PIC32 MX370F512L在从睡眠中醒来后随机重置

大家好，我正面临一个奇怪的问题：我的PIC32 MX370F512L在从睡眠中醒来后随机重置。我做了几次测试，简单地改变和跟踪哔哔声。最后，我发现下面的代码部分，我确信重置正在发生。另一方面，RCON响应也是奇怪的，我得到0x000 000 000 e重置后。这意味着空闲，睡眠和BOR同时设置。两周以来，我一直在这个论坛上搜索几个案例，发现一些人面对这个RCON结果，但是没有人知道为什么闲置和睡眠比特被设置在同一时间-在这些意外的重置之后。只有这个随机重置才会导致这个0E RCON结果。所有其他手动重置都提供预期的结果（仅BOR或POR或两者都被设置）..这里有几个设备，这种情况很少发生（而且非常有趣；如果设备休眠超过30分钟，通常会发生这种情况），因此I2C/OLED显示接口似乎有问题。G或睡眠或IDLE的一些问题。您的帮助是非常赞赏，因为我们疯狂两个星期以来，设备在现场，等待更新：

    Hi All,

I am facing an odd issue: My PIC32MX370F512L resets randomly after it wakes up from sleep. I made several tests by simply changing & following beeps. Finally I found below code part where I am sure Reset is happening.

On the other hand RCON response is also strange, I get 0x0000000E after reset. That means IDLE, SLEEP and BOR is set at the same time. I have been searching several cases in this forum since two weeks, found some people faced this RCON result but no one has an idea why IDLE & SLEEP bits are set at the same time - after these unexpected resets. Only this random reset causes this 0E RCON result. All other manual resets provide expected results (just BOR or POR or both are set)..

I have several devices here, this case happen very rarely (and very interesting; it is usually happening if device sleeps more than 30 min..)

As a result it seems like there is an issue on I2C/OLED display interfacing or some problem with SLEEP/IDLE.

Your help is much appreciated as we got crazy since two weeks and devices are on site, waiting for update :S
