[ref]Striker770[/ref], You did not patch your DSDT for working I2C.

This is what I found out for your ACPI table

- IOInterruptSpecifiers is 0x5f (more than 0x2f) you are required to follow steps outlined in post 2

- 0x5f is equivalent to pin 47 (read guide in post 2)

Try boot with attached DSDT. (You may need to rebuild permission and cache upon first boot and reboot again)

That's absolutely correct. It was unpatched. When you asked for files, i patched my DSDT for the same and that caused the delay. But still, it doesn't works. Moreover, the ETPD disappears after this.

[onemanosx]

Have you rebuild cache and repair permissions?

If problem still persist, go to dev site for support. The kexts are still buggy I think. For instance, I am not able to use kexts newer than v2.0.2 in High Sierra or Mojave, and the dev is not able to solve that yet.

I've rebuilded the permissions. But no luck.

I've been using v2.1.4 in HS, Mojave and works like a charm. But this is new Laptop and it's Coffee Lake and i'm unable to make the Trackpad working.

They're not helpful at all. Been there for 3 months. No help yet.

Try these kexts. Use original DSDT or my patched DSDT. I need to see ioreg on both DSDT used.

@onemanosx , can you check my files for proper i2c touchpad ? Works fine but I would like to know your opinion.

Thank in advance.

Works fine but I would like to know your opinion.

My opinion doesnt count LOL I am not even an expert. But your ssdt is doing its magic as expected. Did your write the SSDT-i2c yourself?

[mathewgx]

Yes , after a lot of trials and errors.

I would like to have only the ssdt for i2c without the need for the sta and crs patches on config.plist.

Can you check mine?

[onemanosx]

[ref]Striker770[/ref], I think your issue is with your device support. VoodooI2C do not support your device id. Did you try the modded kexts I had uploaded? Also, what you can try is also to replace the pin from 0x47 to 0x00 from my patched DSDT and return status to 0x0F for device ETPD.

And upload a copy of IOreg for troubleshoot purposes.

Good job on that! I will troubleshoot for mine and see if that will help me get out from being stuck at v2.0.2 kexts.

Edit: Looks like I am stuck at old kexts until the dev does something about it.

Hi, @onemanosx,

Here are my files.

Again, thank you very much!

Didn't work . Maybe I need to remove some kexts from apple on S/L/E

YES. Remove any track pad kexts from S/L/E

Trying to build a static dsdt instead of acpi hotpatch.

All done , except for i2c gpio touchpad.

Can you help building it for me ?

[ref]mathewgx[/ref], Here ya go

[mathewgx]

Working great.

Can I ask fo something more ? If you have the time ..

Could you make a ssdt for i2c touchpad (for acpi hotpatch), based on origin dsdt ?

Thanks again for all your help.

You can re-use your ssdt-I2xx.aml for that.

[mathewgx]

Yes, but I would like to compare it with yours , to see if I did it correctly.

Second reason is that with mine ssdt I still need to use sta and crs patch on clover.

With the dsdt you sent me these doesn't needed anymore.

[onemanosx]

Second reason is that with mine ssdt I still need to use sta and crs patch on clover.

For SSDT to function as an "override" to DSDT, it is required for return zero.

[mathewgx]

So , my ssdt for i2c is done right ?

SSDT-I2CX.aml.zip

[onemanosx]

[ref]mathewgx[/ref], This is the code for my ssdt. I dont need xcrs or xsta in clover.

Let's see if you can recreate yours
