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。
&fiq_debugger {
status = "disabled"; //okay改为disabled
};
去掉console=ttyFIQ0
chosen {
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";
//console=ttyFIQ0
开启UART2
&uart2 {
dma-names = "tx", "rx";
pinctrl-names = "default";
pinctrl-0 = <&uart2m1_xfer>;
status = "okay";
}; 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 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
