Hello
Can I use this firmware and driver for 5A-75E8.2 (version 8.2)?

Yes, you can! Use the version 6.0 as board version, it has the same pinout.Hello

I have just joined the LinuxCNC community and as my first experience working with LinuxCNC software, I plan to use an 5A-75E8.2 board and LiteX-CNC.
Therefore, I request users who have worked with this board to share with me a complete example of how to configure their Hal and INI files.
And also guide me on how to get encoder values and create a closed loop system for each axis.
Many thanks

Is the project still alive? No movement for three months(

3 github links on at the start of this topic, 1 was updated 3 weeks ago, 1 a month ago, and on seems nothing changed for 2 years.
forum.linuxcnc.org/27-driver-boards/4442...board?start=0#228191
So it is still alive, although if stuff is working properly, there would be need for changes.

Most of these projects are helped along by others finding an issue or coming up with improvements, suggestions or additions.
If the project is in a solid working state sometimes it won’t “progress”, especially if the developer has it a point that it’s working for them.
Take the mesa firmware code base, going by the code released it doesn’t get updated often but works fine. The most recent updates are to support the change of FPGA brand.
At the end of the day it comes down to users being active in a project, one guy can’t be expected to do everything.

1- When I close the linuxcnc software or press the estop key, the motors start moving.
2- For homing using encoder z pulse, after receiving the z pulse instead of stopping, it makes a strange movement at full speed and then stops.
I posted this problem before but couldn't find a solution for it.
Does anyone have any suggestions for solving these problems?

I made a header board for 5A-75E8.2 and started testing the litexcnc firmware and encountered the following problems.3 github links on at the start of this topic, 1 was updated 3 weeks ago, 1 a month ago, and on seems nothing changed for 2 years.
