Unable to connect to FPGA device [0,v0.0,0000] [PCIe Squirrel] #203

Closed Creastoff closed 2 years ago

Creastoff commented 2 years ago

I have cloned the most recent version of the following projects and built and running on VS 2022 & Windows 10;

I have included FTD3XX.dll v1.3.0.4 and installed the corresponding x64 Win 10 driver for the device, transforming it from a USB device to a USB controller (VID 0403 PID 601).

There are three buttons on the device, which I don't really know what they actually do; the first seems to disconnect and reconnect the device (reboot?) the second turns a light on when i hold it the third starts a light flashing for a few seconds then stops (I assume this means I have flashed it correctly using a prebuilt binary from the bottom of the page here https://github.com/ufrisk/pcileech-fpga/tree/master/PCIeSquirrel)

I have tried 3 different cables on three different USB/USB-C slots on my host.

Any thoughts or questions?

what does it say if you run pcileech.exe display -min 0x1000 -v -device fpga?

I have just been trying to hook it up to a Ubuntu Virtual Box, doesn't get passed through for some reason. Tried a few different times, ended up reinstalling the driver a couple of times. Gave up and all of a sudden it now gets to the following message when running the command above in Windows (feels like progress):

DEVICE: FPGA: ERROR: Unable to retrieve required Device PCIe ID [4,v4.10,0000]
PCILEECH: Failed to connect to the device.

Closing, unfortunately no detectable fix was applied for the title issue. Will update if I work out the device pcie id issue.

Yeah, if you're able to retrieve the firmware version (v4.10) that means the USB is working, but you don't have a PCIe link hence the 0000 device id.

I'd recommend against running it in a VirtualBox VM. The USB, as you already noticed, is not as stable as you'd want it to be from my experience...

I'm glad you managed to get it to work though, or at least is on the right track. Best wishes with your DMA attacking!

Update: I had the card plugged into a x1 slot, swapped to a x16 slot and have been able to output 0x1000 to console with the above command.

./pcileech.exe display -min 0x1000 -v -device fpga
