AM2431: Timer Manager OES RAM location

Nick Capp

Part Number: AM2431

Hi,

I am trying to implement a driver to use the timer manager on the AM2431. In the Timer Manager section of the reference manual there are references to "OES RAM" and "OES Event Lookup Table" but the location of that ram and how it operates cannot be found. Could you please tell me the starting address of the OES RAM and/or point me towards better documentation on that peripheral?

Thanks,

|Nick

Hi Frank,

I am still very interested in using the timer manager. Any luck finding completed documentation?

Hi Nick,

Sorry for the delayed response.

I reassigned this thread a couple of weeks back to someone with more knowledge on this topic. I'll follow up to see why no response.

Hey Nick,

Design came back with the following comments.

The TRM is incorrect and will be updated accordingly.

The Timer Manager in AM64x/AM243x does not support the OES RAM function.

The original OES Event Lookup Table function has been implemented inside the Interrupt Aggregator of the main DMSS.

The Timer Manager generates unmapped events which are routed to the IA which provides steering logic. The event is then routed back to PSILSS to be used as DMA trigger routed back into IA core to generate an SoC interrupt.

Hey Nick,

Release date for TRM containing this updates information is still pending. I would expect these updates to be available by early September timeframe.
