    Hi Anping,

    We do not have WDT API for AM335x TI RTOS. We have only direct register access. Check below files for details:

    pdk_am335x_1_0_15/packages/ti/starterware/include/hw/soc_am335x.h:   #define SOC_WDT_1_REGS                       (0x44E35000)

    pdk_am335x_1_0_15/packages/ti/starterware/bootloader/src/am335x/sbl_am335x_platform.c - SBLPlatformConfig()

    pdk_am335x_1_0_15/packages/ti/board/utils/uniflash/target/board/src/board.c - socPlatformConfig()


    Regards,
    Pavel

    Anping,

    No, we do not have example projects with WDT. The only AM335x files which are using WDT, are the one I have provided in my previous e2e post.

    We have WDT example only for AM57x device.
