TM4C123GH6PM: Tivaware CAN Bootloader

Part Number: TM4C123GH6PM

I'm trying to build and use the sample bootloader code provided in the Tivaware library files, as specified in the Tivaware bootloader user guide(http://www.ti.com/lit/ug/spmu301d/spmu301d.pdf

CAN_UART_BRIDGE

    Hi,
    What is your question? It is not clear to me? We do have ready to use UART-based bootloader example in TivaWare library. The TivaWare bootloader library supports CAN-based bootloading but there is no ready to use example.

    Hello,

    Sorry I wasn't clear. My question is, what does the CAN_UART_BRIDGE option in bl_config.h in the Tivaware bootloader library do? I'm trying to use that library to create a CAN bootloader, and I'm wondering if that option helps transfer programming commands from UART to CAN.

    Hi Evan,
    If your sole communication method for bootloading is CAN then you don't need to define CAN_UART_BRIDGING. Looking at the source code, once CAN_UART_BRIGING is defined, it allows bridging between from CAN to UART and vice versa. To simply your design I will suggest you stick without the CAN_UART_BRIDGING for now and later explore the CAN_UART bridging capability should this need arises.

    Hello Charles,
    Thank you for the clarification. I'll take your advice and get CAN functionality working first, before I go any farther with bridging.
    Thank you very much.
