[SOLVED] PCILEECH: Failed to connect to the device

[gcakir]

Greetings,

I installed PCIeScreamer into the target computer. After I boot into Windows 10:
Led2 is blinking continuosly (green),
Led1 is off,
Led3 is on (green).

There is another led (which is RED) on the left-hand side and it is constantly on in red color.

I receive the following error when I input "pcileech probe":
PCILEECH: Failed to connect to the device.

When I input "pcileech display -v", I get "PCILEECH: Failed to connect to the device." error again.

• I tried these inputs both on the target and on the computer to which the USB cable is connected. I always get these errors.
• I changed PCIe slot. It didn't help.
• I tried different USB cables (both 3.0 Micro and Mini 5) which came along with PCIeScreamer, still the same error.

My motherboard is Gigabyte Z390 Aorus Master. I also updated my motherboard's BIOS. It didn't help.

Is it somehow incompatible with my motherboard? What am I doing wrong here?

Thank you very much in advance!

Hi,

Have you flashed the correct PCILeech FPGA bitstream as described on https://github.com/ufrisk/pcileech-fpga/tree/master/pciescreamer

The continuous blinking suggests that you may have the LambdaConcent bistream flashed - which is incompatible with PCILeech. Once you think you have it correctly flashed try press the test button described on the above info page to see if a Led then blinks.

Thank you very much @ufrisk.
I was so excited when I first received the board, I didn't even properly read the description. I hadn't flashed it before I tried using it. I am sorry! I was stupid.

However, I have now another problem. When I am flashing, I receive the following error:

device needs paging or 4-byte addresses - not implemented
contents differ

I receive that error even tough I applied the git patch into OpenOCD as described in this link: http://blog.lambdaconcept.com/doku.php?id=products:jtagserial_programmer

I am sure that the patch has been successfully applied because I can see the changes in the source file. After applying the patch I used following commands to compile OpenOCD as described in the link:

make
sudo make install

I am sure I did everything according to your your descriptions and the descriptions in LambdaConcept's Wiki.

Another important thing I should mention:
In your readme.md it says:

Please also note that the DIP-switch SW2 should be configured as: 1: ON, 2: OFF, 3: OFF.

But on my board there is no DIP-switch SW2. Here is a picture of my board:

The picture on LambdaConcept's website also does not show any DIP-switch SW2.

Could this also be a reason for the problem? Or should this be any cause of concern?

@ufrisk
OK. I solved the issue.
I purchased an JTAG-HS2 cable and flashed it with Vivado Tcl Shell.
It flashed successfully!

The PCIeScreamer was always installed into PCIe X1 slot and I still could not connect the target computer from another computer.

This time, I moved PCIeScreamer to X16 slot and it worked!
