| 8 | # This script allows to deploy HelenOS conveniently to the HiKey 960 board
|
|---|
| 9 | # using the fastboot protocol. The fastboot mechanism is provided as a part
|
|---|
| 10 | # of the default UEFI firmware on HiKey 960.
|
|---|
| 11 | #
|
|---|
| 12 | # The implementation of the fastboot mechanism on HiKey 960 has several
|
|---|
| 13 | # quirks and this script tries to accommodate for them:
|
|---|
| 14 | #
|
|---|
| 15 | # * The boot image must be compressed by GZip. Uncompressed boot images are
|
|---|
| 16 | # rejected.
|
|---|
| 17 | #
|
|---|
| 18 | # * The compressed boot image must end with a device tree blob (even if
|
|---|
| 19 | # the device tree is not actually processed). A missing device tree blob
|
|---|
| 20 | # crashes the fastboot mechanism.
|
|---|
| 21 | #
|
|---|
| 22 | # * A RAM disk must be included in the final fastboot image. A missing RAM
|
|---|
| 23 | # disk crashes the fastboot mechanism. We use a fake blob for that purpose.
