VAR-SOM-MX6 - Ubuntu Linaro
Introduction
Variscite supports its VAR-SOM-MX6 with Linaro Ubuntu (11.10) distribution.
Your Ubuntu folder on your CD / FTP contains ready-to-run pre-built image which contain:Kernel, U-boot, and Ubuntu File system.
Variscite recommends the use of Ultra (class 10 and above) microSD for optimial performance.
Installation
Plug your SD card to your Linux machine, run dmesg and see which device is added (i.e. /dev/sdX). Copy the Ubuntu image to your SD card:
$ gunzip mx6-som-ubuntu-oneric-sd.vx.img.gz $ dd if=mx6-som-ubuntu-oneric-sd.vx.img of=/dev/sdX bs=4M
Boot
The default u-boot environment settings will load the on-som Nand flash based image.
In order to boot from SD-Card:
- use our standard nand-recovery image. Boot into it and flash Yocto by running "nand-recovery.sh" after boot.
- reboot the system (nand). Hit space bar to go into u-boot prompt.
- change the environment variables:
U-Boot > setenv bootcmd run bootcmd_mmc U-Boot > saveenv
This method will use the u-boot from nand while booting kernel and using fileystem from the sd-card.
The default username and password are:
Username : linaro
password: linaro
Build Kernel and U-Boot from Sources
Linux
Get sources:
$ mkdir ~/VAR-MX6-ub/ $ cd ~/VAR-MX6-ub/ $ git clone git://github.com/varigit/linux-2.6-imx.git $ cd linux-2.6-imx/ $ git checkout -b rel_imx_3.0.35_4.1.0-var17-release remotes/origin/rel_imx_3.0.35_4.1.0-var17-release
Comment:
get var_som_mx6_ubuntu_defconfig from the ftp site and relpace arch/arm/configs/var_som_mx6_ubuntu_defconfig with it.
get var_som_mx6_ubuntu_defconfig from the ftp site and relpace arch/arm/configs/var_som_mx6_ubuntu_defconfig with it.
Build the kernel:
$ make ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- mrproper $ make ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- var_som_mx6_ubuntu_defconfig $ make -j7 ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- uImage $ make -j7 ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- modules
Comment:
/dev/mmcblk0 is used here in all SD card commands. You need to use dmesg and change it to your device name.
/dev/mmcblk0 is used here in all SD card commands. You need to use dmesg and change it to your device name.
Flash the kernel to the sd-card and transfer the modules:
$ sudo dd if=arch/arm/boot/uImage of=/dev/mmcblk0 bs=512 seek=2048 conv=fsync;sync $ sudo make ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- modules_install INSTALL_MOD_PATH=/media/VAR_MX6_UB4.1/
u-boot
Get sources:
$ cd ~/VAR-MX6-ub/ $ git clone git://github.com/varigit/uboot-imx $ cd uboot-imx/ $ git checkout -b imx_v2009.08_3.0.35_4.1.0-var15 remotes/origin/imx_v2009.08_3.0.35_4.1.0-var15
Build u-boot:
$ make -j6 ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- mrproper $ make ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi- mx6q_var_som_config $ make -j6 ARCH=arm CROSS_COMPILE=arm-fsl-linux-gnueabi-
Flash u-boot to the sd-card:
$ sudo dd if=u-boot.bin of=/dev/mmcblk0 bs=512 seek=2 skip=2 conv=fsync; sync
Un mount the sdcard. Press eject first.
