Apalis iMX8 Module
==================
- SoM: https://www.toradex.com/computer-on-modules/apalis-arm-family/nxp-imx-8
- Carrier board: https://www.toradex.com/products/carrier-board/apalis-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
--------------------------------------
.. code-block:: bash
$ git clone -b imx_4.14.78_1.0.0_ga https://github.com/nxp-imx/imx-atf
$ cd imx-atf/
$ make PLAT=imx8qm bl31
Get scfw_tcm.bin and ahab-container.img
---------------------------------------
.. code-block:: bash
$ wget https://github.com/toradex/meta-fsl-bsp-release/blob/toradex-sumo-4.14.78-1.0.0_ga-bringup/imx/meta-bsp/recipes-
bsp/imx-sc-firmware/files/mx8qm-apalis-scfw-tcm.bin?raw=true
$ mv mx8qm-apalis-scfw-tcm.bin\?raw\=true mx8qm-apalis-scfw-tcm.bin
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
$ chmod +x firmware-imx-8.0.bin
$ ./firmware-imx-8.0.bin
Copy the following binaries to the U-Boot folder:
.. code-block:: bash
$ cp imx-atf/build/imx8qm/release/bl31.bin .
$ cp u-boot/u-boot.bin .
Copy the following firmware to the U-Boot folder:
.. code-block:: bash
$ cp firmware-imx-8.0/firmware/seco/ahab-container.img .
Build U-Boot
------------
.. code-block:: bash
$ make apalis-imx8_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://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fgithub.com%2FNXPmicro%2Fmfgtools%2Freleases
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
