Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

No joke... It's much harder on the board. I have a good solid connection with the chip/clip but its not seeing the ROM. I must be back-powering. Im going to remove everything from the board and then try again later this weekend when I have more time to spare. I was relieved to see an open spot in my case to the chip directly, however after three attempts putting on the clip and the RasPI not reading, I decided not to press my luck...

Only documenting this so others know the struggle. Don't think Ive seen anyone but CaseySJ talk much about the difficulty on board.

Another note... By disabling the SSDT-TB3HP.aml in my EFI I was able to use the eGPU just fine w/ Cinema4D/Octane GPU rendering. No hotplug ability, or the extra goodies of a flashed thunderbolt though... a decent workaround for my needs though until successful flash.
Some additional suggestions:
  • As good as the Pomona is, the cheap run-of-the-mill chip is sometimes more effective.
  • But let's keep working with the Pomona for the time being, as follows:
    • Flip the power switch on PSU to ON, but do not power on the motherboard.
    • Disconnect Vcc (pin 8) from the Pomona.
    • Connect the Pomona clip to Winbond chip.
    • Try reading.
  • If not successful:
    • Flip power switch on PSU back to OFF.
    • Reconnect Vcc (pin 8) to the Pomona.
    • Connect Pomona clip to Winbond chip.
    • Try reading.
    • If not successful, slightly and gently nudge the clip so it makes slightly less contactwith pin 8 on the Winbond chip, but makes good contact with other pins.
      • Yes this means nudging the clip so it's a little diagonal or slanted.
    • On the Designare Z390 we use a visual indication to determine when the "nudge" is just right:
      • The Designare Z390 has a row of LEDs on one side.
      • These LEDs glow bright yellow when Pin 8 on Winbond chip makes full contact (i.e. we are back-powering those LEDs).
      • By nudging the clip so that it makes less contact with Pin 8 on Winbond, those LEDs glow dim red instead of bright yellow.
      • That dim red is our sign that the nudge is correct.
    • We need to do something like that on the Z490 Vision D...
 
Please have a look at Tech Talk --> Thunderbolt in Post 1 of this thread. It has pointers/links to several mini-guides and provides a wealth of information. If you still have unanswered questions, please ask.
Hi Casey,

Thanks for pointing that out, it's really thorough I am now just a bit confused by this warning:

Thunderbolt peripherals that support both USB and Thunderbolt hosts will not work with the flashed GC-Titan Ridge. This is known as USB-C Alt Mode.

Does this mean devices (Docks, Thunderbolt monitors etc.) that allow you to attach both thunderbolt 3 devices AND USB-C devices will not work properly?

Thanks.

Thanks for the tips @CaseySJ I'll give it a shot sometime on Sunday. I bought the cheaper clip as well for raspberry pi, problem I had with it, is it didn't allow for the jumper cables to attach. The jumpers plastic was too thick to fit the 4 pins and would require soldering instead. The spring is much stiffer though. Figured Id just buy the right tool for the job and ante'd up for the Pomona...

This is the clip I purchased from the raspi mini guide on PG 1

After trying to flash a chip on its own again, I think I was trying to be so gentle with everything, I may not have pushed the clip all the way down. I had trouble flashing an individual chip minutes later. Once I pushed the clip all the way to the bottom feet everything worked again. Seems I need it to go all the way down to the solder joints with the clip. Im pretty sure I did not do this as I had problems with the clip jumping off the chip with a simple breeze.

Good question.
  • Some Thunderbolt devices (mainly docks, but can be other device types as well) can connect via either Thunderbolt or USB 3.x.
Confused? Let's look into this a little more...
  • We are familiar with the USB-C physical port. This port supports:
    • Thunderbolt protocol
    • USB 3.x protocol
    • USB 2.x/1.x protocol
    • DisplayPort protocol
  • But not all USB-C ports support all of these protocols.
  • If the USB-C port has a lightning logo next to it, then of course it supports Thunderbolt
    • Thunderbolt, by definition, also supports DisplayPort
    • So a lightning logo means that the USB-C port supports all 4 of the protocols above
  • A USB-C port without a lightning logo can support:
    • USB 3.x
    • USB 2.x/1.x
    • DisplayPort (but only if the manufacturer chooses to support DisplayPort)
With that out of the way...
  • We normally think that a Thunderbolt device connected to a USB-C port will only work if the USB-C port has a lightning logo next to it. And we would normally be right.
  • But with Titan Ridge, Intel provided a new feature that allows a manufacturer to let their Thunderbolt device connect to a USB-C port that does not have a lightning logo.
  • In other words, the Thunderbolt device can masquerade as a normal USB 3.x device and connect to the USB 3.x protocol on a standard USB-C port.
  • This is called USB-C Alt Mode.
My Belkin Thunderbolt 3 Dock Pro, for example, is a Thunderbolt device that supports USB-C Alt Mode. When I connect it to a USB-C port with a lightning logo, it connects over Thunderbolt and operates at the full blistering speed of 40 Gbps (theoretical max).

But when I connect that dock to a standard USB-C port (without lightning logo) it still connects and works, but does so over USB 3.x and operates at whatever max speed that port allows (either 5Gbps, 10Gbps, or 20Gbps for USB 3.2 Gen 2x2). These are much slower speeds, but at least the dock works.

This is actually one of the (only) issues with the Pomona. The cheap clip grips better.

That's really interesting, did not know that thunderbolt devices were supported over regular USB-C ports at USB speeds.

So in this example, after flashing the device, would I lose the ability to connect the Belkin Thunderbolt 3 Dock Pro to a full on thunderbolt port (at full speeds), a USB-C only port (At USB speeds), or both?

Thanks

If we connect the Belkin Thunderbolt 3 Dock Pro to a Thunderbolt port (USB-C with lightning logo), it simply does not work.

But if we connect it to a USB-C port without a lightning logo then voilà -- it identifies itself as a USB 3.2 Hub. Below we can see some of the details, including mapping of the on-board Ethernet port.

We have actually commented out the injection of device-id, but the mini-guide asks Catalina users to un-comment that line because the native device ID 0x15F3 is not supported in Catalina, but it is supported in Big Sur and Monterey. Catalina users have to spoof the device ID back to 0x15F
Thanks for the Hackindrom update which won't affect me then.
Regarding fakePCIID. I guess I'm better off just using the existing method? It's working fine.
 
For the time being we should not use the auto-upgrade feature of HackinDROM. Instead, we can use the “Create EFI” feature of HackinDROM or we can download the EFI zip folder from the mini-guide, rename “config-AMD-GPU.plist” to simply “config.plist” and copy PlatformInfo credentials into it (serial num, system UUID, board serial num, ROM). These should be copied into PlatformInfo —> DataHub tab in OpenCore Configurator.

The Create EFI function in HackinDROM does this automatically. If you visit the HackinDROM mini-guide, you’ll find the usage information for “Create EFI”.

I’ll add this message to the OC 0.7.2 mini-guide soon.
Thanks CaseySJ. You are a star.

You got me out of trouble again. I created a new EFI on both Catalina Disks and both are booting fine again.

Do you have any idea why might be the cause of my Z490 System hanging on the Gigabyte Splash Screen? It always works eventually after one or more Resets/Reboots but never first time every time! Really frustrating for such a great build!

Thanks again for your assistance. This Forum is an absolutely amazing resource for amateurs like myself.

Ok, makes sense, thanks again! I'm gonna be flashing my Titan Ridge v2 controller tomorrow. I'll post an update then, let you know if all my ports work!
