I'm using LinuxCNC (axis gui), "linuxcnc-stretch-uspace-amd64-r10.iso ".I tried in both ways to reload the card, with the command --reload and completely turn off the PC and turn on it again, but in the end my firmware is always replaced. I'm going to try with another pc now.

Your firmware cannot be "replaced" except if it have a bad CRC in which case the fallback configuration will be loaded
the only way to replace the firmware is to run Mesaflash (Path Pilot has a script that does this on startup )

I understand you perfectly, believe me, but I can't do anything but report the facts that happens to me, don't worry I'm already used to the oddest things that happen to me, I'm bewitched.
I mounted the 6i25 board on another PC and after doing the flash it works perfectly after every turning on. Now I have reported the Bios of the old PC to its default configuration and rermounted the 6i25 card on this last, the card works fine, the firmware is not overwritten (sorry I don't know if it's the right word) anymore but the 6i25 is not always initialized with the PC.
I keep testing, maybe I find something badly set on the BIOS...

Nothing in the BIOS can cause reloading of the firmware image in the EEPROM (only Mesaflash can do that)
If the firmware load from EEPROM is unsuccessful at powerup, you will either have an inaccessible card (no DEVID in lspci) or the card will load its backup configuration (there are only 2 possible configurations in the EEPROM, the normal user configuration and the fallback configuration, the default fallback configuration is recognizable because it blinks the red INIT LED continuously and it has only GPIO )
When you say the card is not initialized properly, what does Mesaflash show?
What do the red LEDs light on the card do?

A- At the beginning before I switched PCs this is what was happening:
1.A Sometime when I started the PC1 a red led turns on on the 6i25 board and doesnt turn off, the PC wouldn't boot.
2.A I start the PC1 an the red led flashes once, the vents get off as if the PC1 had been switched off for 4 seconds ca, then the led flashes again one more time. The PC1 starts but the Mesaflash readhmin chooses the penultimate firmware flashed, not even the default or the last one. ( I realized about this after I wrote you today, I apologize).
**************************************************************************************************************************************************
B- That's when I decided to mount the 6i25 board on another PC (let's call it PC2)
1.B I start the PC2 and flash the 6i25 with my custom bit file again, I don't reboot but turn off the PC2 completely. I turn on the PC2 and control the 6i25 hasn't lost the firmware. All was OK.
Then I access to the BIOS of PC1 and reset it to the defaults.
2.B switch the 6i25 back to PC1, the red led blinks once and the PC1 boots, the board woorks perfectly.
3.B start PC1 again, the red led doesn't flash this time and Mesaflash displays Board not found.
Points 2.B and 3.B happen randomly.

Its not possible for the FPGA to load the previous EEPROM image, so what is more likely is that the
FPGA never reloaded or that the EEPROM write failed
This may be because one PC has a bad 3.3V power supply ( the FPGA will be held in reset if the 3.3V is marginal )

I understand but then how is it possible that I could still use the latest firmware ( the one before I switched the PC1 off)?
,do you advise me not to use PC1?

Good morning Peter.
This morning I turn on the PC and I find it does not start, after a couple of attempts finally I can access to linuxcnc and for my surprise the ...
please forget my previous message, I start all over again, I write all the steps, I want to make sure I'm not making any mistakes, I'm so sorry, I'll report everything here.

I'm using another PC, til now I haven't had any issues with the boot. I remade the custom bit file and ISEL didn't display any errors. Sometimes when I start the PC the board flashes red once, I check the firmware and is always the right one but then LinuxCNC doesn't work properly, the spindler doesn't switch on. I have used the Verify command of Mesaflash, here I attach the result, it says it has an error.
After a while of this happening once again the red led lights for 3 seconds or more, I open the terminal and again the firmware that loads is the penultimate used.
Could you please help me resolve this? I spent two days and I really don't know how to proceed.

There are only 2 EEPROM firmware images on the 6I25, the fallback and the user configuration
it is simply impossible to go back to a previous user firmware version if you have power cycled the board
nor is there any scheme in Linux to automatically update mesa firmware.
It is possible that a firmware update failed or you did not power cycle the machine so the last loaded
image is still in the FPGA ( the FPGA is loaded from the EEPROM at power up )
As I mentioned before there could be a problem with the ATX 3.3V supply (check with a voltmeter) or maybe the 3.3V reset circuit on the 6I25 has a fault. The red lights on the 6I25 should blink briefly _every_ time the power is turned on, if not there is either an issue with the ATX 3.3V power supply or the 6I25 reset circuitry
