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

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。

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

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
