RV1126 Debug改普通串口后，系统启动变慢。不知道哪里耗时了

二十八亩地儿

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. 
   
4. //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

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

二十八亩地儿

板蓝根 发表于 2021-12-22 10:52
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. 
   
3. 
   
4. # Start all init scripts in /etc/init.d
   
5. # executing them in numerical order.
   
6. #
   
7. `echo 1 > /sys/devices/platform/leds/leds/jmy\:led1/brightness`      #-----   耗时20S
   
8. 
   
9. for i in /etc/init.d/S??* ;do
   
10. 
    
11.      # Ignore dangling symlinks (if any).
    
12.      [ ! -f "$i" ] && continue
    
13. 
    
14.      case "$i" in
    
15.         *.sh)
    
16.             # Source shell script for speed.
    
17.             (
    
18.                 trap - INT QUIT TSTP
    
19.                 set start
    
20.                 . $i
    
21.             )
    
22.             ;;
    
23.         *)
    
24.             # No sh extension, so fork subprocess.
    
25.             $i start
    
26.             ;;
    
27.     esac
    
28. done
    
29. 
    
30. `echo 1 > /sys/devices/platform/leds/leds/jmy\:led2/brightness`    #-----   耗时23S
    
31. ifconfig eth0 192.168.0.126
    
32. route add default gw 192.168.0.1
    
33. 
    
34. ./test.sh
