Build U-Boot
|
||||
------------
|
||||
|
||||
Device support is implemented by applying config fragment to a generic board
|
||||
defconfig. Valid fragments are ``tilapia.config``, ``grouper_E1565.config``
|
||||
and ``grouper_PM269.config``.
|
||||
U-Boot features ability to detect grouper board revision on which it is
|
||||
loaded. Currently are supported both TI and MAXIM based WiFi-only models
|
||||
along with cellular one.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ export CROSS_COMPILE=arm-linux-gnueabi-
|
||||
$ make grouper_common_defconfig grouper_E1565.config # For maxim based grouper
|
||||
$ make grouper_defconfig # For all grouper versions and tilapia
|
||||
$ make
|
||||
|
||||
After the build succeeds, you will obtain the final ``u-boot-dtb-tegra.bin``
