Solved: Bitfile needed for 6i25 + 7i77 + Chinese BoB was created by GDTH
Hello Everyone,
I’m looking for a bitfile for my 6i25 setup with a 7i77 (P3) and a Chinese breakout board (P2).
The breakout board will only be used for stepper control.Does anyone already have a suitable bitfile available, or would be willing to help create one? I’m not yet familiar with making custom bitfiles myself and wouldn’t know where to start, so any help would be greatly appreciated.Thanks in advance!

Thanks! i got it running. i was able control the pins. Weirldy enough i was not able to get the stepgen running. i was not able to see anything on the oscilloscope. i did not plug the 12/24v as i thought it is not needed. I was able to pull both the dir and pulse pin high by inverting it.
Any tips are appreciated, gonna continue working on it tommorow

You will likely need to either merge some parts from a standard step/dir hal/ini file setup,
or use either pncconf's discovery option or MesaCT to create a working 7I77 + step/dir setup.

I got it running! Turns out it was just a hardware issue. I’m using a 48V PSU that I hadn’t earthed, which caused some strange behaviour. I’m also running a Leadshine DM805-AI and realized the 5V needed to be connected (I had assumed signal GND).Just in case it helps anyone else, I’ve attached my HAL and INI files.Now making this into a carousel setup—wish me luck!
