HI everyone,   Could you please let us know the issue with UART2 and UART3.   IOMUX define as follows: #define MX53_PAD_EMI_D27__UART2_RXD IOMUX_PAD(0x490, 0x148, 2, 0x888, 1, MX53_UART_PAD_CTRL) #define MX53_PAD_EMI_D26__UART2_TXD IOMUX_PAD(0x48C, 0x144, 2, 0x888, 0, MX53_UART_PAD_CTRL)   #define MX53_PAD_EMI_D24__UART3_TXD IOMUX_PAD(0x484, 0x13C, 2, 0x888, 0, MX53_UART_PAD_CTRL) #define MX53_PAD_EMI_D25__UART3_RXD IOMUX_PAD(0x488, 0x140, 2, 0x888, 1, MX53_UART_PAD_CTRL)   tx is ok ,but rx can not receive data.  Please advise us asap. We have stuck since long time.
