board: asus: transformer: add ASUS Transformer T20 family support
The Asus Eee Pad Transformer family are 2-in-1 detachable/slider tablets developed by Asus that run the Android operating system. The Eee Pad Transformers feature a 10.1-inch (260 mm) display, an Nvidia Tegra 2 dual-core chip, 1 GB of RAM, and 16/32 GB of storage. Transformers board derives from Nvidia Ventana development board. This patch brings support for all 3 known T20 Transformers: - Asus Eee Pad Transformer TF101 - Asus Eee Pad Transformer TF101G - Asus Eee Pad Slider SL101 Tested-by: Robert Eckelmann <longnoserob@gmail.com> # ASUS TF101 Tested-by: Antoni Aloy Torrens <aaloytorrens@gmail.com> # ASUS TF101 Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com>

U-Boot for the ASUS Eee Pad Transformer device family
|
||||
=====================================================
|
||||
|
||||
``DISCLAMER!`` Moving your ASUS Eee Pad Transformer/Slider to use U-Boot
|
||||
assumes replacement of the vendor ASUS bootloader. Vendor Android firmwares
|
||||
will no longer be able to run on the device. This replacement IS reversible.
|
||||
|
||||
Quick Start
|
||||
-----------
|
||||
|
||||
- Build U-Boot
|
||||
- Process U-Boot
|
||||
- Flashing U-Boot into the eMMC
|
||||
- Boot
|
||||
- Self Upgrading
|
||||
|
||||
Build U-Boot
|
||||
------------
|
||||
|
||||
Device support is implemented by applying config fragment to a generic board
|
||||
defconfig. Valid fragments are ``tf101.config``, ``tf101g.config`` and
|
||||
``sl101.config``.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ export CROSS_COMPILE=arm-linux-gnueabi-
|
||||
$ make transformer_t20_defconfig tf101.config # For TF101
|
||||
$ make
|
||||
|
||||
After the build succeeds, you will obtain the final ``u-boot-dtb-tegra.bin``
|
||||
image, ready for further processing.
|
||||
|
||||
Process U-Boot
|
||||
--------------
|
||||
|
||||
``DISCLAMER!`` All questions related to the re-crypt work should be asked
|
||||
in re-crypt repo issues. NOT HERE!
|
||||
|
||||
re-crypt is a tool that processes the ``u-boot-dtb-tegra.bin`` binary into form
|
||||
usable by device. This process is required only on the first installation or
|
||||
to recover the device in case of a failed update.
|
||||
|
||||
Permanent installation can be performed either by using the nv3p protocol or by
|
||||
pre-loading just built U-Boot into RAM.
|
||||
|
||||
Processing for the NV3P protocol
|
||||
********************************
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ git clone https://gitlab.com/grate-driver/re-crypt.git
|
||||
$ cd re-crypt # place your u-boot-dtb-tegra.bin here
|
||||
$ ./re-crypt.py --dev tf101
|
||||
|
||||
The script will produce a ``repart-block.bin`` ready to flash.
|
||||
|
||||
Processing for pre-loaded U-Boot
|
||||
********************************
|
||||
|
||||
The procedure is the same, but the ``--split`` argument is used with the
|
||||
``re-crypt.py``. The script will produce ``bct.img`` and ``ebt.img`` ready
|
||||
to flash.
|
||||
|
||||
Flashing U-Boot into the eMMC
|
||||
-----------------------------
|
||||
|
||||
``DISCLAMER!`` All questions related to NvFlash should be asked in the proper
|
||||
place. NOT HERE! Flashing U-Boot will erase all eMMC, so make a backup before!
|
||||
|
||||
Permanent installation can be performed either by using the nv3p protocol or by
|
||||
pre-loading just built U-Boot into RAM.
|
||||
|
||||
Flashing with the NV3P protocol
|
||||
*******************************
|
||||
|
||||
Nv3p is a custom Nvidia protocol used to recover bricked devices. Devices can
|
||||
enter it either by using ``wheelie`` with the correct ``blob.bin`` file or by
|
||||
pre-loading vendor bootloader with the Fusée Gelée.
|
||||
|
||||
With nv3p, ``repart-block.bin`` is used. It contains BCT and a bootloader in
|
||||
encrypted state in form, which can just be written RAW at the start of eMMC.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ wheelie --blob blob.bin
|
||||
$ nvflash --resume --rawdevicewrite 0 1024 repart-block.bin
|
||||
|
||||
When flashing is done, reboot the device.
|
||||
|
||||
Flashing with a pre-loaded U-Boot
|
||||
*********************************
|
||||
|
||||
U-Boot pre-loaded into RAM acts the same as when it was booted "cold". Currently
|
||||
U-Boot supports bootmenu entry fastboot, which allows to write a processed copy
|
||||
of U-Boot permanently into eMMC.
|
||||
|
||||
While pre-loading U-Boot, hold the ``volume down`` button which will trigger
|
||||
the bootmenu. There, select ``fastboot`` using the volume and power buttons.
|
||||
After, on host PC, do:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ fastboot flash 0.1 bct.img
|
||||
$ fastboot flash 0.2 ebt.img
|
||||
$ fastboot reboot
|
||||
|
||||
Device will reboot.
|
||||
|
||||
Boot
|
||||
----
|
||||
|
||||
To boot Linux, U-Boot will look for an ``extlinux.conf`` on MicroSD and then on
|
||||
eMMC. Additionally, if the Volume Down button is pressed while booting, the
|
||||
device will enter bootmenu. Bootmenu contains entries to mount MicroSD and eMMC
|
||||
as mass storage, fastboot, reboot, reboot RCM, poweroff, enter U-Boot console
|
||||
and update bootloader (check the next chapter).
|
||||
|
||||
Flashing ``repart-block.bin`` eliminates vendor restrictions on eMMC and allows
|
||||
the user to use/partition it in any way the user desires.
|
||||
|
||||
Self Upgrading
|
||||
--------------
|
||||
|
||||
Place your ``u-boot-dtb-tegra.bin`` on the first partition of the MicroSD card
|
||||
and insert it into the tablet. Enter bootmenu, choose update the bootloader
|
||||
option with the Power button and U-Boot should update itself. Once the process
|
||||
is completed, U-Boot will ask to press any button to reboot.
