5i23/7i52s/7i44- 7i84 startup problem

Hello,
early this year I tried to find a suitable mesa combination for my Deckel FP3A cnc conversion. My first 5i25 7i85S 7i76 7i84 idea got finally replaced by 5I23/7I52S / SPINX1 /7I44- 7I84.
See this post . Thanks again.

So I finally bought:
1x 5I23
1x 7I52S
1x SPINX1 for spindle control
1x 7I44 --> 7I84
Second SPINX and 7I84 will be added, when the complete machine is ready.

A few days ago i managed to get my dc servos working with 7I52S. Using a svst6_6.bit file, which i found posted here, everything seemed fine.

But as soon i tried to get the 7I44 --> 7I84 working, i got in trouble:
Wether the red fault led on 7I84 disapeared starting linuxcnc, nor the green one appeared...
Then i recognized that there are no 7I84 pins at all, doing halrun!
I checked the complete hardware, changed cables, looking into the manuals again and again...
After reading hundreds of posts i found one with a similar problem in this post .

So I got the idea to change the bitfile to SVSS6_8.BIT , disconnected the 5I52S and tested:
halcmd: loadrt hostmot2
halcmd: loadrt hm2_pci config="firmware=hm2/5i23/SVSS6_8.BIT sserial_port_0=00000"
halcmd: show pin
Component Pins:
Owner Type Dir Value Name
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-00
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-00-not
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-01
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-01-not
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-02
5 bit OUT FALSE hm2_5i23.0.7i84.0.0.input-02-not
5 bit OUT FALSE ...

Now my conclusion is: I need a bit- file matching exactly my combination, providing 5 stepgens, 2 PWM gens, 5 encoders and 8 channels for the 7I44, maybee a svst5_2_5_8.BIT file (?).

Has someone the same card combinaton or can someone help me making such a file?

Thanks in advance, hofschmied

Its possible to make a step/encoder/sserial config for the 7I52S and 7I44.

If you have a 7I52S this give you 6 encoder channels and 12 differential outputs
if you have 5 stepgens on the 7I52S, you only have 2 outputs left so if you have
2 PWM channels. neither can have enable or direction outputs on those channels
so somehow this needs to be resolved

Okay, I think I understand now.
So
5I23 FPGA CARD
port 2: 7I52S 4 stepgens 2 PWM gens 6 encoders 2 PWM gens wired to 2X SPINX1
port 3: 7I44 --> 7I84
should be possible. But there has to be a matching bit- file, something like "svst4_2_6_8.BIT" ?

Hi,
I just made some tests with different bit files today, still hoping one could fit. At least now I'm sure I need a custom bit file.
After reading several posts here I finally ended on the xilinx page, so I'm absolutly sure I need help

Sorry for the delay, I will try and get that bitfile made today.

No problem. Thank you for helping me

freeby.mesanet.com/5i23_svstss6_4_8_7i52s.bit should be close

you can use mesaflash to get the pinout:

sudo mesaflash --device 5i23 --readhmid

Green light on 7i84!
Thank you very much PCW!
Seems like the Deckel's new Mesa brain starts working.
