BTT devices
|
|
===========
|
|
|
|
Those devices are based on IMX's IMX287 SoC. The description regarding the
|
|
**btt** family of boards (i.e. `btt3` and `bttc`) is identical as the one for
|
|
the already supported **xea** board.
|
|
|
|
Building
|
|
--------
|
|
|
|
Make sure that `CROSS_COMPILE` is set appropriately:
|
|
|
|
.. code-block:: text
|
|
|
|
$ make imx28_btt3_defconfig
|
|
$ make -j4 u-boot.sb u-boot.img
|
|
|
|
Now you should see `u-boot.sb` and `u-boot.img` files in the build directory.
|
|
|
|
For initial bringup - one can use `uuu` utulity to boot till u-boot prompt
|
|
(USB connection with the board is required).
|
|
|
|
Flashing
|
|
--------
|
|
|
|
Via U-Boot:
|
|
|
|
.. code-block:: text
|
|
|
|
=> run update_spl
|
|
=> run update_uboot
|
