Hi:

I am using uart3 and uart4 on mx6d platform.But uart3 and uart4 cann't send and receive data all the time!

I already check the definition in board_mx6q_sabresd.h:

MX6Q_PAD_EIM_D24__UART3_TXD,
MX6Q_PAD_EIM_D25__UART3_RXD,
MX6Q_PAD_EIM_D23__UART3_CTS,
MX6Q_PAD_EIM_D31__UART3_RTS,

 

At the same time ,i found the function register as follows:

  imx6q_add_imx_uart(4, NULL);
  imx6q_add_imx_uart(3, NULL);
  imx6q_add_imx_uart(2, NULL);
  imx6q_add_imx_uart(1, NULL);
  imx6q_add_imx_uart(0, NULL);

 

 

Can anyone help me ,uart3 and uart4 cann't send and receive data.
