RE: Road Testing The FTDI Vinculo (VNC2) USB Development Board

Interesting and informative report on the product.

I would like to try to assist in some of your issues:

I can confirm FTDI have settled on "Vinco" as the product name and the part number is VNCLO-MB1A.

The VNCLO USB port 2 requires IOBUS22 (pin 41) to be set to logic 0 via a GPIO setting to allow for power to be sent to CN2 and power external USB devices on that connector.

Some code that might help is:

////////////////////////////////////////////////////////////////////////
// Vinco....Reassign pins for USB port LED and Power Control (port E used)
// Pin 40 is connected to LED and Pin 41 is Power Enable on Vinco

//vos_iomux_define_input(40,IOMUX_IN_UART_RXD); // Vinco - commented out UART Rx
vos_iomux_define_output(40,IOMUX_OUT_GPIO_PORT_E_5); // Vinco - USB port 2 LED

//vos_iomux_define_output(41,IOMUX_OUT_UART_RTS_N); // Vinco - commented out UART RTS#
vos_iomux_define_output(41,IOMUX_OUT_GPIO_PORT_E_6); // Vinco - Power control

        // Note that LED0..LED3 which are used in the code below are not present
        // on the Vinco board
        ////////////////////////////////////////////////////////////////////////

////////////////////////////////////////////////////////////////////////
    // Vinco....Initialise Port E to control power transistor and LED
    gpioCtx.port_identifier = GPIO_PORT_E;     // Vinco
    gpio_init(VOS_DEV_GPIO_E,&gpioCtx);        // Vinco
    ////////////////////////////////////////////////////////////////////////

////////////////////////////////////////////////////////////////////////
    // Vinco....Set port E bits
    // LED is on E5 and Power Enable is on E6 so 8 port bits are as follows
    // Bit 7        Not used
    // Bit 6        Power Enable (active low)
    // Bit 5        LED (active low)
    // Bit 4        Not used
    // Bit 3        Not used
    // Bit 2        Not used
    // Bit 1        Not used
    // Bit 0        Not used

hGpioE = vos_dev_open(VOS_DEV_GPIO_E); // Vinco - Handle = port E

    gpio_iocb.ioctl_code = VOS_IOCTL_GPIO_SET_MASK; // Vinco
    gpio_iocb.value = 0x60;    // Vinco - 01100000   set bits 6 and 5 as output
    vos_dev_ioctl(hGpioE, &gpio_iocb);            // Vinco

    leds = 0x00;                     // Vinco
    vos_dev_write(hGpioE,&leds,1,NULL);        // Vinco - Write data of 00000000 to port
    ////////////////////////////////////////////////////////////////////////

Additional Vinco examples are expected to be released soon.
