Format the built-in eMMC storage on an Orange Pi Plus

March 7, 2016

To use the built-in 8GB of eMMC storage on the Orange Pi Plus as a writable volume in Linux, you need to delete the existing partitions (I think mine were formatted as FAT/WIN32), create a new partition, format the partition, then mount it:

  1. Delete the existing partitions:
    1. sudo fdisk /dev/mmcblk1
    2. p to list all partitions, then d and a number to delete all existing partitions, then w to write the changes.
  2. Create a new partition:
    1. sudo fdisk /dev/mmcblk1
    2. n to create a new partition, then use all the defaults, then w to write the changes.
  3. Format the partition: sudo mkfs.ext4 -L "emmc" /dev/mmcblk1p1
  4. Create a mount point: sudo mkdir /emmc
  5. Mount the disk: mount /dev/mmcblk1p1 /emmc

Hi Jeff I have an Orange Pi Pc Plus working (very nice) but I have installed on the EMMC Flash an android from youtube: https://www.youtube.com/watch?v=EZ0zLwynu4Q. The problem is I am not very good at Linux/Android and I'd like to be able to uninstall it in order tu use it for diferent proyects. I have written to the person who put it on youtube but I have not had any answer. I wonder if you would be so kind as to take a look at it and tell me how to do it - that is to uninstall it -
I thank you in advance ( even if you don't answer ) I understand that you may by a bussy person and me, an old 71 Y.O retired, trying to keep up with times hahaha.
Excuse if my English is not the best (this is not a translation) I lived in the UK for nine years ..... but too long ago. I live now in my home town Seville - Spain.
Anyway thanks again and I godbless:
Manuel Medrano.

Why?

You need to run the mount command as sudo (so sudo mount...). Also, all those other errors (File exists and command not found) are just saying that you already created the /emmc directory.
