tasks 5.1, 5.2)
==============================================================
2026-09-22. The image is /nix/store/vs5mll0vif0lnq36srm6qxgx75mgwf5m-k230-sd-image.img,
the pure `nix build .#sdImage` recorded in docs/evidence/stage1-from-nix.txt §6: SPL,
U-Boot 2022.10, the environment and OpenSBI 1.4 all built by this flake from pinned
sources, with OpenSBI passing the device tree through (docs/evidence/opensbi-fdt-passthrough.txt).
Who did what. The flash and every command on the board below were run by the
coordinator of this change, in their own session, because the board is a single
shared resource held by another change's agent. The agent that wrote this file did
not touch the board. Everything under "Observed" is quoted from the coordinator's
report verbatim; the transcript at the end is the coordinator's serial capture.
Observed (coordinator's session)
--------------------------------
- Reached the NixOS login prompt; uptime 0:00 at first check; no panic, no emergency shell.
- The board hashed its OWN card (/dev/mmcblk1) raw slots:
spl@1MiB fe3d537f (len 223348)
uboot@2MiB 805bd543 (len 361896)
/boot/fw_jump_add_uboot_head.bin 9627edbe
Those are the from-source binaries -- result-stage1/SHA256SUMS in stage1-from-nix.txt §6
lists fe3d537f62c3..., 805bd5434a48..., 9627edbeea9b... -- so the BootROM ran this
flake's SPL, the SPL ran this flake's U-Boot, and U-Boot ran this flake's OpenSBI.
- dmesg: `canaan-mipi-dsi 90850000.dsi: DSI PHY: lane 594000 kbps, voc 0x17, hsfreqrange 0x87`
at 3.16 s.
- The line "Kernel module BTF mismatch detected" is ABSENT from this boot (it was present
on every boot with the vendor OpenSBI).
- `dd if=/sys/kernel/btf/vmlinux bs=1 skip=$((0x3875c)) count=8 | od -An -tx1`
-> `ee c6 00 00 f5 13 00 00`
BTF bytes; on the vendor firmware the same offset read `d0 0d fe ed 00 01 24 a0`
(docs/evidence/opensbi-fdt-lands-in-kernel-image.md). The pass-through fix works on hardware.
- Panel lit: a white framebuffer fill photographed at mean brightness 204 in the panel region.
What was NOT observed
---------------------
This serial capture was opened after stage 1 had scrolled by. A second, cold-boot
capture from power-on exists -- docs/evidence/boot-from-source-cold.txt -- and it holds
U-Boot's bootm relocation lines and the full OpenSBI banner (Next Arg1 0x0a0eb000: the
device tree passed through where bootm put it). It still holds no `U-Boot SPL 2022.10`
banner, no `PMU Major Msg:` training sequence and no `U-Boot 2022.10` banner, and that
file says why: the CH342 bridge loses power with the board and takes ~3.4 s to
re-enumerate, which is the window stage 1 prints in. That the SPL trained the DRAM and
that U-Boot ran is inferred from what follows -- a kernel that only U-Boot's blinux could
have loaded, from a card whose stage-1 slots hash to this flake's output -- not seen.
Task 5.2 asks for the banner and the training messages and stays unticked. The slot
hashes plus the boot are the grounding this file offers.
