While we do have an M0062-2, UFS cards are like hens' teeth. Looks like eBay is about the only way to get one; Samsung seems to have stopped making them.
We did notice the SD_UFS_CARD_DET_N signal on J5 pin A12; is it reasonable to assume that we'd need to pull that pin low even if using a UFS chip (rather than a card) in order to signal the presence of the device?
