I'm trying to run Debian on the Android 4.4 (modded with cyanogenmod) that's installed on my nexus 10 to external sdcard. I'm reading this tutorial :


I've attached the Leef microSD microUSB Connector to the mini usb port of my nexus 10 as you can see here :

I've created two partitions on the sd card,as explained on the tutorial. The first is formatted with fat fs and the second one with ext3 file system. This is what I did when I've prepared the sd card partitions on the desktop computer :

Disk /dev/sdf: 64.0 GB, 64021856256 bytes
255 heads, 63 sectors/track, 7783 cylinders, total 125042688 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0004504c

   Device Boot      Start         End      Blocks   Id  System
/dev/sdf1            2048    32767999    16382976    b  W95 FAT32
/dev/sdf2        32768000   125042687    46137344   83  Linux

When I attach the leef connector,only the fat32 partition is recognized by android,but not the ext3. This is the mount points that I see :

To proceed with the tutorial I need to mount the second partition where should be installed the debian OS. How can I do this ? thanks.

    How have you formatted the 2nd partition? mkfs.ext3?

I've fixed the problem by myself with these commands :

mount -o rw,remount /

mount -t ext4 /dev/block/sda2 /mnt/deb

    You could try mount -t auto ... for both partitions to see if it recognizes the correct fs type.

  • mount -t auto didn't work
