U-Boot for the NXP i.MX8QM EVK board

Quick Start
===========

- Build the ARM Trusted firmware binary
- Get scfw_tcm.bin and ahab-container.img
- Build U-Boot
- Flash the binary into the SD card
- Boot

Get and Build the ARM Trusted firmware
======================================

$ git clone https://github.com/nxp-imx/imx-atf
$ cd imx-atf/
$ git checkout origin/imx_4.14.78_1.0.0_ga -b imx_4.14.78_1.0.0_ga
$ make PLAT=imx8qm bl31

And copy the resulting bl31.bin to u-boot directory:

$ cp build/imx8qm/release/bl31.bin path/to/u-boot/

Get scfw_tcm.bin and ahab-container.img
=======================================

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.1.bin
$ chmod +x imx-sc-firmware-1.1.bin
$ ./imx-sc-firmware-1.1.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


And copy the following firmwares to U-Boot folder:

* `imx-sc-firmware-1.1/mx8qm-mek-scfw-tcm.bin`
* `firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img`

Build U-Boot
============
$ make imx8qm_mek_defconfig
$ make

Flash the binary into the SD card
=================================

Burn the flash.bin binary to SD card offset 32KB:

$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32

Boot
====
Set Boot switch SW2: 001100.
