AM6442: GPMC settings in SysConfig do not support 16bit data width

Hello Conor,

Thank you for the query.

I need you to provide some additional information on the use case and the memory type that customer is looking to interface.

The below threads could be used as quick reference.

Hi Sreenivasa,

I'm considering connecting 16bit DDR4. Also the second link below could not be opened.
e2e.ti.com/.../am6441-gpmc-configuration-in-sysconfig

Looking at the first link, there was an answer that AM243xSDK is scheduled to support 16-bit memory in April 2024. When will Sysconfig settings for AM64x 16bit DDR be supported? Also, what do you think about Q2? Since Sysconfig does not support 16bit memory connections, how can I use two **.sysconfig files in one project?

Thanks,

Conor

Hello Conor,

I printed the second thread.

This should help answer some of your questions.

Hello Conor,

You should be able to access the thread now.

Please tell me how to use two **.sysconfig files in one project. Note that ① is required for pin settings and initialization (baud rate, etc.) of other peripherals such as UART, and ② is required for GPMC pin settings.

Based on my quick check, i understand we might not be able to merge or use 2 X sysconfig files.

I will update the thread further in case i have additional inputs.

Hi Sreenivasa,

Thank you for your reply. I understand Question 2. What about Question 1? Please let me know when it will be compatible with 16bit.
Is there any way to resolve Q2 before release 16bit compatible sysconfig?

Thanks,

Conor

What about Question 1?

is there a requirement on the type of memory that you are looking to interface for me to check?

Hi Sreenivasa,

This is DDR4 (MT40A1G16KD-062E) installed in EVM.

Thanks,

Hello Conor, 

Thank you.

I thought we were talking about using 16-nit GPMC interface and i was checking the memory and the configuration to check internally on the feasibility.

Not sure how the DDR4 correlates to the GPMC interface query.
