PiDog V2, Raspberry Pi 5, Robot HAT v5, Raspberry Pi OS Bookworm 64-bit (Trixie). imu_sh3001 and rgb_strip both fail on init. i2cdetect -y 1 is empty — all devices appear on buses 13 and 14. Servos are stiff/powered but not responding to PWM commands. All cables appear correctly seated.
Please let me know if you have any help or suggestions- best regards.
