求教F1C100S与合宙PCIE模块通过USB连接原理图应该如何画
各位大佬，有个问题希望大家指教。
我想使用F1C100S中usb直接连接合宙Air724模块，模块如下所示：
我想实现的功能是合宙与F1C100s通过usb在板子上布线直接连接。
我的原理图的usb部分是这么画的
实际做出来是这样的：
我是用的是论坛中大佬提供的支持usb的linux5.2内核的代码，但是发现下载到tf卡启动后，当上电加载内核的时候，反复重启，我想是不是可能跟PE2的接线问题有关（这个PE2我看很多原理图上都连接到usb接口的usb_id上。但是我的板子和合宙模块是直接拉线连接的，没有usb_id)
我在测试的时候，把PE2也尝试了直接接地，但是依旧在加载到内核的时候反复重启。不知道大佬们能不能指导下，应该如何修改。
在此谢过了。
另外，我做好的linux系统直接下载到licheepi nano上没有问题，初步觉得可以排除软件的问题。
还请大家指教，再次谢过

Re: 求教F1C100S与合宙PCIE模块通过USB连接原理图应该如何画
1. 4G模块你用3.3V供电，很容易导致模块在启动时电源电压被拉下去，4G模块启动时瞬时电流比较大，至少要多放几个大的钽电容在模块电源口。4G模块电源最好单独用一个DCDC降压以保证电流供应，。一般我们用4.0V给模块供电，这样即使有降低，也不会低于3.3V
2. 电脑USB口电流不够，4G网卡启动时需要的电流比较大的，这样更容易导致USB的5V电压被拉到4.5V以下。

哇酷小二 说：
F1C 重启吗？
F1C 重启先检查电源问题，这个很重要。
我不开启usb的情况下，就不会重启，每次一使能usb就出现反复重启的情况了。感觉不是电源的问题。

@阿黄
我后来把它改成独立供电了，还是重启。T_T

这里的是启动时候显示的，反复重启，这里我只粘贴了重启一次的代码，后面始终重复。还请大佬们受累帮忙分析下

Re: 求教F1C100S与合宙PCIE模块通过USB连接原理图应该如何画
你的f1c100s芯片上全部电源都上了吗？之前我也遇到相同问题，不开usb一切正常，开了usb芯片不断重启（ https://whycan.com/viewtopic.php?id=7279 ），后来我把芯片的全部电源都弄上就没在出现这个问题。之前图省事觉得3V电源音视频的，不用就不要了，后来补上就OK了
