EMMC Flash Storage
This feature is only available in WalnutPi Gen 1 images V2.5.0 and above.
The WalnutPi 2B can be configured with an EMMC flash storage version, with a default capacity of 32GB. The transfer speed is much faster than an SD card. It can be used to install the WalnutPi system or as a storage drive.
EMMC as System Boot Drive
Flash the WalnutPi OS to EMMC and boot from it. Refer to: EMMC Image Flashing Method
EMMC as a Storage Drive
When the WalnutPi 2B boots from an SD card, you can set the EMMC to be used as a storage drive, effectively giving you a 32GB hard drive.
The WalnutPi system includes a quick setup command:
sudo set-emmc to_disk
This command configures the EMMC as a disk drive. It will format the EMMC and erase all content. Please back up important files beforehand.
After running, a prompt will appear. Press "y" to continue:
A successful setup looks like the following:
You will see a ~32GB drive appear on the desktop.
Double-click to mount and use it. A prompt will ask for the password, which is the system password, i.e., pi.
EMMC Formatting
Quick format (recommended):
sudo set-emmc erase-quick
Full format (will be very slow):
sudo set-emmc erase-overwrite
