設(shè)計師找素材的網(wǎng)站網(wǎng)站被禁用如何解決
1、背景介紹
在運行l(wèi)inux應(yīng)用程序的時候，有時會遇到內(nèi)核崩潰異常的情況，此時串口中會打印出內(nèi)核崩潰時的堆棧情況，如下：
當(dāng)出現(xiàn)這個情況后串口就死了，應(yīng)用也停了，此時無法進(jìn)行恢復(fù)。
之前寫過可通過板子watchdog來復(fù)位，實現(xiàn)重啟，Zynq-Linux移植學(xué)習(xí)筆記之44-linux下watchdog示例_zynq watchdog-CSDN博客
下面介紹另一種復(fù)位方法，不需要watchdog也可以。
2、panic機制
從上面的串口異常信息，可以得知這是在內(nèi)核panic函數(shù)中打印出來的，panic函數(shù)位于kernel目錄下的panic.c文件內(nèi)
panic.c具體代碼如下

從代碼中可以看到，當(dāng)內(nèi)核崩潰時其實還有一個panic_timeout機制來讓內(nèi)核重啟
這個panic_timeout是在內(nèi)核編譯選項里面的
于是可以通過修改內(nèi)核配置選項來使能panic_timeout
3、內(nèi)核配置
使用make menuconfig可以在kernel hacking中配置panic timeout
上面設(shè)置panic timeout為15s
編譯內(nèi)核即可
4、驗證
當(dāng)出現(xiàn)內(nèi)核崩潰時，可以看到后面多出了重啟打印信息，如下：
然后zynq就重啟了，完整的日志信息如下：
