please help me.

......

iomux_v3_cfg_t const uart5_pads[] = {
MX6_PAD_KEY_COL1__UART5_TX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
MX6_PAD_KEY_ROW1__UART5_RX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
};

Hi honglei

one can check console kernel parameter described in sect.5.4.2 Kernel command line (bootargs)

attached Android User Guide. In uboot one can check #define CONFIG_MXC_UART_BASE,

#define CONFIG_CONSOLE_DEV in uboot/include/configs/mx6sabresd.h

Best regards
igor
