TMDS64EVM: DDR4 Replacement on Custom AM6442 Board – Driver and Configuration Support

Ravilla Dinesh

Part Number: TMDS64EVM
Other Parts Discussed in Thread: AM6442,

Tool/software:

Hello TI Team,

We are designing a custom board based on the AM6442 processor. In our design, we have replaced the DDR4 (MT40A1G16KD-062E IT:E) part used in the TMDS64EVM with a different DDR4 (MT40A1G16TB-062E IT:F) chip. I would like to know:

  1. Will the existing TI drivers (MCU+ SDK and Linux SDK) support the new DDR4 (MT40A1G16TB-062E IT:F) part?
  2. What steps are required to update the DDR configuration for the new memory?
  3. Can you guide us on using the DDR configuration tool and integrating the output into the SDKs?

Any documentation or examples related to DDR replacement and validation would be greatly appreciated.

Thanks,
Ravilla Dinesh

    Please use the DDR register configuration tool: https://dev.ti.com/sysconfig/?product=Processor_DDR_Config&device=AM64x to configure the DDR controller/PHY for your device.  Instructions on how to use the tool is in the README link in the tool. 

    It looks like the device you chose is very similar to the one on the EVM, so you may not have to make any changes.  Because of this, I would start out with using the config from the SDK to see if you can boot.  If it doesn't work, use the tool to generate a new configuration.
