when installing the repository (GitHub - myriadrf/LimeSuiteNG) on October 20, 2024, my LimeSDR XTRX is detected and works fine. After updating (GitHub - myriadrf/LimeSuiteNG) the program, my device (LimeSDR XTRx) is not detected. Why does this happen? Can you give a solution to this situation? Here are the parameters when installing the commit on October 20:
root@user:/home/user# limeDevice -f

with the latest LimeSuiteNG installed:
check if the PCIe driver is loaded: “sudo lsmod | grep limepcie”
check if the system log does not have errors from the driver: “sudo dmesg | grep limepcie”
root@user:/home/user# sudo lsmod | grep limepcie
root@user:/home/user# sudo dmesg | grep limepcie
root@user:/home/user#
it seems that the driver is not active.
Did you do a complete rebuild after the update, i.e remove the LimeSuitNG/build directory and make/install it again?
It might be that some CMake variables were cached from the old build, and did not got refreshed for the updated build.
when you run the cmake, log should show:

ok, the limepcie driver is working now, but does not probe the device.
check if the device is seen by the host system: “sudo lspci | grep Xilinx”
Also did you update only the software, or also updated the FPGA gateware since the last time it was working?
If your board is missing this component XTRX not found - #12 by ricardas FPGA gateware update might have affected boot timing, and the device might not be enumerated by the host system reliably.
Yes, this component is missing on my device. Then should I just solder a 0 Ohm resistor (case 0201) or simply short-circuit this resistor to solve the problem?
There is no difference, it’s up to you whether to use 0Ohm resistor, or just short those contacts. It just connects a signal line.
I carefully plugged the contacts of IC21 and reinstalled Ubuntu and the LimeSuiteNG driver, but here’s what happens to me:

I have LimeSDR XTRX connected with an adapter (https://aliexpress.ru/item/1005007181168192.html?spm=a2g2w.orderdetail.0.0.5fbb4aa60B95A2&sku_id=12000039721618500) to the PCIE port of the computer.
send the the full output of “sudo lspci”
Are two green LEDs blinking on the LimeSDR XTRX?

yes two green LEDs are blinking
Hello, is there any solution to this problem?
the device does not show up in the “lspci”, that means problem is not in software.
Blinking LEDs indicate that the board has power and is receiving clock.
Assuming the IC21 connection has been made, it should work.
If the IC21 has not been connected, you can try plugging the board into different PCIe slots, maybe the timing of one of the slots enumeration will be delayed enough until LimeSDR XTRX is ready to be enumerated.
