fix mbt build on rare errors (#3242 )

Lna investigations and fix (#3240 )
* The LNA gain field 'L' lives in LPF_VGA_2 (reg 6), not RXRF_2 (reg 2). RXRF_2 only holds LNAgain_SPI_EN. The configure_rx_gain() function wrote 'L' into lpf_vga_2 but marked RXRF_2 dirty => the LNA value only got flushed incidentally because the following VGA write marks LPF_VGA_2 dirty. Drop the stray RXRF_2 dirty flag and rely on the LPF_VGA_2 flag, which carries both L and VGA. * The baseband build defined IS_H1_R9 as the compile-time constant 0, on the (now incorrect) assumption that detected_platform() isn't linked. The sd_over_usb image is the only baseband target that compiles the IS_H1_R9-gated upstream files (rf_path.c, si5351c.c, sgpio.c, platform_gpio.c, platform_scu.c), and it *does* link platform_detect.c and call detect_hardware_platform() at startup. Forcing IS_H1_R9=0 dead-stripped every 'if (IS_H1_R9)' branch, so a real HackRF One r9 was set up with the OG clock/GPIO/RF-path config in that image. Define IS_H1_R9 as the runtime '(detected_platform()==BOARD_ID_HACKRF1_R9)', mirroring upstream platform-detect.cmake for HACKRF_ONE. All usages are '#ifdef IS_H1_R9' + 'if (IS_H1_R9)' (no arithmetic '#if'), so a function-call expression is safe, single-quoted -D with no internal spaces keeps it intact through the shell-split DDEFS blob. --------- Co-authored-by: gullradriel <gullradriel@users.noreply.github.com>

+# PortaPack Mayhem – Agent Guidelines
+
+Welcome to the PortaPack Mayhem repository. This document sets mandatory rules and best practices for human developers and AI coding assistants. It exists to prevent unverified, untested code from overwhelming the maintainers, while still enabling AI to accelerate development.
+
+## 🚫 STRICTLY PROHIBITED
+
+1. **No Fully Automated Pull Requests**  
+   Autonomous agents (bots, crawlers, automated workflows) must **never** open a Pull Request without direct human supervision, review, and explicit approval.
+
+2. **No “Blind” AI-Generated Submissions**  
+   If you cannot explain, debug, or maintain the C++/DSP code an AI produced for you, do **not** submit it. PRs that appear to be untested, AI-only “compile-and-pray” attempts will be closed immediately.
+
+3. **No Unverified Hardware Interactions**  
+   AI cannot test on real hardware. Do **not** submit code that has not been compiled and physically tested on a PortaPack device (or a highly accurate emulator). This includes UI rendering, RF transmission quality, and baseband stability.
+
+## ✅ ENCOURAGED AI USE CASES
+
+We strongly encourage using AI assistants (Copilot, ChatGPT, Claude, local LLMs) as pair-programmers. Excellent use cases include:
+
+- **Bug Triage & Root-Causing:** Analyze crash logs, stack traces, and complex memory issues to identify the root cause of an open issue.
+- **Code Comprehension:** Map Mayhem’s architecture, understand M0‑M4 IPC, or break down complex DSP algorithms.
+- **Development Assistance:** Generate boilerplate UI code, write unit tests, optimize math functions, or draft documentation – provided a human reviews and refines the output.
+- **Targeted Refactoring:** Suggest cleaner, modern C++ for small legacy code segments. **Do not attempt to rewrite the entire codebase.**
+
+## 📋 MANDATORY RULES FOR AI‑ASSISTED CONTRIBUTIONS
+
+When submitting AI‑assisted work, you must:
+
+1. **Take Full Ownership**  
+   You are strictly responsible for every line of code you submit, regardless of origin. Be prepared to answer detailed technical questions during review.
+
+2. **Hardware Verification Required**  
+   In your PR, explicitly state: *“I have compiled this code and tested it on physical PortaPack hardware.”* PRs without this statement will be rejected.
+
+3. **Transparency (Recommended)**  
+   If AI significantly helped architect a feature or fix a complex bug, mention it briefly in the PR description (e.g., *“Used an LLM to help optimize the DSP filter loop”*).
+
+4. **Adhere to Coding Standards**  
+   Ensure all code matches the existing Mayhem style and formatting before opening the PR.
+
+## ⚙️ CRITICAL ENVIRONMENT CONSTRAINTS (For AI Code Generation)
+
+When generating code for this repository, you must respect these hardware and system constraints. **Violating any of them will result in immediate rejection.**
+
+- **Severe Memory Limits** – RAM is extremely scarce. Every byte counts. Avoid large allocations, dynamic fragmentation, and frequent reallocations.
+- **Platform** – ChibiOS 2.6 on NXP LPC4320(HackRF One) / LPC4330 (HackRF Pro AKA PRALINE). M0 core handles UI; M4 core runs baseband. Baseband apps are separate executables loaded on demand at runtime.
+- **IPC** – Implemented via shared memory.
+- **Flash Size** – Very small. Code must be compact and not overly complex.
+- **No HW FPU on M0** – Floating‑point operations are expensive. Prefer fixed‑point or integer math.
+- **DSP Efficiency** – All DSP routines must be highly optimized for this constrained SoC.
+- **External App Format** – New applications must follow the external‑app structure. Create a unique folder with `main` and `ui` files, and update `external.ld` and `external.cmake`. Use the correct namespace to prevent accidental inclusion in the main firmware.
+- **Standard Library** – Avoid `std::` whenever possible. Use lightweight alternatives.
+- **C++ Usage** – Keep it simple. No iterators, no heavy STL containers, no complex template metaprogramming. Do not allocate large contiguous blocks.
+- **UI Development** – Always use the positioning macros from `ui.hpp`. Study similar existing apps for usage patterns; do not improvise.
+
+## 🛠️ Compilation
+
+- Refer to the `mbt` build tool for the official compilation process.  
+- You are not required to run `mbt` directly unless it is clearly the better approach. Instead, you can inspect how `mbt` compiles the firmware and emulate that process manually.  
+- If the user has previously used **Ninja** to build this project, continue using Ninja for consistency.  
+- Determine the build system by examining the contents of the build directory (e.g., presence of `build.ninja`).
+
+## 📢 Notice to Automated Agents and Crawlers

gullradriel	abadf35e06	Lna investigations and fix (#3240 ) * The LNA gain field 'L' lives in LPF_VGA_2 (reg 6), not RXRF_2 (reg 2). RXRF_2 only holds LNAgain_SPI_EN. The configure_rx_gain() function wrote 'L' into lpf_vga_2 but marked RXRF_2 dirty => the LNA value only got flushed incidentally because the following VGA write marks LPF_VGA_2 dirty. Drop the stray RXRF_2 dirty flag and rely on the LPF_VGA_2 flag, which carries both L and VGA. * The baseband build defined IS_H1_R9 as the compile-time constant 0, on the (now incorrect) assumption that detected_platform() isn't linked. The sd_over_usb image is the only baseband target that compiles the IS_H1_R9-gated upstream files (rf_path.c, si5351c.c, sgpio.c, platform_gpio.c, platform_scu.c), and it does link platform_detect.c and call detect_hardware_platform() at startup. Forcing IS_H1_R9=0 dead-stripped every 'if (IS_H1_R9)' branch, so a real HackRF One r9 was set up with the OG clock/GPIO/RF-path config in that image. Define IS_H1_R9 as the runtime '(detected_platform()==BOARD_ID_HACKRF1_R9)', mirroring upstream platform-detect.cmake for HACKRF_ONE. All usages are '#ifdef IS_H1_R9' + 'if (IS_H1_R9)' (no arithmetic '#if'), so a function-call expression is safe, single-quoted -D with no internal spaces keeps it intact through the shell-split DDEFS blob. --------- Co-authored-by: gullradriel <gullradriel@users.noreply.github.com>	2026-07-01 08:47:07 +02:00

Arne Luehrs	c7a0846645	EPIRB RX: add receiver-overload indicator on channel bar (#3212 ) * EPIRB RX: add receiver-overload indicator on channel bar Tint the channel-power bar red when the front-end overloads (ADC near full scale). EPIRB demodulation relies on the constant-envelope carrier and the +/-1.1 rad biphase phase jumps; ADC clipping distorts both, so a visible cue to reduce RF-amp/LNA/VGA gain is useful. Implemented in the shared ui::Channel widget via an opt-in set_overload_threshold(): when the last ChannelStatistics max_db reaches the threshold the bar is drawn red instead of blue. Default threshold is above the 0 dBFS ceiling, so all existing users are unaffected. The EPIRB view enables it at -3 dBFS. Done in the widget (main firmware) rather than the EPIRB app because the epirb_rx external app is already at the 32 KB flash limit; the app only pays for a single setter call.	2026-06-11 11:10:23 +02:00
Arne Luehrs	569bcaad22	Epirb afc wide capture (#3213 ) * EPIRB RX: widen AFC capture range to +/-5 kHz The AFC estimate was only applied after carrier lock, so carrier acquisition ran on raw phase deltas and could only tolerate offsets of a few hundred Hz before the 0.6/0.7/1.6 rad detection thresholds (on the 12-sample accumulator) broke down. Track the carrier offset continuously in the IDLE state with a first-order loop (AFC_TRACK_ALPHA), so the de-biased accumulator self-centers for any offset within the discriminator Nyquist (~24 kHz) before the thresholds run. ALPHA = 0.005 pulls a +/-5 kHz offset under the 0.6 rad lock threshold in ~11 ms, well inside the 160 ms preamble / 80 ms stability window. The IDLE rise-detect threshold is also made symmetric (fabsf) now that the bias is removed. Also add the missing <cstdint> include to test_convert.cpp so the application_test suite compiles under the current toolchain. Verified: baseband_epirb_rx.elf builds (flash 53%, RAM 12%) and baseband_test passes.	2026-06-11 11:01:54 +02:00

gullradriel	8f5b25b10d	PRALINE Tx and clock fix (Pr 3192 takeover (#3198 ) ) * fix clock init and add mayhem tx capacity * aligned external clock and RX config * fix(clock): cap TX interpolation to x16 to prevent doubled waveform speed The TX gateware only implements interpolation factors x1..x16 (tx_intrp 0..4), but the rate search could select n==5 (x32) for very low TX sample rates. That left the AFE/CLK0/CLK1 running at the x32 rate while the FPGA only interpolated by x16, clocking the TX datapath at twice the gateware output rate. Cap afe_rate and _resampling_n to the x16 limit in TX so the clocks stay aligned with the interpolation setting. * fix(praline): source PLL1 from 40MHz GP_CLKIN instead of 12MHz XTAL For the intermediate 90-110MHz PLL1 stepping stage, source PLL1 from GP_CLKIN (Si5351 CLK2/MCU_CLK at 40MHz) giving N=2, M=10, Fclk=100MHz, rather than the on-chip 12MHz XTAL bootstrap path. This matches the non-PRALINE path. Remove the dead commented-out XTAL enable/PLL code. * docs(fpga_bridge): correct register 0x03 description for PRALINE gateware Register 0x03 is RX_DIGITAL_GAIN in RX and TX_NCO_CTRL in TX, not RX_PSTEP. * Fix fpga_tx_set_nco_enable to use FPGA_REG3_TX_NCO_CTRL (0x03)	2026-05-31 12:44:40 +02:00
