    Rana,

    1. F28377S has 2 Flash banks, so OTA is possible. Strictly speaking, AUTOSAR FOTA on this device will require 3 Flash banks.

    2. You have to set it up properly during production, and make it OTA ready.

    3. You can start by referring to spracn0 (section 3.9), then for details you can refer to TIDM-02011 (available in the C2000 Digital Power SDK).

    4. I presume you would be able to have the host send the appropriate hex file to the appropriate target MCU.

    Thanks,

    Sira

    regarding point 2, I want to mass-produce a product. How can I set it up to support OTA updates? Can the chip supplier provide TMS320F28377s OTA ready over CAN ? ?

    Rana,

    Please refer to section 4 of tiduey4. This is the design guide of TIDM-02011, and section 4 is a FOTA section.

    We do not currently provide a CAN Flash kernel example for F2837x, but you can use the example from F28003x for DCAN (in C2000Ware at driverlib\f28003x\examples\flash\flash_kernel_ex5_dcan_flash_kernel) as a starting point and migrate.

    Thanks,

    Sira
