这是地址,已经配置在A核linux使用了,uart3作为485,uart1作为蓝牙有接流控
uart3: serial@30880000 {
compatible = "fsl,imx8mp-uart", "fsl,imx6q-uart";
reg = <0x30880000 0x10000>;
interrupts = <GIC_SPI 28 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MP_CLK_UART3_ROOT>,
<&clk IMX8MP_CLK_UART3_ROOT>;
clock-names = "ipg", "per";
dmas = <&sdma1 26 4 0>, <&sdma1 27 4 0>;
dma-names = "rx", "tx";
status = "disabled";
};
uart1: serial@30860000 {
compatible = "fsl,imx8mp-uart", "fsl,imx6q-uart";
reg = <0x30860000 0x10000>;
interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MP_CLK_UART1_ROOT>,
<&clk IMX8MP_CLK_UART1_ROOT>;
clock-names = "ipg", "per";
dmas = <&sdma1 22 4 0>, <&sdma1 23 4 0>;
dma-names = "rx", "tx";
