Click to download the latest 2GB SLC eMMC image. |
| WARNING: | Make sure the SD and eMMC filesystems are mounted read only while writing any images. If dd is used to read or write a disk while a filesystem on it is mounted read/write this will result in a corrupt image. |
First boot to the initramfs. These steps should not be run from the full Debian environment, so to get back to the initramfs, first run:
tshwctl --removejp 1 && reboot
First, boot to the SD card. Once you are in the initramfs, mount a network share or usb drive containing the emmc image.
Write an Image to eMMC
# Check /mnt/root. If it shows a file "root.version", you can proceed.
# If it shows nothing, you need to wait for the Debian filesystem
until [ -e /mnt/root/root.version ]; do sleep .1; done
# Plug in a thumbdrive formatted with ext2/3/4 or fat32
mkdir /mnt/usbdev
mount -o ro /dev/sda1 /mnt/usbdev
umount -l /mnt/root/
dd if=/mnt/usbdev/emmcimage.dd bs=4M of=/dev/nbd1
sync
reboot
Save an image from eMMC
# Check /mnt/root. If it shows a file "root.version", you can proceed.
# If it shows nothing, you need to wait for the Debian filesystem
until [ -e /mnt/root/root.version ]; do sleep .1; done
# Plug in a thumbdrive formatted with ext2/3/4 or fat32
mkdir /mnt/usbdev
mount /dev/sda1 /mnt/usbdev
umount -l /mnt/root/
dd if=/dev/nbd1 bs=4M of=/mnt/usbdev/emmcimage.dd
umount /mnt/usbdev
sync
