FPGA: ERROR: Unable to load FTD3XX.DLL

[helloboiss]

I'm using PCIeScreamer v1 and haven't used for like half a year. Everything was fine back then but now I get this strange error: FPGA: ERROR: Unable to load FTD3XX.DLL [0,v0.0,0000]. Windows also don't detect the PCIeScreamer device with 0x0666.

Also flashed the device with old pre-binaries v3.2 and the new ones. Nothing works. FTD3XX.DLL is in the same map as pcileech.exe. LED is flashing while holding down the button on the PCIeScreamer, so I don't think that flashing is the problem.

Booted-up my pc and changed pcie slots like 100 times. I still have the same PC as when it worked so it is really strange..

you think my device is broken?

have you downloaded the most recent FTD3XX.DLL from ftdichip.com and placed it alongside the other binaries? The version should be 1.3.0.2

There was indeed some problem with my FTDI driver it was a WinUSB instead of FTDIBUS (I think i messsed something up with Zadig) . Now i get the following error:
FPGA: ERROR: Unable to retrieve required Device PCIe ID[1,v3.2,0000].

For me the v3.2 bitstream was stable like half year ago.. Also Windows still can't detect my fpga device.

Now the problem indicates that there is some problem with the PCIe connection to your computer. The USB connection is fine since it detects the bitstream version. The PCIe bus:num is not detected though - which is a clear indication of some PCIe related error.

The PCIeScreamer R01 have known instabilities with regards to this.

If it was stable half a year ago can you please try to add it to the same PCIe slot as last time; also you can test upgrading it to the most recent bitstream I have. It may or may not help you. Unfortunately since the instabilities are related to the hardware itself I'm not really able to fix this in software.

I have tested with the most recent bitstream. Also all bitstream with version 4.x gives me a flashing LED light. I downloaded the pre-builts with version R01.

I'll double check this next week to see if there is an error on my side. Unfortunately chances are that this is related to known hardware issues with the PCIeScreamerR01 which I cannot do anything about.

Tried on a different pc with another motherboard. Still the same results

The unable to load FTD3XX.DLL should have been fixed in the last update. Closing issue.
