My customer is building a custom board with i.MX6UL and they have to fix their schematic by this week.
They plan to use USB_OTG only for serial download.
But there are no detail description in chapter "8.9 Serial Downloader" of RM.
So let me confirm which pins need for USB_OTG serial download.
There are following pins for USB_OTG1.
Which pins do user need only for USB_OTG1 serial download ?
According to the reference schematics (SPF-28617_C1.pdf and SPF-28616_C.pdf), it seems that USB_OTG serial download needs only following pins.
Is it correct ?
If my understanding is correct, what is your recommended connection for unsued pins ?
If my understanding is wrong, which pad do you recommed to use for USB_OTG1_ID, USB_OTG1_OC and USB_OTG1_PWR ?
