Please upload the version on the mainboard.

Yes, it is all the time on. It seems like it is not controlled by any pin on the FPGA, it is connected to the power rail.

Is the green LED that is close to the FPGA always on?

I just tried what you told me with a 5v 2.4A adapter and it had no effect, the same problem still occurs.
It seems that it is the SPI memory of the FPGA that may be giving a problem because I do not get any response from the FPGA.
The led next to the BNC connectors does not light up at any time. The only thing that lights up is a green LED that is close to the FPGA indicating that it has power.
What I do? Could you send me the binary firmware to try to load it into the SPI memory?

It may be that the voltage of the USB port is insufficient. Please connect a 5V@2A power adapter to the red connector of the USB cable before connecting the oscilloscope to the computer.
