请问为什么AM335X USB1无法正常加载SMSC95XX？

本帖最后由 一只耳朵怪 于 2018-6-21 14:31 编辑

自己做的板子，USB1连接的是SMSC9512，现在问题是上电过程中可以识别SMSC95XX，鼠标也能亮，但几秒后又断了，请大家帮忙看看是什么原因？
开始应该是加载上了，后面开始出现hub 1-1:1.0: transfer --> -71的时候就挂了。附件里是完整的log信息

smsc9512这块原理是参考树莓派画得，也按照您给的帖子检查了，原理应该是对的。9512上电过程中可以识别，但是几秒后又断开，开始怀疑供电有问题，我把供电部分也都量过，没有异常。是不是软件上漏配什么东西了？

已经解决，9512晶振没有正常工作，换了电容就可以了。现在两个USB口都好用了，但是9512的网口插上网线没反应，这个会是什么问题呀？
