Hello Emmanuel,
yesterday you reported on the u-boot ICS channel that you saw an incorrect device path for the SD card on your BananaPi M2 (/venHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Usb(0x6,0x0)/HD(Part0,MBRType=01)).
In dp_fill() both mass storage (UCLASS_MASS_STORAGE) and USB hubs (UCLASS_USB_HUB) are mapped to USB devices. Maybe that is what happened to you.
On my Odroid C2 the following devices paths are created:
Installed device path protocols:
/MemoryMapped(0x0,0x7ff9c604,0x7ff9c604)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/MMC(Slot0)/HD(Part0,Sig6fe30000)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/MMC(Slot0)/HD(Part1,Sig6fe30000)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/MMC(Slot0)/HD(Part2,Sig6fe30000)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/MMC(Slot0)/HD(Part3,Sig6fe30000)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/MMC(Slot0)
/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/ /VenHw(dbca4c98-6cb0-694d-0872-819c650cbbb1)
/VenHw(dbca4c98-6cb0-694d-0872-819c650cbbb1)/ VenHw(dbca4c98-6cb0-694d-0872-819c650cbba2)
/VenHw(dbca4c98-6cb0-694d-0872-819c650cbbb1)/ VenHw(dbca4c98-6cb0-694d-0872-819c650cbba2)/VenHw(dbca4c9...
I have an SD card with four partitions.
The entry with partition number 0 should match to the whole disk. So obviously one device path is missing.
eMMC should be reported as eMMC(SlotNumber) where slot number is a number only, e.g. eMMC(1).
SD cards should be reported as SD(SlotNumber), e.g. SD(1).
Partions should be reported as HD(Partition,Type,Signature,Start,Size) or HD(Partition,Type,Signature) (display only) e.g. HD(1,GPT,15E39A00-1DD2-1000-8D7F-00A0C92408FC,0x22,0x271000)
So there seems to be still a lot to be fixed.
Best regards
Heinrich
