Micro SD Card Creation
Replace sdX in the following instructions with the device name for the SD card as it appears on your computer.
- Zero the beginning of the SD card:
dd if=/dev/zero of=/dev/sdX bs=1M count=8
- Start fdisk to partition the SD card:
- At the fdisk prompt, create the new partitions:
- Type o. This will clear out any partitions on the drive.
- Type p to list partitions. There should be no partitions left.
- Type n, then p for primary, 1 for the first partition on the drive, and enter twice to accept the default starting and ending sectors.
- Write the partition table and exit by typing w.
- Create the ext4 filesystem:
- For e2fsprogs < 1.43:
- For e2fsprogs >= 1.43:
mkfs.ext4 -O ^metadata_csum,^64bit /dev/sdX1
- Mount the filesystem:
mount /dev/sdX1 root
- Download and extract the root filesystem (as root, not via sudo):
bsdtar -xpf ArchLinuxARM-clearfog-latest.tar.gz -C root
- Flash the bootloader files:
sh sd_fusing.sh /dev/sdX
- Unmount the partition:
- Insert the micro SD card into the ClearFog, connect ethernet, and apply power.
- Use the serial console (micro usb port on the board, if needed) or SSH to the IP address given to the board by your router.
- Login as the default user alarm with the password alarm.
- The default root password is root.
