USB OTG mode , PCB can't open USB device

macochen — Wed, 06 Jun 2018 03:20:14 GMT

IMX6DL板子PMIC輸出各點電壓和时序都正確，USB_OTG_ID管脚悬空，BOOT模式选为串行下载，USBOTG连接电脑后，电脑显示有辨識的HID-compliant device，但是NXP DDR Tool 卻顯示 Eorr : Can't open usb device，請問是什麼原因。 ( 備註: USB_OTG_ID 準位 Low，由 CPU 控制介接至 ENET_RX_ER ；查詢資料 USB_OTG_ID 準位因該為 High )@

Hi Maco,

You are using i.MX6DL, but from your screenshot, the CPU you selected is I.MX6DQ !

Change it to be i.MX6DL, please! Then try!

have a nice day!

Best regards,

Weidong Sun
