bit3模块wifi一启动就重启

自己做的母版,焊上bit3模块,启动后只要启动网络功能,模块就自动重启。

通过/etc/init.d/network disable 禁用网络后可以进入系统,然后手工启动network又会自动重启,可能是什么原因?

确实是电源模块供电的问题,修改之后目前运行稳定。

@ygxstar 怎么样了?

好的,谢谢。我手上暂时还没有这部分原理图,我让硬件工程师确认一下先。

@ygxstar 3.3V要稳定,wifi加载瞬间可达800mA。
电源部分原理图可以贴到这我检查一下

谢谢。测试发现,有的板子是可以启动的,有的板子wifi一启动就会重启。
我们是自己做的电源模块,这个BIT3对电源输出功率有多大要求?

@ygxstar 供电不足
