我用PSOC4 BLE（CyBL4248LQI-5853）构建了100块板，我发现其中很大一部分有一个问题，它们周期性地重置自己。有些重置通常是每隔几秒钟，而另一些则重置得不那么频繁。复位间隔看起来有点随机，但很难说清楚。我有点不明白为什么我要找一些头脑风暴的帮助。下面是一些额外的细节。有什么想法吗？
我已经对电路板进行了大量的探索，并没有发现任何错误的复位线或电压供应或任何其他任何单位。我有一个32千赫兹的晶体振荡器和一个24MHz的晶体在板上，虽然我使用内置的RC振荡器（IMO）来产生SysCLK，因为我还没有找到一种方法来使用24 MHz晶体运行我的系统在48兆赫。名义上，我有5V的设备，但实际上，它是4.85伏。 我怀疑这与WDT有关，我不完全理解WDT。我有一个带有ISR的WDT，它正在得到服务。我确定WDT ISR是最优先考虑的。 以上来自于百度翻译 以下为原文 I have built 100 boards using a PSoC4 BLE (CYBLE4248LQI-583) and I'm discovering that a significant percentage of them have a problem wherein they reset themselves periodically. Some reset as often as every few seconds and others reset much less frequently. The reset interval appears to be somewhat random, but it's hard to tell. I'm somewhat stumped on why this is so I'm looking for some brainstorming help. Below are some additional details. Any ideas? I've done alot of probing on the boards and can't see anything wrong with the reset line or voltage supplies or anything else in any of the units. I have a 32kHz crystal oscillator and a 24MHz crystal on the board, though I'm using the built-in RC oscillator (IMO) to generate the SysClk because I haven't figured out a way to use the 24 MHz crystal to run my system at 48 MHz. Nominally, I have the device set for 5V though in actuality, it's getting 4.85V. I have a suspicion that this has something to do with the WDT, which I admittedly don't fully understand. I have a WDT with an ISR, which is getting serviced. I made sure that the WDT ISR is top priority.

请您发布完整的项目或缩短的版本，以显示错误，以便我们都可以查看您的所有设置。为此，使用
创建者-gt；文件& gt；创建工作区束（最小） 并附加生成的文件。 鲍勃 以上来自于百度翻译 以下为原文 Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use Creator->File->Create Workspace Bundle (minimal) and attach the resulting file. Bob |

ncmza 发表于 2018-11-1 16:00 这个项目是相当大的，我不希望任何人分析整个事情。而且，这个问题只发生在我编程的设备的1/3左右。 我只是在寻找一些能引起设备重置的东西。 以上来自于百度翻译 以下为原文 The project is pretty large and I wouldn't expect anyone to parse through the whole thing. Also, this problem only occurs in about 1/3 of the devices I've programmed. I'm just looking for some brainstorming of things that can cause a device reset. |

因此，我发现有一个闪存检测寄存器，看来这些设备正遭受灯灭。然后我注意到，在我的板上的VCCD旁路电容被标记为“不安装”意外。所以没有一个电路板在VCCD上有一个旁路电容器。
我在那个插槽里安装了0.1uF的帽子，因为这是我周围最靠近的东西，看起来它有很大的改进。所以，我想我发现了我的问题。 以上来自于百度翻译 以下为原文 So I discovered that there is a brownout detection register and it appears that the devices are suffering from brownouts. I then noticed that the Vccd bypass capacitor on my boards got marked as "do not install" by accident. So none of the boards have a bypass capacitor on Vccd. I installed a 0.1uF cap in that slot because that's the closest thing I had lying around and it looks like it makes a big improvement. So, I think I've found my problem. |
