ADS1274EVM-PDK: DSP not ready...retrying. And I cannot change the USB device driver from NI-VISA to USBStyx driver.

Part Number: ADS1274EVM-PDK

I met the similar problem when using ads1274EVM-PDK, 

And of course, the USB device was enumenated under NI-VISA USB Devices:

My PC is Windows 10 64 bit.

In C:\Program Files (x86)\ADCPro\drivers directory,

I tried to remove the device driver using "mmb0_driver_install_x64-v2.0.0.0.msi", 

then double click "mmb0_driver_install_x64-v2.0.0.0.msi" to re-install, but the device was still enumenated under NI-VISA USB Devices.

For the second time, I remove the device driver again, and found the USB device was enumenated  "unknown device" under other device in device manager, which was expected. After that, I tried to install the driver manually with "usbstyx.inf" under C:\Program Files (x86)\ADCPro\drivers\usbstyx

But unfortunatedly, system prompt can not install MMBO(NI-VISA), because Windows cannot find device driver

It seems to me that I cannot change the USB device driver from NI-VISA to USBStyx driver. Even though changed another PC (also Windows 10 64 Bit).

BTW, I also have a quick try to attach -5V supply to EVM board. But have no effect.

Could you please give me some suggestions to work the board? Thanks. 

  • Hello Jun,

    Welcome to the TI E2E community.

    There may be an issue with the driver signature.  Please install the plug-in for the ADS1278EVM-PDK-SW, which uses the same drivers.  If this does not work, then I suggest try installing software on a different PC.

  • Thanks Keith. 

    The quick result is, I installed the plug-in ADS1278EVM-PDK-SW, no effect; I also tried other two computers, both Windows 10 64 bit, with digital-signature driver disable. After installed ADCPro and plug-in, the USB device was still enumerated under NI-VISA USB Devices. And the same error in ADCPro software, DSP Not response, trying…….

     

    On the other hand, I tried third-party software "zadig". The USB device driver can be replaced from Winusb(NI-VISA use this USB driver) to libusb-win32 successfully. Then I plugged USB cable again, USB device can be enumerated as "MMB0(NI-VISA)" under "libusb-win32 devices" in device manager, which was different from the expect name "USBStyx" . And, error information was still displayed in ADCPro when I load EVM plug-in. So I quit this try.

    Return to your suggestion: what does that mean "There may be an issue with the driver signature"? I am sure I do disable the digital-signature driver requirement in Windows 10 before install these two software. But it seems like that is not enough.

    Does that mean I can only use pc with Win7 or XP operate system?

    And further, I doubt whether there are some other hardware requirements to make the "DSP Response"?  I found an ADS1298-PDK Q&A in the web, it said the MMB0(DSP?) need to be configured as USB boot mode? 

    I assume my ADS1274-PDK is REV F, do I have to do such configurations? 

  • Hello Jun,

    The drivers for the ADS1274EVM-PDK should be signed.  In this case, you should not need to disable digital-signature in Windows.  I am certain that the ADS1278 has signed drivers, and after I replied to your earlier post, was able to confirm that the ADS1274 also has signed drivers, so this appears not to be the issue.

    Can you send me a picture of each of the boards, MMB0 and ADS1274EVM?  I can then confirm which versions you are using.

    The later versions of the MMB0 have everything pre-configured; you do not need to worry about USB boot mode as this is no longer an option.

    Also, you need to connect an external supply to the MMB0 board using the barrel connector J2; suggested ratings of 2A and 6-7V.  Can you confirm that your external power supply meets these conditions?

    It is possible that your Windows10 PC's are still not properly letting the driver (USBStyx) install.  If this is the case, installation on a Windows7 machine should work.

  • Hello Jun,

    I hope you were able to get the EVM working.  If not, you may want to try using a different USB port on your PC, or a different USB cable.

  • Thanks Keith, and sorry for late reply. It works on a Windows 7 machine.

  • Thanks for the update.
