# Simple script to create a disk image which boots to U-Boot on Pine64.
|
|
#
|
|
# This script uses boot0 binary blob (as extracted from the Pine64 Android
|
|
# image) together with a correctly prefixed U-Boot and A DOS partition table
|
|
# to create a bootable SDcard image for the Pine64. If a Kernel and DTB is
|
|
# found in ../kernel, it is added as well.
|
|
#
|
|
# U-Boot tree:
|
|
# - https://github.com/longsleep/u-boot-pine64/tree/pine64-hacks
|
|
#
|
|
# Build the U-Boot tree and assemble it with ATF, SCP and FEX and put the
|
|
# resulting u-boot-with-dtb.bin file into the ../build directory. The
|
|
# u-boot-postprocess script provides an easy way to do all that.
