I will take a look tomorrow and see what pins are there.

Nothing on P2![;) ;)](/media/kunena/emoticons/wink.png)
The BOB has PWM on pin 1 and on/off on pin 17

I seem to be confusing my threads. I was under the impression that this was a simple on/off spindle, but reading back it isn't.
Your BoB on the second connector needs a PWM. Does your current firmware put that on the right pin?

It looks like the bit-file "7i76e_7i76x1_bstechx2d.bit" has a handy PWM on Pin 1 of the expansion connectors.
So, if you use Mesaflash to upload that bitfile to the 7i76E you should then have a pwmgen available to drive the secodary spindle.

But there is also 7i85 connected.
How can I check what BIT file is flashed on the board now?

If you need 7i85 + Generic BoB then you probably need a custom bitfile.
You can't really tell what bitfile is flashed, but you can get a read-out of what is currently in there, and match it to the PINxxxxxx.vhd files.
7i76 + 7i85 seems like an awful lot of IO pins?

That looks like PIN_7I76x1_7i85x1D_51.vhd
Maybe store.mesanet.com/index.php?route=produc...83_88&product_id=122 is the answer?

7I76x1_7i85x_7i85sx1D maybe as I have the 7i85S board
So adding the 7i83 to the cocktail no need of other bit file?

No, sserial add on cards do no require any firmware changes.

OK.
How complicated would it be to write a new bit-file adding P2 with what I need?
