    USB-Serial

    nxsbc15

      We wish to usethe Eval board 43362 based] to our target board based on LPC controller. We have a FTDI-Serial driver in our USB stack. Can we use the same to create the driver as required by BCM9WCD1EVAL1-B. If not, what are the changes we need to make in order to use our FTDI-Serial driver to function a Broadcom USB Serial Port.

          Hi,

           

          Yes you can do the same serial interface to USB similar to BCM943362WCD4. Some information to setup the FTDI chip to relay serial port signals to USB can be found here WICED FTDI chip programming. The FTDI chip on the BCM943362WCD4 EVB interfaces UART and JTAG pins of the MCU to the USB.

            Thank you for the response and appreciate the details. If i understand correctly:

            1. The FTDI chip on the Eval board has to be programmed from the tools mentioned.

            2. Should we change the VID, PID on our USB ftdi driver. The existing values are:

                 #define FTDI_VENDOR_ID  0x0403

                 #define FTDI_PRODUCT_ID 0x6001

             

            Best Regards,

            Girish

              Hi,

               

              When you update the FTDI chip with your setup, you should put your company specific VID and PID to load your own specific drivers.

                Module shows VID = 0x0a5c and PID = 0x43fa in Windows/Linux lsusb

                Our FTDI driver [LPC Host] has VID = 0x0403, 0x6001

                Should we update the FTDI chip or our driver ?
