TUSB321AI - i.MX8M plus Controller

Hi Team,

We are planning to use TUSB321AI CC controller from TI in USB1 Since we have a requirement of USB1 with ID Pin.

By default we have configured CC controller as DRP.Is this good to go for initial/uninterrupted flashing ?

Hope you are doing very well.

For i.MX8M Plus ROM/UUU serial downloading, the processor operates as a USB peripheral, and the ROM code does not require or check the USB ID pin.

So, DRP may work, but it is not the best choice for deterministic, uninterrupted initial flashing.

Best regards,

Salas.
