nano的USB还没有测试过, 帮顶一下

可以用USB烧录吗？能进入fel模式?

我也试了n种方法，就是不行，一度怀疑是usb接口问题，但用用三块nano验证之后，终于死心了，现在在测试厂家的bsp内核，看能不能搞好

我也是这个情况，调试usb gadget，打印看着挺正常的，但是枚举一点反应也没有，D+D-都是低电平

主线Linux version 4.15.0-rc8-licheepi-nano，还打印了[    1.946160] musb-hdrc: gadget D+ pullup on，就是枚举没有任何消息

连接usb设备后，确认usb接口电压低于3.3，基本连不上；
另外，看我手上的nano板上的usb接口的usbvcc貌似（之所以说貌似是因为，我不确定我手上的原理图是否是最新版）没连，请自行确认电压

PIN67 UVCC是3V3，但是D+D-是低电平

主线linux吧， 就是按这个网站一步一步做的 http://nano.lichee.pro/build_sys/kernel.html

晕哥， bsp linux能给个下载链接吗？

都是一样的问题

17年的，不会吧
