My customer is thinking about changing Boot-Mode by detection of USB OTG port.
The customer intends to make their proto-board with i.MX6Dual Lite and they intend to use i.MX6U with ‘internal boot-mode’. When they want to update their firmware, they want to USB OTG port into PC Host and firmware update can be done via USB OTG port using serial downloader-mode.
BTW, the USB port is used only for firmware update.
I think that changing boot-mode setting is needed (Internal boot-mode to serial-downloader-mode) by USB OTG attach detection. And some modification to hardware design and SW design will be needed.
Do you have any information on this?
Expertise or any experiences?
