标题: RK3328修改串口波特率之后桌面不显示
开发版：ROC-RK3328-CC
默认的串口波特率是1500000，换了几个工具都看不到打印，所以就该了下内核中波特率地方，修改的地方如下：
--- a/arch/arm64/boot/dts/rockchip/rk3328-firefly-core.dtsi
+++ b/arch/arm64/boot/dts/rockchip/rk3328-firefly-core.dtsi
@@ -61,7 +61,7 @@
            rockchip,wake-irq = <0>;
            /* If enable uart uses irq instead of fiq */
            rockchip,irq-mode-enable = <0>;
-             rockchip,baudrate = <1500000>;  /* Only 115200 and 1500000 */
+             rockchip,baudrate = <115200>;  /* Only 115200 and 1500000 */
            interrupts = <GIC_SPI 127 IRQ_TYPE_LEVEL_LOW>;
            status = "okay";
      };
进不了命令行，桌面不显示时，串口最后的打印如下：
[ 9.072606] sdio: host isn't  initialization successfully.
[ 9.078097] failed to power up DHD generic adapter, max retry reached**

麻烦了解的大神帮忙分析一下，谢谢
