Part Number: DRA821U
Other Parts Discussed in Thread: DRA821

I couldn’t find the RTOS (or baremetal) example code to USB.

I'd like to refer it to know how each USB registers are called.

Where can I get it?

Thanks and Best regards,

Tsurumoto.

Hi,

We don't have USB support on RTOS or BAREMETAL for DRA821. However, you can refer linux SDK for USB support.

Hi,

Do you have plan to support it also on RTOS in the future?

Which part of Linux code do we have to refer to lean the way to create USB driver on RTOS?

Thanks and Best regards,

Tsurumoto.

We don't have any plan now for RTOS in near future.

Ok, I understood.

How about ”Which part of Linux code do we have to refer to lean the way to create USB driver on RTOS?” ？

Hi Tsurumoto-san,

USBSS --> drivers/usb/cdns3/cdns3-ti.c
USB0 instance driver --> drivers/usb/cdns3/core.c

There will be multiple frameworks beneath the driver as well.
