自制的 CH565 USB3?板子,芯片沒有寫入任何程序,
接好USB?線插入win10?usb3端口后,設(shè)備管理器提示“未知USB設(shè)備(處于合規(guī)模式的鏈接)”
用MounRiver?配合 WCH-LINK?連接CLK?DIO調(diào)試,工程用的是”CH569EVT\EVT\EXAM\USBSS\USBD\CH372Device“調(diào)試啟動錯誤信息如下:

CH565供電電壓是2.8v,USB供電3.3v都正常,用示波器測量CH565晶振XO引腳顯示 30M正常,用鑷子短接PB15?RST引腳到地后,win10設(shè)備管理器也沒有發(fā)現(xiàn)新設(shè)備,不知道哪里出錯了,請幫忙診斷原因
