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://source.codeaurora.org/external/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

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

Copy the following binaries to U-Boot folder:

$ cp imx-atf/build/imx8qm/release/bl31.bin .
$ cp u-boot/u-boot.bin .

Copy the following firmwares U-Boot folder :

$ cp firmware-imx-7.6/firmware/seco/ahab-container.img .
$ cp imx-sc-firmware-0.7/mx8qm-mek-scfw-tcm.bin	.

Build U-Boot
============
$ export ATF_LOAD_ADDR=0x80000000
$ export BL33_LOAD_ADDR=0x80020000
$ make imx8qm_mek_defconfig
$ make flash.bin
$ dd if=u-boot.itb of=flash.bin bs=512 seek=1984

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: 1100.
