I have been trying to make both GPUs visible to external x86 host via miniSAS connector.
I have been told to upgrade the pcie switch, but I have some questions.
Do I need to flash both switch 1 and switch 2? What configuration should I use? My current setup has configuration 0x40044001 for Switch-1, FW version 01, 08, 0, Build D58.
From NVIDIA DRIVE AGX System High Level Block Diagram, looks like GPUs are connected to Switch-2, however miniSAS ports are connected to Switch-1. The only component between Switch-1 and Switch-2 COM Express. I am wondering however GPU traffic is routed to miniSAS?
Per flashing docs, section ‘Prerequisites for Flashing PM8533 PCIE Switch 2’, it says: “NOTE: Currently this is only supported on internal AURIX firmware.”.
How do I know if we have internal AURIX firmware or not? If not, from where can I get one?
Per docs, after the AURIX setup, ttyUSB15 can access Switch-2, but how do I get it back to access Switch-1?
Thanks a lot for you help!
