RZV2L: Implementation of CANFD through FSP

Hi, I have added g_canfd0 CANFD Driver in stacks. I need to initialize CANFD in hal_entry.c file.

Kindly provide some reference for RZV2L.

void R_BSP_WarmStart(bsp_warm_start_event_t event)

        /* Configure pins. */
        R_IOPORT_Open (&g_ioport_ctrl, &g_bsp_pin_cfg);

}

I want to just transmit data.

Thank you
