5I24-25-ROHs board firmware flash

Hi everyone,
Im very new to linux cnc and i've "5i24-25-rohs & 7i48 daughter board".
First of all i tried to flash 5i24_16_svst8_4im2.bit file to pci card. My effort to flash was successful in the first time. But then i run the code " sudo mesaflash - - device 5i24 - - readhmid". I couldnt get information by it. Then i tried it agaib by restariting my pc. After restarit i got a message " no 5i24 board found". I tried so many times to flash another firmware. But i couldnt do it. Always end up with "no 5i24 board found"
Please help me to pass this step.

Yes, this is somewhat expected since you flashed a 5I24-25 card with firmware for a
5i24-16 and corrupted one of the flash chips.

To recover, power down and open the computer case and perhaps move the 5I24
card so you have access to the card. Move Jumper W7 to the DOWN position and
power up the computer, The red/yellow lights should blink and go out. Now the card
should be accessible. Now without powering down the computer, move jumper W7 to
the UP position. You should be able to run mesaflash again.

You could just move Jumper W7 down, cycle the power and try again but if you make a
mistake at this point you would corrupt the backup flash chip and there would be no
way to recover except sending the card back.

5i24_25_sv12im_2x7i48.bit is the suggested bit file for a 5I24-25 with 1 or 2 7I48s

Thank you very much for your help. I will try as you said.

I just tried as you said. But the result is same. When the jumper in down position red and yellow LEDs are lightup all the time. No change even the jumper set to up position. Is there any possibility to recover the memory?

Did you power down then up with W7 down?

Yes, i did.

OK then the card needs to be returned...

Hello pcw,
I got another brand new 5i24-25 mesa card, so is there any procedure i should have to follow before flash 5i24_25_sv12im_2x7i48.bit firmware? (like fb25.bit or somethingl

I would return the first card for analysis before swapping cards, There is no reason a wrong bitfile should affect the other flash chip so Its not clear whats going on.

I flashed the above firmware and it was successful. Thank you for your help.
