Toradex Apalis i.MX6 Computer on Module
|
|
|
|
Intro
|
|
=====
|
|
|
|
The Apalis iMX6 is a small form-factor Computer on Module that comes
|
|
in both quad core and dual core versions based on Freescale i.MX6Q and
|
|
Freescale i.MX6D SoCs respectively. The Cortex A9 quad core and dual
|
|
core CPU peaks at 1 GHz for commercial temperature variant, while the
|
|
industrial temperature variant has a peak frequency of 800 MHz.

How to build it
|
|
===============
|
|
|
|
Configure Buildroot:
|
|
|
|
$ make toradex_apalis_imx6_defconfig
|
|
|
|
Compile everything and build the rootfs image:
|
|
|
|
$ make
|
|
|
|
How to boot the image
|
|
=====================
|
|
|
|
The board only boots from its internal flash memory eMMC, so the
|
|
bootloader image should be copied to it, following the procedures
|
|
described in Toradex website.
|
|

|
|
|
|
Buildroot prepares a "sdcard.img" in output/images/ with the kernel
|
|
image, device tree and a root filesystem, ready to be dumped on an SD
|
|
card.
|
|
|
|
$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
|
|
|
|
To boot from the SD card, you should change the U-Boot
|
|
environment. Since U-Boot is running from internal eMMC, you will need
|
|
to access its command line prompt and manually set the necessary
|
|
variables to boot from the external SD card. For convenience, you can
|
|
use uEnv.txt provided in output/images/ as a reference to create the
|
|
necessary U-Boot variables to boot from the SD card.
