AM62L-PROCESSOR-SDK: Processors forumQuery on Dual-Port RAM (DPRAM) Support in AM62L

Tool/software:

Hi ,

I wanted to confirm whether Dual-Port RAM (DPRAM) or similar functionality is supported on this platform, as we have previously used AM335x with external DPRAM interfaces.

Can you please confirm if AM62L supports interfacing with Dual-Port Memories, and if not, is there any recommended alternative approach for achieving shared memory communication?

Hello Dheeraj K,

The assignee is currently out-of-office.

I need additional time to internally discuss with an expert.

I will come back with an answer in 1 or 2 days.

Kind Regards,

Anastas Yordanov

Hi Dheeraj,

Sorry for the late response. According to the TRM, AM62L supports one channel LPDDDR4 memories. Please let me know if this answers your question.

Regards,

Stan

I assume you connected the dual port ram to the AM335x GPMC interface? If so, the same interface exists on the AM62L. It is an async memory interface, and only supports 16bit Muxed Address/data. If this is what you used on AM335x, then AM62L should also work
