Mentor USB OTG controller (musbmhdrc) documentation

MWagner

I'm looking for a reference document for the Mentor USB OTG controller (musbmhdrc).

I'm interested in a detailed description of the registers and operation of individual bits in the registers.

The AM335x ARM Cortex-A8 Microprocessors (MPUs) Technical Reference Manual (Rev. C) (spruh73c) provides some of this information but does not have complete detail of the available registers.

Please check the updated Rev E TRM for the register definitions that you are interested in (http://www.ti.com/sc/docs/psheets/abstract/apps/spruh73e.htm).

If this document does not contain what you are looking for, please be more specific on what registers you need.

hello,

are there any news in this ?

i've read most current technical reference manual (spruh73i), there are still not all registers of the musb core documentet. u-boot accesses registers which i cannot find within manual.

actually i've the problem, that usb initialization hangs on a specific register - but i cannot look into the manual whats the meaning of this register.

best regards,

hannes

Access to the Mentor register set beyond what is documented in the TRM is not publicly available as it requires a special NDA with the IP owner.

If your company is interested in pursuing this, we can put you on that path.
