The config generated by PncConf, edit the .hal file with a text editor (not libreoffice) and omit or delete the line containing DPLL timer, savem start the config again.

If you launch LinuxCNC from the command line, you will get a list as the hardware is discovered
which should help with debugging

The timer issue is possibly that the installed firmware lacks a DPLL timer
(and pncconf always puts DPLL timer boilerplate in the hal file)
You can work around this by deleting (or commenting out) any lines that
mention "dpll" in the hal file

Looks like LinuxCNC detects the board:

Would be great if mesaflash also could detect it.

Will mesaflash recognize the card after LinuxCNC has run?

(I've seen this before with some BIO's that detect the card but for some reason disable the cards memory region)

You need to use sudo with mesaflash when accessing PCI cards

I just tried with and without sudo, I also tried while LinuxCNC is running.
Result is the same all the time:

user@denc:~$ mesaflash --device 5I25
No 5I25 board found
user@denc:~$ sudo mesaflash --device 5I25
[sudo] password for user: 
No 5I25 board found

Do get a warning when not using sudo?

If not, something really basic is broken here.

pcw@pcw-HP-Compaq-Elite-8300-USDT:~$ mesaflash --device 5i25
You need root privileges (or setuid root) to access PCI hardware
No 5I25 board found

What version of mesaflash do you have?
