Hi dialog，

我最近遇到一个关于DA14580的奇怪启动问题。

我检查我的单板的组件，将它们交换到正常的单板上。但是在更换了电阻、电感、IC等主要元件后，单板没有启动，然后我检查了DA14580附近的电压。正常板VDCDC为1.41V时，buck VDCDC约为0。

正常板VDCDC对地电阻为10 MΩ。将外部1.41V添加到VDCDC几秒钟就可以解决这个问题。自从我将external - anal 1.41V添加到VDCDC解决之后，这个问题就没有再出现过。

你能解释一下问题的原因吗?< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / vdcdc”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > VDCDC < / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords /开始”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >开始< / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:< / div > < divclass="field-items">
