Hi
@CaseySJ,
I'd like to report some findings and questions:
1. I flash the SPI ROM on GC Alpine Ridge ver 2.0 card, I did it successfully following #15307 in Z390 thread. Before the flash, I can't see the card at all in System Information. After flash, I can see it in System Information-Thunderbolt. But when I tried either Blackmagic mini recorder (recorder can be recognized under Thunderbolt but not able to record any thing) or a usbc flash drive or a usbc SD card reader, none of them work;
2. Then I follow #16293 in the Z390 thread to do the DROM magic. First, I tried BUS ID = 0, Slot number = 4 and RP21. Now I can see it under both 'PCI' and 'Thunderbolt', however mini recorder can't be seen; Then I tried BUS ID = 1, Slot number =4, and RP21; Now I can see the recorder under Thunderbolt and PCI but still unable to see the video.
usbc flash and USBC SD card reader still don't work, can't be recognized in the System Information.
I'm using Z490 with RX580, the on-board TB3 works great (I didn't flash the ROM). I plug in the Alpine ridge to the last PCIe slot. Could you give some advices on what steps I can try?
Thanks,
