Hello,

Is there a sample program that supports USB high speed with MSP432E4?
I tried looking for MSP432 SDK, but I did not know whether it corresponds to High Speed.

Regards,
Da

    Hello Da,

    In the latest SDK the High Speed support is available in the DriverLib version but not the TI-RTOS version. The next SDK release will have support across both non-RTOS and TI-RTOS.

    Having said that there is no example for the same as the Launchpad MSP-EXP432E401Y does not have a USB HS PHY on the Launchpad. So only the FS mode is available in the example. Do you have a board already designed with USBHS?

    Thank you for your reply.
    Does the nortos sample code of driverlib support HS? .

    However, the current MSP432 launchpad does not support HS.
    Even if I run nortos sample code on Luanchpad, will not be connected by HS, will it be connected with FS?
    There is no board yet.
    Customers are considering using HS.
    It will be designed if MSP432 adoption is decided.
    Best Regards,
    Da

    Hello Da

    The NORTOS code requires a simple one line change for configuring the USB for High Speed Mode and IO configuration for using the ULPI interface with an external USB PHY.

    The USB High Speed requires an external USB PHY. So if the code change is not done, then the existing examples for RTOS and/or NORTOS shall use the internal USB Full Speed PHY.

    We can help making the changes for USB FS to external USB HS transition for the NO-RTOS code if you wish to evaluate the same right now. However with support coming soon, it may not be too long before you would be able to see support for USB HS in RTOS examples. From a purpose of evaluation the changes between the mode will be kept minimal so that customers can easily change between the two.
