Format eMMC in EXT3
I want to write in Linux Image at eMMC.
Therefore I was going to format eMMC in EXT3 form,
but the following messages were displayed and did not get along well.
Please tell me how I should format it.
root@h3ulcb:/mnt# fdisk /dev/mmcblk0 Device contains neither a valid DOS partition table, nor Sun, SGI, OSF or GPT dl Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that the previous content won't be recoverable. The number of cylinders for this disk is set to 238592. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): d No partition is defined yet!
