For added information, here are the snippets from the lua startup script:

    # Step 1 - Start USB device stack
    io-usb-dcd -dusbrndis-am335x-musbmhdrc ioport=0x47401400,irq=18,nodma,force_device_mode,inherit_cfg
    waitfor /dev/io-usb-dcd/io-usb 4
    waitfor /dev/io-usb-dcd/devu-usbrndis-am335x-musbmhdrc.so 4

    # Step 2 - Start USB RNDIS function driver
    # For best performance attach the usbdnet driver to an existing io-pkt stack. Alternatively multiple
    # io-pkt stacks can be used (see SDP documentation for more details). 
    mount -Tio-pkt -o mac=123456789abc,protocol=rndis devnp-usbdnet.so
    ulink_ctrl -l1

    # Step 3 - Assign IP address to ncm interface using DHCP OR any static IP.
    if_up -p rndis0
    
    ifconfig rndis0 192.168.10.100

Again, usbrndis-am335x is a clone of the ndm driver replacing the descriptor header file with the published rndis header
 file. Any help would be appreciated.

Hello QNX Community,

For anyone interested, there is an issue with the argument processing in io-pkt. For RNDIS, both device and host side 
MAC addresses have to be specified in the mount -Tio-pkt command like so:

    ##### Example of RNDIS device (Ethernet over USB) #####
    # Step 1 - Start USB device stack
    io-usb-dcd -dusbrndis-mx6sabrelite-ci ioport=0x02184000,irq=75
    waitfor /dev/io-usb-dcd/io-usb 4
    waitfor /dev/io-usb-dcd/devu-usbrndis-mx6sabrelite-ci.so 4

    # Step 2 - Start USB RNDIS function driver
    # For best performance attach the usbdnet driver to an existing io-pkt stack. Alternatively multiple
    # io-pkt stacks can be used (see SDP documentation for more details). 
    mount -Tio-pkt -o mac=123456789abc,usbdnet_mac=123456789abd,protocol=rndis devnp-usbdnet.so 
    ulink_ctrl -l

Also, note that the MAC address must use a valid OUI, or the network stack will silently ignore the interface.
