AI OTA Update System Design

OTA done badly bricks devices. The download fails halfway and leaves a corrupt image. The signature is not verified and a malicious image installs. The atomic swap is not atomic and a power loss mid-flash leaves the device unbootable. The rollback path does not exist and a bad firmware spreads across the fleet before anyone notices.

The /volt-ota skill builds the OTA system with the safety properties firmware updates need: dual-partition A/B storage so the new image is written to the inactive bank, signature verification before the swap, resumable download so connection loss does not corrupt the image, atomic partition swap, and automatic rollback if the new firmware fails to boot or fails its self-check.

What the OTA system includes

Five layers. A/B partition manager. Signature verification (ECDSA or RSA, with the public key burned into the bootloader). Resumable download with chunk verification. Atomic swap on boot. Rollback timer: if the new firmware does not check in within N boots, fall back to the previous image.

Tonone's /volt-ota skill builds OTA update systems with A/B partitions, signed images, resumable downloads, atomic swap, and automatic rollback.

/volt-ota

Builds a complete OTA firmware update system: dual-partition A/B storage with partition manager configuration, firmware image signature verification to prevent unauthorized updates, download with resume capability on connection loss, atomic partition swap, and automatic rollback if the new firmware fails to boot successfully.

/volt-firmware

Scaffolds a complete embedded firmware project for a target MCU: RTOS task structure with stack size planning, peripheral initialization sequences, power management state machine, communication stack (BLE, MQTT, or serial protocol), OTA update client, and CI build configuration. Available for ESP-IDF, STM32 HAL, Zephyr, and Arduino frameworks.

/volt-driver

Writes a device driver or protocol handler with a clean HAL abstraction layer: I2C and SPI sensor drivers with interrupt-driven I/O, BLE GATT service implementations, MQTT client with reconnection logic, or Modbus RTU handlers. Designed to be unit-testable and portable across hardware revisions.

When integrating a new sensor, peripheral, or comm…
