at91sam9261 USB超级难题,在线等高手~ 各位,at91sam9261,按照官方原理图,uboot中usb start之后,发生以下错误:(Re)start USB...
USB: scanning bus for devices... ERROR:USB-error: DEVICENOTRESPONDING: Devic
e did not respond to token (IN) or did
not provide a handshake (OUT) (5)

此时,插入u盘的情况是,u盘灯闪了一下,usb start命令后,u盘灯也是闪了一下,然后熄灭~
感谢路过各位大师,指点~在线等~ 应该是硬件布线的问题 atmel的ARM好搞吗 不好高!! 顶下,我也碰到了跟楼主一样的问题。楼主解决了吗? 解决了!
