PRCM Clock Manager

Hi,

While going through "PRCM Clock Manager Functional Description" in AM35x manual "SPRUGR0",
I found that the actuall explanation about "CM" and the "Figure 4-25. CM Clock Generator Functional"
does not match.
I cross checked OMAP35x's manual "SPRUF98D" for CM, and there it was written correctly,
please let me know which manual is the correct one to refer about "Clock Manager Functional Description".

Thankyou.

    This does look to be the case, it seems the wrong figure was put into the AM35xx manual for the CM clock generator diagram, it looks like it was mixed up with the emulation clocking figure. For the moment for the figure I would reference the OMAP35x figure until the AM35x doc is updated, the devices share a lot in common as the first Cortex A8 parts from TI so the closest figure would be from the OMAP35x TRM. The clock generation scheme on the AM35x should all be handled by the high level OS (i.e. Linux) so I am somewhat curious why you have interest in this low level detail?

    I will file a doc error on this so it will hopefully be fixed in a future release. FYI, you can submit documentation errors and feedback through the 'submit documentation feedback' links at the bottom of each page of the document.

    Sorry, but in our case, we must build an industrial solution and we must start the device from scratch. So we are very interested in this low level detail.

    So, is there some code example (not linux please... ), where we can understand the exact low level initialisation sequence ?

     

    Thanxs for your help
