RV1126 Debug改普通串口后,系统启动变慢。不知道哪里耗时了

修改如下:
  内核配置中取消:[ ] FIQ Mode Serial Debugger
  设备树中:disable fiq_debugger。
                  
  1. &fiq_debugger {
  2.                 status = "disabled";        //okay改为disabled
  3.         };
复制代码

                   去掉console=ttyFIQ0
                  
  1.         chosen {
  2.                 bootargs = "earlycon=uart8250,mmio32,0xff570000 ro root=PARTLABEL=rootfs rootfstype=ext4 rootwait overlayroot=device:dev=PARTLABEL=userdata,fstype=ext4,mkfs=1 cgroup_enable=memory swapaccount=1 snd_aloop.index=7";

  3. //console=ttyFIQ0
复制代码

                开启UART2
               
  1. &uart2 {
  2.                 dma-names = "tx", "rx";
  3.                 pinctrl-names = "default";
  4.                 pinctrl-0 = <&uart2m1_xfer>;
  5.                 status = "okay";
  6.         };

耗时多长了?,板子上有两盏led 灯,你可以尝试在 uboot kernel rootfs 控制一下这两盏灯看看板子启动在哪里耗时长

我做了一个点亮LED启动脚本,不修改调试串口的时候,从复位到启动9S。修改之后25S左右。

修改之后的启动日志如下

耗时多长了?,板子上有两盏led 灯,你可以尝试在 uboot kernel rootfs 控制一下这两盏灯看看板子启动在哪 ...

我在rcS文件中添加点灯脚本。
  1. #!/bin/sh


  2. # Start all init scripts in /etc/init.d
  3. # executing them in numerical order.
  4. #
  5. `echo 1 > /sys/devices/platform/leds/leds/jmy\:led1/brightness`      #-----   耗时20S

  6. for i in /etc/init.d/S??* ;do

  7.      # Ignore dangling symlinks (if any).
  8.      [ ! -f "$i" ] && continue

  9.      case "$i" in
  10.         *.sh)
  11.             # Source shell script for speed.
  12.             (
  13.                 trap - INT QUIT TSTP
  14.                 set start
  15.                 . $i
  16.             )
  17.             ;;
  18.         *)
  19.             # No sh extension, so fork subprocess.
  20.             $i start
  21.             ;;
  22.     esac
  23. done

  24. `echo 1 > /sys/devices/platform/leds/leds/jmy\:led2/brightness`    #-----   耗时23S
  25. ifconfig eth0 192.168.0.126
  26. route add default gw 192.168.0.1

  27. ./test.sh
