A kernel +``system.dtb`` is needed to boot into the system. Both are not part of +u-boot, but are be provided through OpenEmbedded using Enclustra's meta-layer. + +Generally the bitstream files depend on the logic design, but the meta-layer +provides a demo design. Copy the ``bitstream.periph.rbf`` and +``bitstream.core.rbf`` from your design or OpenEmbedded's deploy directory. The +``fpga.its`` in board/enclustra then is used to bundle them. + + .. code-block:: bash + + $ cp <from quartus design>/bitstream.periph.rbf ./ + $ cp <from quartus design>/bitstream.core.rbf ./ + $ ./tools/mkimage -E -f ./board/enclustra/mercury_aa1/fpga.its fpga.itb + +Format the SD card, and copy the following artifacts to the mounted boot +partition, e.g. on /dev/sda. + + .. code-block:: bash + + $ mkfs.vfat -n boot /dev/sda1 + $ mount /dev/sda1 /media/boot + $ cp ./{boot.scr,u-boot.img,fpga.itb,Image,system.dtb} /media/boot/ + $ umount /dev/sda1 + +Flash the SPL directly. + + .. code-block:: bash + + $ sudo dd if=./spl/u-boot-splx4.sfp of=/dev/sda2 conv=fdatasync bs=4k status=progress + +Format and flash a rootfs from image or files to the third partition. + + .. code-block:: bash + + $ mkfs.ext4 -L rootfs /dev/sda3 + $ mount /dev/sda3 /media/rootfs + $ tar xf ./rootfs.tar -C /media/rootfs + $ umount /dev/sda3 + +Boot Media +---------- + +Alternative boot media are possible as officially documented by Enclustra. + +* Micro-SD card +* eMMC +* QSPI + +Note: eMMC and QSPI can be flashed from off the u-boot shell.

Approaches +are described consistently in the official Enclustra documentation according to +their releases mentioned as links. + +Before turning on the setup, make sure to have the correct voltage configured +at the carrier board, using the jumpers on the voltage pin header.
