Hello @etc,Hi everyone!
I'm trying to enable TB Bus on GC-TITAN RIDGE 2.0. I used a modified (5v to 3.3v) CH341a programmer to flash and used GC-Titan-Ridge-V2.0-Mod-NVM50-CaseySJ.bin as a custom firmware. Before flashing compared the original NVM50 firmware with a modified one and have found only few differences, so the choice was right I think.
But with a modified firmware GC-TITAN RIDGE doesn't work at all. No output to LG UltraFine display at all (during boot either), macOS does not detect it: no PCI devices (including Hackintool and IORegistryExplorer), no hardware found in Thunderbolt section instead of 'No drivers were loaded', it just disappears completely. Have the same situation in Windows.
My MB is ASUS Z490-E Strix, so the TB_HEADER is not compatible with TITAN RIDGE. I tried to connect pins in THB_C together, but it did not help.
If I flash an original firmware back it starts working as before, without TB Bus.
I also have ThunderboltEX 3-TR AIC, which is compatible with ASUS MB and works much better. But there's no modified FW for it. Maybe someone could help with it?
Original firmwares I've read from GC-TITAN RIDGE 2.0 and ThunderboltEX 3-TR attached.
Attached zip contains two modified versions of firmware for the two cards:
