Hello,
I would like to implement the minimum circuitry for USB to be able to download/flash via UUU. This is the only purpose of the USB port in this design.
I have seen the following post: https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8MM-i-MX8MQ-USB2-0-Design-Without-US...
This post uses the USB1_OTG_ID (GPIO1_IO10) pin to configure the IMX8MM as a host or peripheral.
I have no interest in operating the USB as a host. Is it still required to pull-up USB1_OTG_ID (GPIO1_IO10) to +1V8?
If this is possible, are there any device tree changes requried once the system is up and running? Ideally there is no reason for USB to be operating once in the Linux environment.
Thanks,
Chris.
