有關串口的最高速度
請問大大,Uart3 and Uart4 串口的速度可以設超高115200 嗎 ?如果可以的話,最高可以設多少呢 ? 感謝 ^^ 請問如果要修改Uart3的速度的話,是不是修改
kernel/arch/arm/boot/dts/rk3288.dtsi 裏的
uart_gps: serial@ff1b0000 {
compatible = "rockchip,serial";
reg = <0xff1b0000 0x100>;
interrupts = <GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>;
clock-frequency = <24000000>;
clocks = <&clk_uart3>, <&clk_gates6 11>;
clock-names = "sclk_uart", "pclk_uart";
current-speed = <115200>;
reg-shift = <2>;
reg-io-width = <4>;
dmas = <&pdma1 7>, <&pdma1 8>;#dma-cells = <2>;
pinctrl-names = "default";
pinctrl-0 = <&uart3_xfer &uart3_cts &uart3_rts>;
status = "disabled";
};
把115200 改成230400 或是更高的 1500000 呢 ?
