Empty initrd for display, add rp1_dsi module

ALL RP1 hardware (gpio, clocks, dsi) sits behind the RP1 PCIe southbridge, which isn't ready until ~12s. Loading any display module in initrd (~3s) crashes the system. Nothing in initrd now: - boot.initrd.kernelModules: empty (nothing touches RP1 early) - boot.kernelModules: vc4, panel_cwu50, rp1_dsi (stage-2)
Revert vc4/panel_cwu50 to boot.kernelModules (stage-2 loading)

Author	SHA1	Message	Date
Hermes	ca3faf40cf	Empty initrd for display, add rp1_dsi module ALL RP1 hardware (gpio, clocks, dsi) sits behind the RP1 PCIe southbridge, which isn't ready until ~12s. Loading any display module in initrd (~3s) crashes the system. Nothing in initrd now: - boot.initrd.kernelModules: empty (nothing touches RP1 early) - boot.kernelModules: vc4, panel_cwu50, rp1_dsi (stage-2)	2026-06-09 23:14:44 -04:00
Hermes	4f1864af70	Revert vc4/panel_cwu50 to boot.kernelModules (stage-2 loading) Loading via boot.kernelModules ensures they're loaded after initrd, by which time RP1 PCIe southbridge is initialized (~12s). This avoids the 'Cannot find any crtc' error from premature probe. - boot.kernelModules: explicit vc4 + panel_cwu50 (stage-2) - boot.initrd.kernelModules: only ocp8178_bl (backlight)	2026-06-09 22:46:43 -04:00
Hermes	67418f037a	Rex timing: remove vc4/panel_cwu50 from boot.kernelModules too Let udev auto-load display modules when RP1 PCIe southbridge appears on the bus (~12s). This is exactly how Rex's Debian image works — no forced loading in initrd or stage-2. - boot.initrd.kernelModules: only ocp8178_bl (backlight only) - boot.kernelModules: no display modules (udev handles it) - SDDM disabled (Hyprland kept for manual start)	2026-06-09 22:44:45 -04:00
Hermes	fb01e4be1d	SDDM disabled, Hyprland kept (manual start only) - Removed SDDM display manager (was blocking boot when display fails) - Kept Hyprland installed for manual start (hyprland command) - Display modules load in stage-2 via boot.kernelModules (Rex timing)	2026-06-09 22:39:13 -04:00
Hermes	f57f2846ff	Fix duplicate boot.kernelModules, merge vc4/panel_cwu50 into existing list	2026-06-09 22:20:27 -04:00
Hermes	288b7538d5	Fix CM5 display: delay vc4/panel_cwu50 to after RP1 PCIe init Loading display drivers in initrd (~3s) before RP1 PCIe southbridge is ready (~12s) causes 'Cannot find any crtc or sizes' because the DSI encoder isn't reachable. Rex loads these via udev late in boot. - boot.initrd.kernelModules: only ocp8178_bl (backlight, RP1-independent) - boot.kernelModules: vc4 + panel_cwu50 loaded in stage 2 after RP1	2026-06-09 21:42:24 -04:00
Hermes	fb7c3e6424	Fix RNS setup.py license_files tuple for setuptools 80.x	2026-06-09 20:49:16 -04:00
Hermes	6961027218	Fix reticulum build: add sourceRoot for PyPI package	2026-06-09 20:47:45 -04:00
Hermes	8bf44a066e	Add nixpkgs-uconsole pinned to commit that base image used The base image (nixos-uconsole v1.1.0) was built with nixpkgs commit 54170c54449ea4d6725efd30d719c5e505f1c10e (2026-04-10), NOT the flake.lock pin (89dbf01df7 from Dec 2025). By pinning to the exact commit the image used, the kernel derivation hash should match what's already in the store.	2026-06-09 20:38:05 -04:00
Hermes	644c9a7645	uConsole: use mkUConsoleSystem instead of manual nixosSystem Using nixos-uconsole.lib.mkUConsoleSystem ensures the exact same module composition as the pre-built image, so the kernel derivation hash matches what'\''s already in the store (6.12.47).	2026-06-09 20:16:31 -04:00
Hermes	52fa439409	Align pins with nixos-uconsole v1.1.0 for kernel cache hit - nixos-uconsole: main -> v1.1.0 (tag) - nixos-raspberrypi: v1.20260517.0 -> v1.20260317.0 (matches nixos-uconsole v1.1.0's flake.lock) - Keeps nixos-raspberrypi.inputs.nixpkgs.follows = nixos-uconsole/nixpkgs This ensures the kernel derivation hash matches the pre-built image's kernel already in the uConsole store.	2026-06-09 19:52:40 -04:00
Hermes	db2deda941	fix(uconsole): align nixos-raspberrypi nixpkgs with nixos-uconsole Make nixos-raspberrypi follow nixos-uconsole's nixpkgs so the kernel uses the same nixpkgs that the uconsole Cachix was built with.	2026-06-09 19:34:31 -04:00
Hermes	7f7634c1b1	fix(uconsole): stop following nixpkgs for nixos-uconsole and nixos-raspberrypi Remove inputs.nixpkgs.follows so these inputs use their own pinned nixpkgs. This lets the uConsole build use the nixos-uconsole Cachix cache for the kernel, avoiding 4h kernel recompilation on every config change.	2026-06-09 19:23:53 -04:00
Hermes	1fa1cfaa76	fix(uconsole): apply CM5 display fixes from nixos-uconsole comparison - Add hardware.graphics.enable = true (Mesa GPU required for VC4) - Add boot.kernelParams with console=tty1 (console on fb0 not ttyAMA0) - Fix console.font to ter-v24n with proper package (match nixos-uconsole) - Merge GPIO 10/11 from nixos-uconsole extra-config (audio amp) - Bump stateVersion to 25.11	2026-06-08 23:40:19 -04:00
Hermes	4d2cba77e1	fix(display): use [pi5] config.txt section instead of [cm5] Rex's Trixie images use [pi5] for the CM5 display overlays (clockworkpi-uconsole-cm5, vc4-kms-v3d-pi5). The nixos-uconsole module generates [cm5] which the firmware may not apply on some CM5 EEPROM configurations. Adding explicit [pi5] section ensures the display overlays are always loaded.	2026-06-07 22:49:01 -04:00
Hermes	8d54e5e8fa	fix(display): use kernel default console font instead of ter-v24n The ter-v24n Terminus font renders garbled on CM5 DSI 720x1280 panel (green stretched line across screen). Switching to the kernel's built-in Lat2-Terminus16 font for correct text rendering.	2026-06-07 22:10:46 -04:00
Hermes	42e5d4dd2d	fix(uconsole): disable GPIO 23 service (causes CM5 freeze) + open SSH GPIO 23 service used gpioset 0 23=1 on BCM2712 chip 0 instead of the RP1 chip (base 512), writing to a critical pin and freezing the system. Commented out until correct chip is confirmed. SSH opened with PasswordAuthentication + PermitRootLogin for first deployment. Lock down after initial boot.	2026-06-07 21:57:13 -04:00
Hermes	682402e0e6	fix(uconsole): use nixpkgs default nix instead of lix dev lix dev (20260606) is incompatible with nixpkgs 25.11 stable. Still on other hosts. This avoids the lix build failure.	2026-06-07 10:08:35 -04:00
Hermes	9c4b50b4c3	fix(config): remove meshtastic from packages — not in nixpkgs 25.11	2026-06-07 06:47:32 -04:00
Hermes	8e395729ff	fix(overlay): avoid recursion with final.lib, use prev.lib.optionalAttrs Replace recursive `final.lib.optionalAttrs` with `prev.lib.optionalAttrs` using the `?` operator to check for meshtastic existence safely. This allows the overlay to work with both stable (25.11) and unstable.	2026-06-07 06:45:16 -04:00
Hermes	346b41995f	fix(overlay): make meshtastic conditional for stable nixpkgs (25.11) meshtastic package doesn't exist in nixpkgs 25.11 stable. Use optionalAttrs to skip the override when not available, allowing the flake to build against both stable and unstable.	2026-06-07 06:43:09 -04:00
Hermes	68900ca7b3	fix: switch to nixpkgs 25.11 stable to match pre-built uConsole kernel The uConsole CM5 has kernel 6.12.47 in its store from the nixos-uconsole-cm5-v1.1.0 image (built with nixpkgs 25.11). By switching to the same nixpkgs version, Nix will reuse the existing kernel instead of rebuilding it from source.	2026-06-07 06:37:25 -04:00
Hermes	38eea77fd9	fix(uconsole): remove useless udev rule for voltage_min_design sysfs node is read-only (0444), even root cannot write. The AXP228 PMU manages power path in hardware. Practical fix: disconnect batteries during heavy builds.	2026-06-06 23:01:14 -04:00
Hermes	b7b5ef0b53	fix(uconsole): lower voltage_min_design to 2.7V to prevent random power-off under heavy CPU load	2026-06-06 22:54:59 -04:00
Hermes	f0954efcaa	fix(sddm): enable wayland support for Hyprland	2026-06-06 21:29:51 -04:00
Hermes	b0be414649	revert(nixos-uconsole): follow unstable nixpkgs again Cachix has no CM5 kernel anyway, so sticking to stable doesn't save build time. Might as well stay on unstable for latest pkgs.	2026-06-06 21:27:47 -04:00
Hermes	31dd0f36d4	feat(uconsole): add Hyprland + SDDM display manager Enables Hyprland Wayland compositor with XWayland support and SDDM display manager for graphical desktop on the uConsole CM5.	2026-06-06 21:23:15 -04:00
Hermes	653c69fcfd	fix(flake): detach nixos-uconsole nixpkgs from unstable to hit Cachix nixos-uconsole's Cachix cache is built with nixpkgs-stable (25.11). Following our unstable caused a full kernel rebuild every time. By using nixos-uconsole's pinned nixpkgs, future builds will download the pre-compiled kernel from the cache instead of compiling it locally on the CM5.	2026-06-06 21:07:37 -04:00
Hermes	a9b95c5d48	fix(config): use libgpiod instead of gpiod for gpioset The nixpkgs attribute for userspace GPIO tools is 'libgpiod', not 'gpiod'. This provides the gpioset binary used by the GPIO 23 internal USB hub service.	2026-06-06 17:27:12 -04:00
Hermes	6771c9882a	fix(hw-config): use mkForce for filesystems to avoid disko conflict Disko auto-generates fileSystems with by-partlabel paths, but for manual install via loop devices we need by-label paths. mkForce ensures our paths win during evaluation.	2026-06-06 17:23:50 -04:00
Hermes	897f470a16	fix(disko): use /dev/mmcblk0 instead of wrong by-path platform-fe340000.mmc doesn't exist on the uConsole CM5. The eMMC is at /dev/mmcblk0 in normal boot mode.	2026-06-06 16:51:46 -04:00
Hermes	eaf879c4d1	fix(disko-config): use disko.devices.disk instead of top-level disk disko module defines options under `disko.devices.disk.`, not `disk.`. This was causing evaluation error: "The option 'disk' does not exist. Did you mean 'disko'?"	2026-06-06 16:39:46 -04:00
Hermes	486758e51a	feat(uConsole): add disko, backlight fix, GPIO 23, mt7921u - Add disko flake input + partition config (/boot/firmware, /, /home) - Add cm5-backlight-fix service as display fallback - Add enable-gpio23-usb-hub service for internal USB hub - Add mt7921u kernel module for MediaTek AC1200 WiFi - Add gpiod package for GPIO userspace control	2026-06-06 16:38:41 -04:00
Hermes	34cc0a161a	fix: override meshtastic to skip runtime deps check (tabulate 0.10.0 incompatibility)	2026-06-06 10:17:04 -04:00
