Hi
我们在使用Orin 模组时出了一些状况：GPIO 在意料之外的情况下，输出状态做出了改变。
详细来说：我使用PA.04 PA.07 和PAA.04 三个GPIO 用作控制AVDD DVDD DOVDD 电源输出的使能引脚，这三个GPIO 在系统启动后被我export 并把value 写1，但是经过大概几小时后，在xxx/gpio/export/ 目录下本来已经export 出来的gpio 引脚都消失了，状态回到了未设置的状态。
gpio-352 (PA.04 |(null) ) out hi changed to gpio-352 (PA.04 ）
我们自查了我们的软件程序，确保没有对其进行unexport 的操作。
我的问题是：我该怎么去DEBUG 这个问题，或者有什么办法跟踪显示 GPIO的操作，或者kernel 打印之类的。
去TRM文件上看這幾根pin的register address然後看一下狀況發生前後register有沒有跟著變回之前的狀態
Hi，WayneWWW
谢谢你的答复，这几天我们一直在努力复现这个问题，直到刚才才再一次出现。
根据TRM 手册，我读取了对应GPIO引脚的寄存器。
GPIO_A_ENABLE_CONFIG_04_0： 由初始的0x03 变成了0x00.
GPIO_A_OUTPUT_VALUE_04_0 : 由初始的0x01 变成了 0x00.
GPIO的引脚寄存器确实被重置了。但是我们确认正在运行的软件没有以上行为。
您能给我们提供更多的调试思路吗，谢谢。
請問你碰到的這個問題在NV devkit上能複製到嗎？ 能複製到的話請問要等多久才會看到你碰到的現象？
我认为是能够复制的。
我们产品开发早期就是在NV devkit 上做的，当时就存在无故自动重启的问题，一直没能找到原因，但是由于触发的频率不是特别高，项目需要向前推进，就没有再过分关注这个BUG。
后来随着产品的完善，我们添加了PC端的重连机制，导致这段时间，我们只注意到了Orin 端GPIO 引脚异常的问题，实际上还是由于Orin 端重启导致的。
重启发生的频率大概在一周一次，但分布有的时候比较密集，一天两次，三次。有的时候比较难以复现，好几天都可能不会出现。
我们尝试跟踪了kernel log,但重启时/var/log/syslog/ 并没有记录下来发生了什么，只有类似NULL NULL NULL 这样子的乱码。看起来是没有来得及写入。
所以，对于这种情况，有没有办法获得更多的kernel log 输出，接入uart 串口是不是可以拿到更多的信息呢？
Hi，这次我们似乎抓到了崩溃时的log,看起来似乎于GPU相关。

完整的内核日志见附件，从今天早上9：52开始运行，到下午17:00左右才发生的崩溃。
我们所运行的软件程序大致内容是打开4个摄像头，采集图像，GPU 运算得到结果，关闭摄像头，一次测试中有多次开启，出流，采集，计算，关流的操作，循环往复。以此作为1个循环的话，大概一共跑了280次循环。

建議你還是用uart log看比較準確
syslog在真的panic的時候抓不到.
另外請教一下, 請問這個crash跟gpio有關連嗎？ 如果沒有請你開個新topic.
