We are using i.mx6ul mpu and multiplexing flexcan1 on pins LCD_DATA08 & LCD_DATA09, but no luck.

dts changed as follows:


pinctrl_flexcan1: flexcan1grp{
    fsl,pins = <
        MX6UL_PAD_LCD_DATA08__FLEXCAN1_TX 0x1b020
        MX6UL_PAD_LCD_DATA09__FLEXCAN1_RX 0x1b020


No signal occurs on the LCD_DATA08 pin when can sending, checked using oscilloscope.

What issue can it be? Any special care should be taken when using LCD pins?

We are stuck on this for nearly a week.  Any response is appreciated.
