AM4372: USB documentation

Shinji Ueda

Part Number: AM4372

Hi champs,

My customer has question about TRM

AM437x ARM Cortex-A9 Processors Technical Reference Manual https://www.ti.com/lit/ug/spruhl7i/spruhl7i.pdf

16.1 Introduction(2537/4161頁）

USB (Universal Serial Bus) provides a low-cost connectivity solution for numerous consumer portable devices by implementing a mechanism for data transfer between USB devices.

：

This document serves to describe the integration of this third-party USB subsystem and should not be considered sufficient for those wishing to modify the existing Linux USB driver(s) or create a new driver to support this controller implementation. For those who do wish to substantially modify the existing Linux USB driver(s), or create new drivers, contact your TI sales representative for more information on how to obtain the third-party IP databook under NDA.

Customer uses uITRON, then she will make USB Driver.

Her quesiton is that she has to have NDA?
What is the third-party IP databook?

Please let me know.

Regards,

Shinji Ueda

Thank you for your reply.

But there is no reply from factory.

Would you please escalate again?

Access to the third-party IP databook requires a 3-way NDA and as such is highly restricted. Please provide more information on the need.

DK-san,

Thank you for your reply.
But, my question is simple.
What is "the third-party IP databook"?

Customer understands that NDA is necessary. But they can not sign a contract unless they know the summary.

Ueda-san,

I'm not sure I understand your question. The "third party IP databook" is just that...a reference that describes the functionality of the 3rd party IP present in the AM437x device. It is not a programming guide if that is what you are asking for.

DK-san,

Sorry, what is 3rd Party IP?
It is necessary for the customer if it is necessary for creating USB Driver.
Or is this a library published only to 3rd Party?
Or is this a documents such as an API that use library prepared inside the ROM?

Regards,
Shinji Ueda
