From d23222a96caeca5f83d22ffd55e210da30eaa379 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20=C5=A0tetiar?= Date: Fri, 23 Nov 2018 10:33:24 +0100 Subject: [PATCH] imx6: Add support for Toradex Apalis family of CoMs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for the following computer on modules (CoM) from Toradex[A]: Apalis iMX6 Quad 2GB IT - i.MX 6Quad 800MHz, 2GB DDR3, 4GB eMMC -40° to +85° C Temp Apalis iMX6 Quad 1GB - i.MX 6Quad 1GHz, 1GB DDR3, 4GB eMMC 0° to +70° C Temp Apalis iMX6 Dual 1GB IT - i.MX 6Dual 800MHz, 1GB DDR3, 4GB eMMC -40° to +85° C Temp Apalis iMX6 Dual 512MB - i.MX 6Dual 1GHz, 512MB DDR3, 4GB eMMC 0° to +70° C Temp I've developed and tested it on Quad 2GB IT v1.1A and Dual 512MB v1.1A CoMs, using Ixora[B] carrier board v1.0A, but it should hopefuly work on Eval[C] board as well.

Download and compile imx_loader for OpenWrt from https://github.com/ynezz/imx_loader 2. Enter recovery mode as desribed in https://developer.toradex.com/knowledge-base/imx-recovery-mode 3. Connect board via USB to the host computer, check that it's connected by lsusb: 15a2:0054 Freescale Semiconductor, Inc. i.MX 6Dual/6Quad SystemOnChip in RecoveryMode 4. Copy following OpenWrt images to imx_loader directory: SPL u-boot.img u-boot-with-spl.imx openwrt-imx6-apalis-recovery.scr openwrt-imx6-apalis-squashfs.combined.bin 5.
