I'm planning to use UART serial downloader with i.MX6UL.
I understand using USB_OTG port is easier than using UART port.
But, unfortunatlly, my customer's board doesn't have USB_OTG port.
So we have to try UART serial downloader and please advise me.
I know EVK only support USB_OTG serial downloader from following thread.
Is there any reference schematic to use UART serial downloader with i.MX6UL ?
If there are no reference schematic, please tell me following question.
2-1 Which pins do I uset for using UART serial downloader ?
2-2 How to connnect the pins ?
2-3 What register configuration is correct ?
