PCIeScreamer flashing error - no debug interface found about pcileech-fpga HOT 3 CLOSED

I don't know if this is the error, I'm unfortunately not very knowledgeable about OpenOCD, but I know others had problems with not powering the PCIeScreamer via PCIe or barrel jack. The power that the JTAG flash cable provides alone isn't enough. Power via PCIe should be fine though.

Also make sure you flash the PCILeech bitstream, I don't know if this is the case, but if you flash the LambdaConcept bitstream it will blink the LEDs on the PCIeScreamer.

After a flash the board have to be power cycled for the changes to take effect.

Thanks for the advice, @ufrisk! Just an update, I managed to overcome those problems by rebuilding openocd with an appended --enable ftdi to the ./configure command and installing lib-usb dependencies. I also updated the openocd rules file to /etc/udev/rules.d in Linux. I'm now facing the output below:

More than 128 errors, the rest are not printed

Does this mean that the device is not properly flashed with the pcileech bitstream? When I tried to run a pcileech probe command, an error occurs to state that there is no device found. Is this due to the warning in which the card has not implemented paging?

For now, it only seems that LD3 is lit up, and pressing SW3 has no effect.

LD2, which indicates PCIe link activity is not lit up. Is the flashing unsuccessful because of this? I've checked using lspci with linux and the device manager but am unable to see a Xilinx ethernet adapter (according to other issues posted).

Edit: I've tried reseating the pciescreamer card into other x1 slots and another x16 slot. Still no sign of LD2. I've also tried to update my BIOS to the latest version but still the issue occurs. I've checked the power pins to make sure it's configured to PCIe and the SW2 switches are on, off, off. Virtualization features are also disabled in the BIOS.

Just an update, I managed to flash the card but i'm still unable to read the memory of the machine.

The updated lambdaconcept instructions at http://blog.lambdaconcept.com/doku.php?id=products:jtagserial_programmer#spi_flash_programming have shown that you can apply a git patch to resolve the contents differ problem. This might be useful for anyone facing this problem. I still faced errors erasing the flash and I only managed to flash it with the Xilinx programming cable.

I'm now facing a similar issue to the errors shown at https://github.com/ufrisk/pcileech-fpga/issues/4 https://github.com/ufrisk/pcileech/issues/31.

From the card, LD2 and LD3 are lit up when powered on. LD1 lights up when I press SW3 too.

Any ideas what is wrong and how do i fix it?

I've tried verifying the flash contents using Vivado. l've ensured that anything inhibiting DMA is not on e.g. virtualization and SGX?.

Also: The LEDs are not reliably lighting up and I need to power cycle and press SW1 at times to see if LD3 lights up and if LD2 lights up when booting up.
