TUSB UART BRIDGE

parag mulay

Other Parts Discussed in Thread: TUSB3410, TUSB6250

After some effort I was able to start the USB to UART EVM. The steps that I took are as mentioned below.

1. I program a Renesas chip using this USB to UART bridge and Renesas FDT protocol this goes fine. I disconnect the COM port.

2. Then I start wind mill (software like hyper terminal) and it sees the COM port (USB to UART bridge) but when I try to connect it fails and even hangs the wind mill.

Is the any other thing I have to incorporate that can make the communication smooth when I am shifting from Renesas FDT protocol to WIndmill.

Regards,

Parag

    In order to have a better picture of your TUSB3410 implementation:

    1.- Could you please let me know wich OS are you using?

    2.- Are you using our latest VCP driver?

    3.- Were are you loading FW from? Is it from the host or from the EEPROM?

     

    Regards,

    Ismael

    The problem as I see it is either because you don't have the EEPROM programmed correctly with the firmware or you don't have the right driver installed.

    Here are the steps you need to follow assuming you are programming an EEPROM:

    1. Download the header generator utility. This is used to generate the .bin file for firmware and device descriptors to be burnt in the EEPROM.
    2. With the default Vendor ID and product ID being 341A, what you can do is go to dos prompt, go to the directory where you have the header generator utility installed, then execute “ GOBIN  VCP-3410-FW_Download-EEPROM_serialized”, basically what this does is that it generates a .bin file of the VCP-3410-FW_Download-EEPROM_serialized.CFG (.CFG is the input).

     

    1. Now download the EEPROM burner utility.

     

    1. The PC where the EEPROM programmer software is to be installed must have all other application using the TUSB3210, TUSB3410, TUSB5052, or TUSB6250 devices removed prior to running the installation/setup program for the TI TUSBxxxx EEPROM Programmer.

     

    1. Then run setup.exe in the DISK1 directory which automatically prompts you to install the EEPROM driver installer.

     

    1. Then connect the hardware without the jumper JP2, it will automatically prompt you to install the firmware for the EEPROM, once this is complete, it will again prompt you to install the EEPROM driver. Once you have installed these two, you can burn the .bin file generated earlier using the EEPROM burner utility.

     

    1. Once the EEPROM is burned, disconnect the hardware, replace the jumper and then uninstall the EEPROM burner before you install the VCP software driver.

     

    1. Install the VCP driver and you should be all set. This is all described in the documents on the product folder.

    If you want it use the default VID/PID and not using the EEPROM (loading the firmware off the PC) then you just need to install the VCP driver and it should work well when you plug in the hardware.

    Let me know if you have any concerns.

    why are there no links to EEPROM programmer for TUSB5052? I accidentally erased the EEPROM TUSB5052 how to restore work? Now, the system sees only USB hub. TUSB5052 not appear in device Manager.

    Please tell me how to make configuration TUSB5052 as hub with external power? Found what needs to change a bit BS in the register USBCTL. But how to do it? Sorry if I write is not in the forum thread.

    Hello Vladimir,

        here is the link to the EEPROM programer http://www.ti.com/lit/zip/sllc270

       The USBCTL is located on the addres FFFC, so you need to configure this memory address according the register description and your desired configuration, please review the application notes and user guides to get a better understand of how to program and configure the device.
