[Buildroot] [PATCH 1/1] configs/toradex_colibri_imx6_defconfig: new board

Fri Aug 25 15:56:59 UTC 2017

Add support to Colibri i.MX6 Toradex module.

Based on commit e7127d25c56b9af237366dac79e3b4a67b306fa4,
since the module works pretty much the same as Apalis iMX6.

+Toradex Colibri i.MX6 Computer on Module
+
+Intro
+=====
+
+The Colibri 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.
+
+https://www.toradex.com/computer-on-modules/colibri-arm-family/nxp-freescale-imx6
+
+It supports two carrier boards:
+
+Colibri Evaluation Board
+https://www.toradex.com/products/carrier-board/colibri-evaluation-carrier-board
+
+Iris Carrier Board
+https://www.toradex.com/products/carrier-board/iris-carrier-board
+
+Aster Carrier Board
+https://www.toradex.com/products/carrier-boards/aster-carrier-board
+
+Viola Carrier Board
+https://www.toradex.com/products/carrier-board/viola-carrier-board
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make toradex_colibri_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.
+
+http://developer.toradex.com/knowledge-base/flashing-linux-on-imx6-modules
+
+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.
