    Thanks for your query.

    In our current MCU+SDK offering USB host mode is not supported. Please refer USB_DEVICE_DRIVER to see what all features are supported.

    Please refer below image.

    Would need to go to AM6442 to get a USB 3.0 host on the A53 Linux core.

    Hi Jim,

    I am not sure whether we have USB 3.0 driver support on Linux. We have USB 2.0 dual role support on AM64x EVM on Linux.

    I am routing this thread to our Linux expert for further comments.

    Please refer USB for more details. 

    Regards,

    Tushar

    Linux supports USB3.0 in host mode. The SK-AM64B EVM has a USB super-speed receptacle. But Linux only runs on AM64x, but not on AM243x.

    Tushar:  

    I see that USB link you mention does not have the SK-AM64B EVM info that Bin just mentioned.  Just saw that is probably part of an open issue referenced on the Linux SDK v10.1 release notes under section  2.1.5.3. Issues Open - "EXT_EP-12071 sdk-doc: missing SK-AM64B information in CDNS3 USB page". Just mentioned that reference to the incoming AM64X marketing manager today.
