TUSB9261: TUSB9261 Boot Loader driver for windows 10 - 64 bit operating system

Part Number: TUSB9261
Other Parts Discussed in Thread: TUSB9260

I am using TUSB9261 chip in one of the custom board. 

I refer sllu125d.pdf for programming the SPI Flash with hex file.

When the board is connected with Windows10-64 bit PC, Device Manager shows TUSB9260 Boot Loader under Other devices list. 

.

But it needs driver for to flash the SPI flash device.

Kindly help me with driver for this TUSB9260 Boot Loader Utility for Winodws 10 - 64 Bit OS.

Thanks & Regards,

Chinnasamy.

  • Hi All,

     I am referring section 2.1 from sllu125d.pdf document. Attached is the image for installing flash burner software. When the software is installed, the driver also getting installed automatically as per the procedure documented in the sllu125d.pdf document.

    But in windows 10 - 64 bit PC, when i installed the flash burner software, i am sure that the driver is not getting installed. because the installed does not ask for any confirmation to install any diver installation as part of driver installation process.

    So i am doubting that the installer may work well in lower version of windows operating system but not in windows 10 - 64 bit Operating system. So if anyone would help me to get driver for windows10 - 64 bit operating system that would be highly appreciated.

    Thanks & Regards,

    Chinnasamy.

  • Hello Chinnasamy,
    Please accept my friend request and I will send you the file.
  • I accepted Michael
  • Hi Michael,
    Thanks for your reply. Already i have the firmware file with me. What i am asking is, when the flash burner software is getting installed, it will install the driver for the TUSB9260 Boot Loader as well ( Refer Figure 2.2 and 2.3 in sllu125d.pdf document).
    When i install the flash burner application software in windows 10 - 64 bit OS, installer did not ask for the steps to install the driver as mentioned in Figure 2.2 and 2.3 in sllu125d.pdf document. So the flash burner software is not allowing to flash the TUSB9261 SPI flash.

    I have both flash burner application software and TUSB926x_Firmware_v1.05.zip. What i am requesting is the driver for the flash burner application software

    Kindly share me the driver.

    Thanks & Regards,
    Chinnasamy.

  • Hi All,
    Can anyone share TUSB926x_Burner Installer for Windows10-64Bit operating system?

    Thanks & Regards,
    Chinnasamy.
  • What version of the flash burner are you using?
  • Hi Michael,

    I am using version 2.10.0 of the flash burner - TUSB926x_Burner_2.10.0 

    Thanks & Regards,

    Chinnasamy.

  • Hello Chinnasamy,

    We tried the installer in Win10 x64 and it works fine without problems, If the driver is not installing fine please try installing it "as administrator" but if you keep getting the same problem you can try installing it manually.

    -Open Device Manager

    -right click on the TUSB9261 instance.

    -Update driver

    -Browse to the folder where you installed the application, the default folder is "C:\Program Files (x86)\Texas Instruments Inc\TUSB926x_Burner"

    -Select and install the driver.

    Regards,

    Roberto

  • Hi Roberto,

    Thanks for the reply roberto.

    I tried the same. But in the default folder "C:\Program Files (x86)\Texas Instruments Inc\TUSB926x_Burner", the driver is not available.

    while installing the TUSB926x_Burner_2.10.0.exe that creates and installs the files in the "C:\Program Files (x86)\Texas Instruments Inc\TUSB926x_Burner" folder.

    Also the installation process should install the driver. But that is not happening in my case. Below sequence is not happening in windows10- 64bit.

    Kindly suggest how to get this driver installation step which will install driver in "C:\Program Files (x86)\Texas Instruments Inc\TUSB926x_Burner" folder..

    Thanks & Regards,

    Chinnasamy.

  • Hi Roberto,
    Also when i tried to installed driver manually by locating the installation folder "C:\Program Files (x86)\Texas Instruments Inc\TUSB926x_Burner" folder, It says that driver is already installed. Attached image for your reference.



    Now i am not sure because i am seeing "Unknown USB Device (Device Descriptor Request Failed)". I could not able to understand whether driver is not available/ there is a hardware issue which is not allowing to detect the Device?


    Thanks & Regards,

    Chinnasamy.

  • If you think it is a hardware issue can you please post the schematic?
  • Dear Michael,

    As requested, i am attaching the schematic for the USB to mSATA interfaace.

    Kindly review and share your feedback on the same.

    Thanks & Regards,

    Chinnasamy.

  • Where is the 10K pull down on the USB_VBUS pin? Also why is there a T connection on USB_CON_N/P that might cause signal integrity issues.

  • Hello Michael,

    We actually missed out this 10K pulled down in the design but later we added it on the board. However this has been already sorted out.

    About T-connection, we wanted to use the same USB connector for programming the TUSB9261 and for normal USB function using OTG. i.e. while programming the TUSB9261, OTG will be disconnected by removing jumpers on P5.

    And we are able to see the device detection in the device manager, but the actual problem is,the driver is not getting installed.

  • the issue is looks like a signal integrity issue or a communication to the host pc issue. Can you send me the layout files?
