Branched to a new discussion

I am trying to configure UART4. I have added

MX6SL_PAD_KEY_ROW6__UART4_TXD

and

MX6SL_PAD_KEY_COL6__UART4_RXD

in mx6sl_brd_pads[ ].

 

Above pin configs are defined as

#define MX6SL_PAD_KEY_ROW6__UART4_TXD                                         \

        IOMUX_PAD(0x04AC, 0x01A4, 1, 0x0000, 0, MX6SL_UART_PAD_CTRL)

      

#define MX6SL_PAD_KEY_COL6__UART4_RXD                                         \

        IOMUX_PAD(0x048C, 0x0184, 1, 0x0814, 2, MX6SL_UART_PAD_CTRL)

 

I crosschecked these configs and looks like these configs are correct..

 

I have also called "imx6sl_add_imx_uart(3,NULL)" from function mx6_evk_init()

 

I configured UART5 just same as UART4. UART5 works well where as UART4 sends data correctly however could not receive it.

 

Would you please provide me pointers to solve this problem.
