U-Boot for the Toradex Verdin iMX8M Mini Module
Quick Start
===========
- Build the ARM trusted firmware binary
- Get the DDR firmware
- Build U-Boot
- Flash to eMMC
- Boot
Get and Build the ARM Trusted Firmware (Trusted Firmware A)
===========================================================
$ echo "Downloading and building TF-A..."
$ git clone -b imx_4.14.98_2.3.0 https://source.codeaurora.org/external/imx/imx-atf
$ cd imx-atf
Please edit `plat/imx/imx8mm/include/platform_def.h` so it contains proper
values for UART configuration and BL31 base address (correct values listed
below):
#define BL31_BASE 0x910000
#define IMX_BOOT_UART_BASE 0x30860000
#define DEBUG_CONSOLE 1
Then build ATF (TF-A):
$ make PLAT=imx8mm bl31
Get the DDR Firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.4.1.bin
$ chmod +x firmware-imx-8.4.1.bin
$ ./firmware-imx-8.4.1.bin
$ cp firmware-imx-8.4.1/firmware/ddr/synopsys/lpddr4*.bin ./
Build U-Boot
============
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make verdin-imx8mm_defconfig
$ make flash.bin
Flash to eMMC
=============
> tftpboot ${loadaddr} flash.bin
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
> mmc dev 0 1 && mmc write ${loadaddr} 0x2 ${blkcnt}
As a convenience, instead of the last two commands one may also use the update
U-Boot wrapper:
> run update_uboot
Boot
====
ATF, U-boot proper and u-boot.dtb images are packed into FIT image,
which is loaded and parsed by SPL.
Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

Colibri iMX7
============
Quick Start
-----------
- Build U-Boot
- NAND IMX image adjustments before flashing
- Flashing manually U-Boot to eMMC
- Flashing manually U-Boot to NAND
- Using ``update_uboot`` script
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=arm-linux-gnueabi-
$ export ARCH=arm
$ make colibri_imx7_emmc_defconfig # For NAND: colibri_imx7_defconfig
$ make
After build succeeds, you will obtain final ``u-boot-dtb.imx`` IMX specific
image, ready for flashing (but check next section for additional
adjustments).
Final IMX program image includes (section ``6.6.7`` from `IMX7DRM
<https://www.nxp.com/webapp/Download?colCode=IMX7DRM>`_):
* **Image vector table** (IVT) for BootROM
* **Boot data** -indicates the program image location, program image size
in bytes, and the plugin flag.
* **Device configuration data**
* **User image**: U-Boot image (``u-boot-dtb.bin``)
IMX image adjustments prior to flashing
---------------------------------------
1. U-Boot for both Colibri iMX7 NAND and eMMC versions
is built with HABv4 support (`AN4581.pdf
<https://www.nxp.com/docs/en/application-note/AN4581.pdf>`_)
enabled by default, which requires to generate a proper
Command Sequence File (CSF) by srktool from NXP (not included in the
U-Boot tree, check additional details in introduction_habv4.txt)
and concatenate it to the final ``u-boot-dtb.imx``.
2. In case if you don't want to generate a proper ``CSF`` (for any reason),
you still need to pad the IMX image so i has the same size as specified in
in **Boot Data** section of IMX image.
To obtain this value, run:
.. code-block:: bash
$ od -X -N 0x30 u-boot-dtb.imx
0000000 402000d1 87800000 00000000 877ff42c
0000020 877ff420 877ff400 878a5000 00000000
^^^^^^^^
0000040 877ff000 000a8060 00000000 40b401d2
^^^^^^^^ ^^^^^^^^
Where:
* ``877ff400`` - IVT self address
* ``877ff000`` - Program image address
* ``000a8060`` - Program image size
To calculate the padding:
* IVT offset = ``0x877ff400`` - ``0x877ff000`` = ``0x400``
* Program image size = ``0xa8060`` - ``0x400`` = ``0xa7c60``
and then pad the image:
.. code-block:: bash
$ objcopy -I binary -O binary --pad-to 0xa7c60 --gap-fill=0x00 \
u-boot-dtb.imx u-boot-dtb.imx.zero-padded
3. Also, according to requirement from ``6.6.7.1``, the final image
should have ``0x400`` offset for initial IVT table.
For eMMC setup we handle this by flashing it to ``0x400``, howewer
for NAND setup we adjust the image prior to flashing, adding padding in the
beginning of the image.
.. code-block:: bash
$ dd if=u-boot-dtb.imx.zero-padded of=u-boot-dtb.imx.ready bs=1024 seek=1
Flash U-Boot IMX image to eMMC
------------------------------
Flash the ``u-boot-dtb.imx.zero-padded`` binary to the primary eMMC hardware
boot area partition:
.. code-block:: bash
=> load mmc 1:1 $loadaddr u-boot-dtb.imx.zero-padded
=> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
=> mmc dev 0 1
=> mmc write ${loadaddr} 0x2 ${blkcnt}
Flash U-Boot IMX image to NAND
------------------------------
.. code-block:: bash
=> load mmc 1:1 $loadaddr u-boot-dtb.imx.ready
=> nand erase.part u-boot1
=> nand write ${loadaddr} u-boot1 ${filesize}
=> nand erase.part u-boot2
=> nand write ${loadaddr} u-boot2 ${filesize}
Using update_uboot script
-------------------------
You can also usb U-Boot env update_uboot script,
which wraps all eMMC/NAND specific command invocation:
.. code-block:: bash
=> load mmc 1:1 $loadaddr u-boot-dtb.imx.ready
=> run update_uboot

Verdin iMX8M Mini Module
========================
Quick Start
-----------
- Build the ARM trusted firmware binary
- Get the DDR firmware
- Build U-Boot
- Flash to eMMC
- Boot
Get and Build the ARM Trusted Firmware (Trusted Firmware A)
-----------------------------------------------------------
.. code-block:: bash
$ echo "Downloading and building TF-A..."
$ git clone -b imx_4.14.98_2.3.0 \
https://source.codeaurora.org/external/imx/imx-atf
$ cd imx-atf
Please edit ``plat/imx/imx8mm/include/platform_def.h`` so it contains proper
values for UART configuration and BL31 base address (correct values listed
below):
.. code-block:: bash
#define BL31_BASE 0x910000
#define IMX_BOOT_UART_BASE 0x30860000
#define DEBUG_CONSOLE 1
Then build ATF (TF-A):
.. code-block:: bash
$ make PLAT=imx8mm bl31
Get the DDR Firmware
--------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.4.1.bin
$ chmod +x firmware-imx-8.4.1.bin
$ ./firmware-imx-8.4.1.bin
$ cp firmware-imx-8.4.1/firmware/ddr/synopsys/lpddr4*.bin ./
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make verdin-imx8mm_defconfig
$ make flash.bin
Flash to eMMC
-------------
.. code-block:: bash
> tftpboot ${loadaddr} flash.bin
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
> mmc dev 0 1 && mmc write ${loadaddr} 0x2 ${blkcnt}
As a convenience, instead of the last two commands one may also use the update
U-Boot wrapper:
.. code-block:: bash
> run update_uboot
Boot
----
ATF, U-Boot proper and u-boot.dtb images are packed into FIT image,
which is loaded and parsed by SPL.
Boot sequence is:
* SPL ---> ATF (TF-A) ---> U-Boot proper
Output:
.. code-block:: bash
