Over the air (OTA) software update for outdoor power equipment

A system that facilitates update of software for an outdoor power equipment, comprising:

• a memory configured to store instructions;
• and
• one or more processors configured to execute the instructions to:
• transmit associated version information for each microcontroller unit (MCU) of a set of MCUs of the outdoor power equipment;
• receive a first request to enter a system update state;
• initiate the system update state in response to the first request;
• receive an update binary for one or more MCUs less than the plurality of the set of MCUs;
• verify the integrity of the update binary;
• receive a second request to begin update of the one or more MCUs based on the update binary;
• and
• update the one or more MCUs with the update binary based on the received second request, wherein:
• the outdoor power equipment comprises a Vehicle Control Module (VCM), and wherein updating the one or more MCUs comprises utilizing a bootloader to program application software of the one or more MCUs from the VCM based on the update binary,
• the set of MCUs comprises a first MCU within the VCM, wherein the first MCU is configured to communicate with each other MCU of the set of MCUs over one of a Controller Area Network (CAN), a Flexible Data-Rate CAN (FDCAN), a safety FDCAN, a non-safety FDCAN, or a non-CAN communication protocol, and
• the one or more MCUs comprise a Vehicle Application Processor (VAPP) within the VCM, wherein the VCM is configured to communicate with the VAPP over the non-CAN communication interface, wherein the bootloader is a bootloader for the non-CAN communication interface within the VAPP, and
• wherein the first MCU comprises an additional bootloader, and wherein updating the one or more MCUs further comprises, prior to utilizing the bootloader:
• converting FDCAN bootloader commands to messages for the non-CAN communication interface via the first MCU;
• and
• sending the messages for the non-CAN communication interface to the VAPP over the non-CAN communication interface,
• wherein utilizing the bootloader comprises utilizing the bootloader to program application software of the one or more MCUs from the VCM based on the update binary and on the messages for the non-CAN communication interface.
