TUSB9261: Failed to Load the Firmware

Subramanya 

Which version of Win are you using? Can you please disable Windows Driver Signature Enforcement and see if you are then able to install the driver?

Thanks

David

Hi Subramanya,

Additionally, is this being tested with our EVM, or your own device? What EEPROM is being used?

Thanks,

Ryan

Hi

We are using windows 10 pro.

Hi Ryan 

we are using

SPI flash part number.

AT25DF512C-SSHN-B

hi David

Any update?

Hi,

Did you try to disable Windows Driver Signature Enforcement and see if you are then able to install the driver? 

Thanks

Hi David

Yes i tried with disabling Windows Driver Signature Enforcement, but facing same problem.

Hello Ryan

Any udpate?

Hi Subramanya,

Is this with our EVM or your custom board? What firmware file are you trying to burn onto the TUSB9261? One of the firmware files we provide, or one you modified?

The burner detects the TUSB9261 at least, so given it is not burning, my suspicion is that either the firmware file may not be the correct format, or that the EEPROM being used is not compatible, though my research with the one you named indicates it should be.

Thanks,

Ryan

Hi Ryan

Which part we have to use

In datasheet is cleary say SPI flash

Please specify the memory size of the SPI flash to be used,

Hi David 

Any update. we tried with admin mode also, but same problem

Kindly help to reslove the problems.

Hi Subramanya,

Here is a list of SPI flash devices that have been tested with the TUSB9261. Any SPI flash similar in properties should be good with this device:

By EEPROM, I meant SPI flash. Sorry for any confusion.

Do you have any TUSB9261 schematic? How was this designed, was it based on an EVM or our implementation guide?

Would it be possible to try this on a different OS, such as windows 11 or windows 7, and seeing if the results can be reproduced?

If you could let us know which firmware file it is, we can go into the lab tomorrow and attempt to reproduce the issue on our side, and see if there is an issue there,

Thanks,

Ryan

Hi Ryan

Which firmware we need to flash?

Subramanya

Can you please try the following sequence,

• Right click on the "TUSB9260 Boot Loader"
• Choose to "Update Driver"
• Choose to "Browse my computer for drivers"
• Choose to "Let me pick from a list of available drivers on my computer".
• Choose "Have Disk"
• Choose to copy manufacturer's files from: "C:\Windows\INF"
• If the driver is installed successfully, you should see a "USB Input Device" under "Human Interface Devices"

If not, can you try the Burner SW on a Win 11 machine?

Thanks

David
