These commands won't work:
fdisk -l #outputs nothing... su; fdisk -l #nothing.. sudo fdisk -l #sudo not found... parted -l #parted not found...
Is there any app that shows that easly?
For now I had to attach the sdcard to PC and let Linux mount it, I found the partition was
ext3 and not
ext2 that I thought! All I read says partition must be mounted to know its type. I think we must create a path and mount it with automatic detection and see mount output to know the partition type.
