Dear Specialists,
My customer currently adopts Micro USB Micro-B in their product.
He is considering the transition to Type-C.
I would be grateful if you could advise.
---background
ZYNQ (XC7Z007S) of FPGA is installed for CPU and other function, it isn't built in USB PHY.
Currently, USB3320 of Microchip is used as PHY of FPGA.
USB has 2 ports from FPGA, one is USB 2.0 OTG
The other is USB 2.0 Device.
And I would like to propose the following.
USB OTG: TUSB 1210 (PHY) + TUSB 320 LAI (DRP Cont) + TPS 25910
USB Device: TUSB 1210 (PHY) + TUSB 320 LAI

---questions
1. Is there anything to be aware of when making USB type-C from USB 2.0 OTG? .
2. With Type-C, TUSB 320 LAI (DRP Cont) + TPS 25910 configuration
Is there any problem with USB authentication? .
3. FPGA + USB 3320 is already running in the current model.
If the customer replace FPGA + TUSB 1210 (PHY), will it be necessary to change the FPGA's Software?
If the customer have to make big changes, there is also a desire to change only the latter stage of the PHY.
Because the PHY has already been operated,
(FPGA is built-in CPU (USB controlled by ARM Cortex-A 9 side)
