Booting

Example SD rootfs boot, prepare your SD card by partitioning it with a small (64 MB+) FAT partition and a larger ext4 partition.

Place the following files in the first partition. These files are found under the deploy/images/parallella/ directory. Additionally select the correct bitstream for your board (from deploy/images/parallella/bistreams).

  • uImage
  • parallella-mmc-boot.dtb (rename it as 'devicetree.dtb')
  • e.g. parallella_e16_headless_gpiose_7010.bit.bin (rename it as 'parallella.bit.bin')

Extract the rootfs image into the second ext4 partition. Assuming the rootfs image built is named 'core-image-epiphany', extract the tar.gz from deploy/images/core-image-epiphany-parallella.tar.gz into the root of the partition (run the tar command as root/with sudo in order ot preserve file system perms/options).

Power Parallella board up with the SD card. The system will boot up and load the kernel, and then mount the rootfs from the second partition of the SD card.
