sl-firmware 0207c29d8c fix: Resolve all 7 compile errors and 4 linker errors (Issue #337)
COMPILE FIXES:
1. battery.c: Added #include <stdbool.h> for bool type
2. main.c: Updated buzzer_play() to buzzer_play_melody(MELODY_STARTUP)
3. main.c: Replaced bno055_active with bno055_is_ready() calls
4. servo.c: Removed duplicate ServoState typedef from .c file
5. ultrasonic.c: Added forward declaration for HAL_TIM_IC_Init_Compat
6. fan.c: Fixed HAL_TIM_PWM_Start to use handle &htim1 instead of register
7. watchdog.c: Created static IWDG_HandleTypeDef and updated refresh call

LINKER FIXES:
1. i2c1.h/c: Added i2c1_write() and i2c1_read() function implementations
2. servo.c: servo_tick() already exists (verified)
3. bno055.h/c: Added bno055_calibrated() function
4. main.c: Added imu_calibrated() wrapper for bno055_calibrated()
5. crsf.h/c: Added crsf_is_active() function

All 11 errors fixed. Build should now succeed.

Jetson Nano — AI/SLAM Platform Setup

Self-balancing robot: Jetson Nano dev environment for ROS2 Humble + SLAM stack.

Stack

Component Version / Part
Platform Jetson Nano 4GB
JetPack 4.6 (L4T R32.6.1, CUDA 10.2)
ROS2 Humble Hawksbill
DDS CycloneDDS
SLAM slam_toolbox
Nav Nav2
Depth camera Intel RealSense D435i
LiDAR RPLIDAR A1M8
MCU bridge STM32F722 (USB CDC @ 921600)

Quick Start

# 1. Host setup (once, on fresh JetPack 4.6)
sudo bash scripts/setup-jetson.sh

# 2. Build Docker image
bash scripts/build-and-run.sh build

# 3. Start full stack
bash scripts/build-and-run.sh up

# 4. Open ROS2 shell
bash scripts/build-and-run.sh shell

Power Budget (Summary)

Scenario Total
Idle 2.9W
Nominal (SLAM active) ~10.2W
Peak 15.4W

Target: 10W (MAXN nvpmodel). Use RPLIDAR standby + 640p D435i for compliance. See docs/power-budget.md for full analysis.
