MESA Card 6I25 Firmware and LinuxCNC Configuration

I have finally converted to LinuxCNC and have also installed a Mesa 6I25 PCI-E Card.
Linux is up and running and know I want to install the Mesa Card.
I am running stepper motor's without encoders on a High-Z Machine.

How do I go about flashing the Mesa Card and then apply the settings already discussed in this forum.

And then what is next, Pnc.. Hal etc...

Please be patient I have never used Linux before so I might be slow on the take-up.

The card should have come with firmware installed.
It may be labelled somewhere eg 7i76x2 or g540x2.

If you really have to flash the card - Peter or Andy could advise you...

Pncconf doesn't cover the 6i25, though you could change all the names from 5i25 to 6i25 in the files after...

Just to try it it may be easier to use a mesa sample config (included in linuxcnc) and change it's names to 6i25.
there is less name changes that way.

The default 6I25 mode is to emulate a 5I25 and use 5i25 bitfiles
so its is identical to a 5I25 from a software standpoint.

Other then I assume it uses 6i25 instead of 5i25 in the pin names?

In emulation mode (normal for 6I25s) it is indistinguishable from a 5I25 so its pin names
will be "5i25" as well

Lets for discussion ignore that I'm using a 6I25 and pretend its a 5I25.

When would it be necessary to Flash the card.

That depends on the firmware currently on the card.

Open a terminal window and type:
sudo dmesg -c
halrun
loadrt hostmot2
loadrt hm2_pci
show pin *5i25*
exit
dmesg

The "show pin" displays all the HAL pins created by the firmware on the card.
the "dmesg" should list the allocation of the physical pins on the card.

From that you can work out if the installed firmware has the step genearators that you need.
