Original question:

AM5728: AM5728 DDR on EMIF1 only

AM5728: What do I have to modify for SW when the board only has DDR on EMIF1?

Part Number: AM5728


Hi Expert

My custom AM5728 board has hardware differences compared to the AM5728 EVM, the board which only has DDR on EMIF1. 

What do I have to modify for the DDR on EMIF1 only?

I ask SW to check the this

Does SW have to do other modify?

 

Thanks

    Hi,

    Linking these two threads since they have the same question.

    e2e.ti.com/.../3566758

    First, can you please let us know:

    1. What software base are you using?
    2. What is the DRAM part # you are using on EMIF1?

    In general, you need to use the XLS register configuration tool to determine the EMIF (DDR controller / PHY) and DMM register values. In addition some code bases, such as the Linux SDK, may require that you update the available memory size, as the total available memory on your system may differ than the EVM. u-boot will pass the available memory size to Linux, and I have observed this to be hard-coded (or read from an EEPROM) in the past. Thus, you must change this in software if your total memory size is different than the EVM.

    Best regards,
    Kevin
