Mesa 7i96S MPG encoder on P1

Hello PCW,

A few days ago i flashed my 7i96s with the 7i96sd_inmp1v2.bin file. Flashing was without error.
Since then, the X-axis-homing does not work anymore.
Homing of y-axis and z-axis works fine, as expected.
I would be glad to get your help to solve this issue
Is there a way to get the 7i96s in the state before flashing ?

Tanks a lot

Hello PCW,

I found a solution:
I flashed my 7i96s with the 7i96sd_mpgp1.bi file from the mesa homepage. Now everything works as expected.
My goal is to wire my MPG to P1, I think, this bin-file is for realizing this too.

Thanks a lot

Yeah, sorry about that, made a quick change in the V2 version, and had a typo
that broke 7I96 input 0

EDIT:

Note that the 7i96sd_mpgp1 firmware has a different pinout on P1 and not a close match
to the common wired MPGs. I just fixed and re-uploaded the 7i96sd_inmp1v2 firmware
if that's more appropriate (and the  7i96sd_inmp1v1 firmware was always OK )

Hello PCW,

I hope to get some help from you again.
I tried to make a custom bit file consisting of these two files 7i96s_2pwmd and 7i96sd_mpgp1. 7i96s2pwmd for pwmgen (Stepgen 4-) and 7i96sd_mpgp1 for mpg on P1.
I used the enfinity software, but it doesn't work because of a version conflict.
Do you know which efinty version works with the 7i96s firmware from the homepage ? Thanks a lot

It should work with any version, I have used from 2021.2 to 2024.something

I tried efinity 2025.1.When I try to open the project seveni96s.xml i get the error:

The previous synthesis run has failed. To avoid potential problems or unreliable data, please run it again.

I click O then I get the message:
The family or device maybe invalid. Click OK to proceed with default family and device. Click Cancel to close project and abort.

Then I click OK the next message:
Encounter internal error. Please get help from support team

What does this all mean ? Do I have to choose a family or device first ?
I`m working on xubuntu 24.04

Do you have any suggestions ?
