Gigabyte MP30AR0 - UEFI MMC



Hey All,

I asked some questions about this a couple of years back but never got it resolved. Taking another shot at getting to the bottom of it.

My situation with the MP30AR0 is that when booting from u-boot I only get one 10Gbe nic but the sdcard (mmc) is available. If I chainload the Tianocore uefi from u-boot (I've never flashed uefi directly on this board) I get both 10Gbe nics but the sdcard/mmc is no longer available.

I'm trying to make it so all four sata ports can be used for data and boot the os from sdcard. I can boot from nfs/usb but would like to get the sdcard working.

I have had no success with_any_ pcie cards so can't currently go down that route.

I've tried tweaking the original device tree and booting from u-boot but either get a failed boot or no change in what is available. I've no idea yet how to go about messing with uefi to maybe reverse engineer that and see what gives. Using binwalk doesn't appear to show any dtb but I guess it uses acpi.

Has anybody with this board got both 10Gbe nics _and_ the sdcard available? Anybody got pointers as to where to start with the uefi blob? Why does uefi see the second nic? Anybody had success with pcie cards?

I'm currently using the latest mainline kernel but I've tried many along the way.

Any pointers thoughts appreciated.

Cheers,
