7i92 and G540 combination?

I should have asked in advance of ordering; but here i am....
I am currently in the process of finishing a long delayed pet project of finishing my desktop router/mill.
It has been a hassle trying to configure the pncconfig, I don't know what i am doing (stepconfig was a breeze).
The problem i am having is i can't seem to latch the charge pump...
I don't know if it is the correct pin, i am assigning because of the numbering system.. ( confusing!)
The question i am having is wether or not the mesa card can even accept the fixed pinouts of the g540...?
The numbering system of the pncconfig suggests that i can't, as the stepgen pin settings are pretty much already in place...
i was trying to get it going a year or two ago and gave up. The older release didn't even have a setting for the 7i92...
but now i ask; There is a g540x2 preconfig but is there any advantage in using it? i can seem to get my head around it...
Also; I'm hoping to use the second port with a basic BOB from peter homann Do you think that will work either...?
 
Here you can see the configuration i saw fit to construct. It is a 7i92h and so it just relies on 26pin IDC connectors and ribbon cables, I thought it would be brilliant because of the small footprint.

1. Yes, you would use the 7i92_g540x2 firmware for a G540
(this is necessary as it has the stepgens and PWMgen on the
correct pins for a G540 drive)

2. You need to write this firmware to the 7I92 card, something like:
mesaflash --device 7i92 --addr 10.10.10.10 --write 7i92_g540x2d.bit --reload

3. You can verify that the pinout is correct with:
mesaflash --device 7i92 --addr 10.10.10.10 --dbname1 g540 --readhmid

4. The Homann breakout can be used for GPIO with the 7i92_g540x2d.bit configuration
but to use any other features (like stepgens encoders or PWMgens) it would need specific
firmware

Thank you so much for letting that to bare... I probably have been told before but i just doubted it...
I have forgotten where to download the mesaflash software; but it seems that i have a copy flashed already...
 --readhmid  gets a reponse;
 
which is fine, but i don't recognize the pinouts they aren't the last time i used pncconf, they look like the first time i used it...

So the question now becomes how do i set the pins..?
 

i just restarted the system and this came up which is similar to the current settings...
can you tell me if 016 on the pncconfig is the same as (pin16: chargepump)on the readhmid page?
 
 

It looks like you did not select G540 firmware in pncconf
The chargepump is Stepgen 4 on DB25 pin 16 (as the --readhmid pinout  shows)

 

 

currently i am trying to get the pncconf to make a change to the readhmid...
the number of step gens i have selected in pncconf is 5; while the readhmid still persistantly shows 10...
is there perhaps some sort of hard set that i have performed in an earlier session,
do you know of any way in which i could have opted for a hardset...?
I have a vauge memory of such a thing...

so the the readhmid is set to the correct firmware, and shows the correct pins?
I think i need six stepgens there is the chargepump on both BOB's too...
are outputs and analog signals stepgens also?

what do you think i should do next...
I still blind as to why the CP won't latch...

 

Did you setup stepgen4 as a chargepump stepgen?
(as shown in my pncconf screen shot)

A G540 need 4 stepgens for motion, the fifth stepgen (stepgen 4) is used
for driving the chargepump

This means you only need 5 stepgens unless you need more for motion
or charegpump on the second connector.

Note that if the second connector has a different pinout than the G540
(and not just GPIO) you may need different firmware

I have been having trouble logging in(the system locks me out every other time I log-in), hence the delay between posts...sorry.
Yes i now understand that the sixth pin from the top is the pin 16 and that it should be set to charge pump.
It wasn't until i started this thread that i learnt it though(the numbering system was a hurdle i hadn't figured out).
So, what has been happening was i could see, after setting the pin correctly,
was that the fault light would latch on for half a second and latch back.
I thought this was odd so i disabled the charge pump on the g540,
and found i needed to invert the signal to the fault input on pin 15.
This got me some motor movement, and i set the charge pump back to on.
But with the charge-pump re-enabled i got different behaviour.
The f1 key is now fully locked and won't operate.

I get a lot of errors about read and write queue's
and one about a 'something' has "bit" and that i should set a 'setting' to false.

I noticed there is a charge pump setting for both step gen and output,
I have tried both inverted and normal...
