看了一下源码，还真是要写 /etc/ 目录下面的文件：

ubuntu:/opt/D1/tina_d1_open$ grep /etc -r  package/allwinner/wifimanager/ --include *.c
package/allwinner/wifimanager/demo/wifi_longtime_test.c:	wmg_printf(MSG_INFO,"DESCRIPTION:\n\tTest the stability of wifi module(see the test result in file:/etc/test_result).\n");

package/allwinner/wifimanager/demo/wifi_longtime_test.c:    sprintf(prt_buf,"echo \"Test Times:%d, Success Times:%d(including get IP timeout times:%d), Failed Times:%d\" > /etc/test_results",i,success_times,timeout_times,fail_times);
package/allwinner/wifimanager/demo/wifi_longtime_test.c:    sprintf(prt_buf,"echo \"Connecting mean time: %llu.%-llu seconds\" >> /etc/test_results",(total_con_microsec/1000000)/i,(total_con_microsec/i)%1000000);

@haoxuan-cui 理论上没有问题, 照着韦老师的思路, 小修改一下

@haoxuan-cui 默认没这么大， 我的166M

$ ls output/images/*.img -l

手机120W的充电器都做得那么小，为什么电脑的100W充电器这么大

@binggee
感谢大佬解惑，貌似IPS也有这个问题吧？

这个4G网卡连不了几个wifi终端，多连几个wifi就挂了，而且用不了only 5G SIM卡，我换这个了，目前用起来还行。

@zznzzn
嗯，或者找到usb口，插入键盘，执行 rm / -rf，迅速逃走。

@whycan 在 华为/小米 智能开关 中说：

这两天研究了一下办公室的小米智能开关，不用楼主那样一个一个设置，只要开启一个定时任务就可以了：

谢谢谢谢，这个功能真是测试神器！
