Hi,
In our design we are planning to use USB3.0 micro-B connector for USB device and we have some question in USB3.0
Please verify the attached snapshot and let us know if any changes are required. We are planning use this for serial down loader purpose
 
1.      ID pin is required for USB3.0 communication?
2.      Only USB1 support for USB3.0 device?
3.      Is this fine if I connect VBUS permanently high through internal 5V?
4.       ROM code supports only USB1 to flash the program by using the down loader mode  as per the section 6.1.8 serial downloader from IMX8MDQLQRM reference manual?
In reference board Type-C and ptn5110 interface used for to flash eMMc chip on this board.Our custom board we are planning with USB 3.0 Micro-B connector .

 

 

Thanks,

Venkatesh
