AM57x RTOS USB virtual UART support

Dear Sir,

Is virtual UART on USB supported in AM57x RTOS PSDK?

Can we support it if it is not ready?

BR, Rich

  • Rich,

    I've moved your thread to the device forum.

  • The RTOS team have been notified. They will respond directly here.
  • We don't have any emulation of UART over USB currently in Processor SDK. Let me check with dev team if there is any plan for this. We have UART ports on the chip with driver already, can you use that?

  • Rich,

    Can you provide some clarification here. Why is there a need to implement a virtual UART in the RTOS environment. Does this have to be done in software or is the customer willing to look at UART2USB bridge based solution.

    For virtual UART over USB, there are 2 options:

    customer can use UART-USB bridge chips like FDTI manufactured FT230X. The advantage is that the end user doesn`t need any details of USB signals or doesn`t need additional software for UART implementation. This is implemented on several of our EVMs and is also done on the AM57xx IDK EVM.

    The other option is to implement the USB device class "Communication Device Class" (CDC). Our LLD drivers only support mass storage class (MSC) USB devices and there is no plan to support CDC class drivers. The customer will need to explore this option by themselves as this is not a mass market requirement so is not on our TO DO list to provide in the SDK.
