[Wizzard]

Thank you very much

[onemanosx]

So, what just happened here?

What does new ioreg shows for i2c device?

[Wizzard]

Will check today, but I think I should give it up. Btw, is it possible to make a touchscreen work at least?

[onemanosx]

is it possible to make a touchscreen work at least?

Similarly, we need to know touchscreen hardware details. I think [ref]erroruser[/ref]'s touchscreen is a USB device? And thats easy to configure.

It is nice to hear that it may work. What should I do to enable it when it does not work? I see there is no dedicated touchscreen thread on the forum.

[erroruser]

some just work same as sd cards as some are an not supported as depending on the manufacture of the devices an not sure if a dsdt ssdt will fix it either

AFAIK, there are no coffee lake support for now.

Ah. That's sad. So no any idea to make it work?

[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

 

DefinitionBlock ("", "SSDT", 2, "ONEM", "i2cc", 0x00000000)
{
   External (_SB_.PCI0.I2C1, DeviceObj)    // (from opcode)

   Scope (\_SB.PCI0.I2C1)
   {
       Name (_STA, Zero)  // _STA: Status
   }

   Scope (\_SB.PCI0.I2C1)
   {
       Device (TPD1)
       {
           Name (_HID, "SYN1B7F")  // _HID: Hardware ID
           Name (SBFG, ResourceTemplate ()
           {
               GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000,
                   "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer, ,
                   )
                   {   // Pin list
                       0x1B00
                   }
           })
           Method (_CRS, 0, Serialized)  // _CRS: Current Resource Settings
           {
               Name (SBFB, ResourceTemplate ()
               {
                   I2cSerialBusV2 (0x002C, ControllerInitiated, 0x00061A80,
                       AddressingMode7Bit, "\\_SB.PCI0.I2C1",
                       0x00, ResourceConsumer, , Exclusive,
                       )
               })
               Return (ConcatenateResTemplate (SBFB, SBFG))
           }
       }
   }
}

[ref]hynrik[/ref], for some unknown reason I am no able to extract your debug files

[hynrik]

@onemanosx I upload the files again. I have two debugs doing two tests

[ref]hynrik[/ref], What is your device id? Use Windows to find out.

More info can be read at first post.

PS: I can see both of your i2c ssdt are not working. Should remove them and find out the device id, first.

[hynrik]

I upload photo.

The device is SBUS

1. Place DSDT.aml in clover/acpi/patched folder.

2. Remove ssdt-TPD1 and/or TPD0.

3. Remove ssdt-xosi.aml.

4. Reboot

5. upload runme folders RunMe

[ref]hynrik[/ref], I am still not seeing your I2C device in ioreg. Are you sure its I2C? Can you reboot with previous settings plus disabled 'change GPI0._STA to XSTA" hot patch too? Then upload new ioreg file.
