Linux/AM5708: AM570x support in SDK

Adam Lee5

Part Number: AM5708
Other Parts Discussed in Thread: AM5728, AM5718, , AM5706

Tool/software: Linux

I am bringing up a custom AM5708 board. In the linux kernel, I see AM5718 and AM5728 support, but nothing on AM5708.

There are DRA74X support (such as device tree structure).

Can I base my DTS on DRA74X?

    Adam,
    you may be using an old version of processor SDK. Please check this page, AM5706/8 is supported. software-dl.ti.com/.../index_FDS.html

    Which DTS should I start with? I see numerous am57xx, am571x, am572x device tree structures in the new SDK. I just don't see any references to am570x (or am5708 for that matter).

    I also noticed this post hinting AM5708 is based on DRA7. However, I see dra72x and dra74x in the device tree folder. Which one is AM5708..?

    Adam,

    We recommend starting from the AM571x-idk.dts for AM570x development.

    Thanks, I will take a look at AM571x-idk.dts. I checked out your link, and noticed ".dmm_lisa_map_3 = 0x80640100,". I have used the Excel EMIF Spreadsheet and got ".dmm_lisa_map_3 = 0xFF020100,". Which one should I trust? Again, I am using AM5708.

    Use the values from the spreadsheet as long as you are using the latest version.
