USB 2.0 HS OTG控制器支持外设或主机模式。 也支持高速USB EHCI主机控制器。 文档 新思USB 2.0 IP主要有两个文档需要参考 《DesignWare Cores USB 2.0 Hi-Speed On-TheGo (OTG) Data book》 《DesignWare Cores USB 2.0 Hi-Speed On-TheGo (OTG) Programming Guide》 前者是描述IP的架构,信号,配置,寄存器...
如下图两个箭头处分别对应的是复位中断,和速度握手完成中断 我们通过中断服务函数中打印时间戳(注意要用非阻塞方式),看到Reset_Intr和High speed之间的时间刚好是50mS(打印的是uS单位),和图中对应 而我们在usb_dev_crtl_sft_discon(0);使能DP上拉时也加一个打印,即上面connect后打印的时间戳和Reset_Intr之间是5...
