Hi,
@CaseySJ,Thank you for your reply
--My GC-Alpine Ridge V2 Card can not be used whether it is nvm20-v1 or nvm20-v2, which shows that there is no equipment under ioreg, and I used the firmware NUC8i7HNKpatched.bin
--TB BUS can appear with this firmware NUC
--I have two Thunderbolt devices, one is LG display and the other is HP Dock. The HP Dock can be normally used and hot-plugged, while the LG display has no black signal screen
--My motherboard is Gigabyte X99 Designare-EX
--THB_C header cable connected to the AR card
I found that all the motherboards that could be used were Z170,Z390, but nvm20-1 and nvm20-2, which could not be used on my motherboard
There is a built-in TB on my motherboard, the model is DSL6540 Alpine Ridge, this is the firmware of this TB, I wonder if I can brush the firmware of this built-in TB to get TB BUS.
