SK-AM62: GPMC interface from AM62x to Cyclone10 FPGA

Hello Manas

Thank yo for the query.

Do you have a block diagram that you could share.

I would request to start with reviewing the Datasheet and TRM with focus o GPMC interface.

Please review the threads related to GPM interface on E2E.

Regard,

Hello Sreenivasa,

I have looked through the e2e forums and there are mentions of GPMC & FPGA interface about the older version of AM processors. Also there are mentions of code samples but no longer accessible.  Don't know what you mean by block diagram. We want to access the Cyclone 10 FPGA through GPMC. The TRM talks about the interface but we want some sample code examples how this is done and basically what are the registers being used and their settings.

Thanks for you support.

Hello Manas

Thank you.

Do you have some thoughts on the development environment including OS that you are planning or would want to use.

Hi Sreenivasa,

we have not tried any register settings yet. We just got the 2 evaluation boards and exploring options. We will be using QNX OS for this work. But it will help if we have the code in linux first just to get familiar and then move to QNX.

Thanks,

Hello Manas

Thank you for the inputs.

I will reassign the thread to the expert to support on the Linux queries.

Hi Manas,

GPMC is not enabled in Processor SDK Linux for AM62x yet, so I am unable to point you the Linux GPMC driver for AM62x.
