Colibri iMX8X Module
====================
- SoM: https://www.toradex.com/computer-on-modules/colibri-arm-family/nxp-imx-8x
- Carrier board: https://www.toradex.com/products/carrier-board/colibri-evaluation-board
Quick Start
-----------
- Build the ARM trusted firmware binary
- Get scfw_tcm.bin and ahab-container.img
- Build U-Boot
- Load U-Boot binary using uuu
- Flash U-Boot binary into the eMMC
- Boot
Get and Build the ARM Trusted Firmware
--------------------------------------
Download the imx-atf repository:
.. code-block:: bash
$ git clone -b lf_v2.6 https://github.com/nxp-imx/imx-atf.git
Compile it with an aarch64 toolchain:
.. code-block:: bash
$ make PLAT=imx8qx bl31 -C imx-atf
Get scfw_tcm.bin and ahab-container.img
---------------------------------------
Download imx-seco firmware and extract it:
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-seco-5.8.7.bin
$ sh imx-seco-5.8.7.bin --auto-accept
Copy the following firmware to the U-Boot folder:
.. code-block:: bash
$ wget https://github.com/toradex/i.MX-System-Controller-Firmware/raw/master/src/scfw_export_mx8qx_b0/build_mx8qx_b0/mx8qx-colibri-scfw-tcm.bin
$ cp ../imx-atf/build/imx8qx/release/bl31.bin .
$ cp ../imx-seco-5.8.7/firmware/seco/mx8qxc0-ahab-container.img mx8qx-ahab-container.img
Build U-Boot
------------
.. code-block:: bash
$ make colibri-imx8x_defconfig
$ make u-boot-dtb.imx
Load the U-Boot Binary Using UUU
--------------------------------
Get the latest version of the universal update utility (uuu) aka ``mfgtools 3.0``:
https://github.com/nxp-imx/mfgtools/releases
Put the module into USB recovery aka serial downloader mode, connect the USB
device to your host and execute ``uuu``:
.. code-block:: bash
sudo ./uuu u-boot/u-boot-dtb.imx
Flash the U-Boot Binary into the eMMC
-------------------------------------
Burn the ``u-boot-dtb.imx`` binary to the primary eMMC hardware boot area
partition and boot:
.. code-block:: bash
load mmc 1:1 $loadaddr u-boot-dtb.imx
setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
mmc dev 0 1
mmc write ${loadaddr} 0x0 ${blkcnt}
As a convenience, instead of the last three commands, one may also use the
update U-Boot wrapper:
.. code-block:: bash
> run update_uboot
