Access UFS When Booting Debian From SD Card



I have a HiKey960 and am currently booting Debian 4.15 from an SD card. I am interested in mounting the onboard UFS as a block device. At boot I receive the following console output:

Is there a way to mount the UFS as a block device?

Thank You.


@TEST you should be able to see UFS as a block device as follows:

root@linaro-developer:~# fdisk -l /dev/sdd
GPT PMBR size mismatch (7805956 != 7805951) will be corrected by w(rite).
The backup GPT table is corrupt, but the primary appears OK, so that will be used.

Note: Here you should use /dev/sdd13 (user-data partition) only as other partitions may have useful data required to boot.


I am unable to see the UFS chip as "/dev/sdd. I currently am booting Debian from an SD card and do not have Debian flashed to the internal UFS chip. Do I have to have to have Linux running on the UFS to recognize it from the operating system running on the SD card? I also noticed that the Debian SD image does not have any SCSI or UFS modules compiled. Is this not a problem?
