Download Source code and cross compiler tool from Avalue git server

git clone giter@aes.avalue.com.tw:imx51.git

Compile U-Boot & Kernel Source code

After you download source code from Avalue GIT server, you will find a folder named “core”. Here is description for each folder & files inside.

Item Description
fsl folder with cross compile tools inside
kernel folder with kernel source code inside
Makefile Makefile for compile u-boot & kernel image
u-boot folder with u-boot souce code inside

Use command below to compile u-boot & kernel

#make rev-sa01 -j4

Use command below to compile u-boot only

#make rev-sa01-uboot -j4

Use command below to compile kernel only

#make rev-sa01-kernel -j4

Use command below to clean all the binary files in source code

#make clean

After you finish to compile source code, you will find files below. Here are description for each files

Item Description
u-boot-quad-2g.bin u-boot for SMA-IMX6QI with 2GB DDR3L memory

u-boot-solo.bin u-boot for SMA-IMX6SI with 1GB DDR3L memory
uImage-p kenrnel image file for SMA-IMX6 with PF0100 PMIC
uImage kernel image file for SMA-IMX6 with WM8326 PMIC

You will have to copy image files to path MFG-REV-SA01\Image\smarc\ of your MfgTool folder.

Bootloader : U-Boot

To modify default setting for u-boot command, you can modify following files in path core/u-boot/include/configs/

Item Description
mx6_smarc.h Default settings for SMA-IMX6 SMARC module
mx6q_rev_sa01.h Default settings for SMA-IMX6QI + REV-SA01
mx6solo_rev_sa01.h Default settings for SMA-IMX6SI + REV-SA01

Linux Kernel

Please get into folder core/kernel and use command below to load default configuration of kernel and config it

Command Description
#./run.sh rev-sa01 -j4 Command to build kernel for SMA-IMX6(WM8326PMIC) + REV-SA01
#./run.sh rev-sa01-p -j4 Command to build kernel for SMA-IMX6(PF0100) + REV-SA01
#./run.sh menuconfig Command to setup kernel configuration
#./run.sh modules Command to build kernel modules
#./run.sh clean Command to clean binary files in kernel source code

You can find update uImage in path core/kernel/arch/arm/boot

Ubuntu Root File System

Please kindly download mfgtool from hyperlink below.
MfgTool for Ubuntu

Please download and decompress it. You can find ubuntu.tar.bz2 in path MFG-REV-SA01\Image\smarc

The Ubuntu file system we provided in mfgtool is Ubuntu 12.04. Here is user name & password information.

Install System into SD Card

Please insert a SD card in the card reader on your Ubuntu development system.

1. Check device node of the SD card by command below

#cat /proc/partitions

For example, mine is /dev/sdd as below

2. Create partition for SD card

#sudo fdisk /dev/sdd
Type the following parameters (each followed by <ENTER>):
d         [delete the previous partition]
n         [create a new partition]
p         [create a primary partition]
1         [the first partition]
20480     [20480x512bytes=10MB, which leaves enough space for the kernel, the boot loader and its configuration data]
<enter>    [using the default value will create a partition that spans to the last sector of the medium]
w        [ this writes the partition table to the medium and fdisk exits]

3. Format new partition in EXT3 format

#sudo umount /dev/sdd1
#sudo mkfs.ext3 /dev/sdd1

4. install u-boot on SD card by command below

//This is command to install u-boot for SMA-IMX6SI on SD card
#sudo dd if=u-boot-solo.bin of=/dev/sdd  bs=1k seek=1 skip=1 conv=fsync
//This is command to install u-boot for SMA-IMX6QI on SD card
#sudo dd if=u-boot-quad.bin of=/dev/sdd  bs=1k seek=1 skip=1 conv=fsync
//This is command to install u-boot for SMA-IMX6QI with 2GB DDR3L on SD card
#sudo dd if=u-boot-quad-2g.bin of=/dev/sdd  bs=1k seek=1 skip=1 conv=fsync

5. Install kernel image file on SD card by command below

//This is command to install kernel for SMA-IMX6 with PMIC WM8326 on SD card
#sudo dd if=uImage of=/dev/sdd  bs=1M seek=1 conv=fsync
//This is command to install kernel for SMA-IMX6 with PMIC PF0100 on SD card
#sudo dd if=uImage-p of=/dev/sdd  bs=1M seek=1 conv=fsync

6. Get ubuntu.tar.bz2 from mfgtool and use command below to copy it on SD card

#sudo umount /dev/sdd1
#sudo mount /dev/sdd1 /mnt
#cd /mnt
#sudo tar jxpf ~/ubuntu.tar.bz2
#cd ..
#cd umount /dev/sdd1

With these steps, you had successfully install Ubuntu on SD card. Now you can insert it on SD socket on REV-SA01 and set SW1 as below before you power it on.

Modify u-boot setting to load kernel image & Ubuntu file system from SD card

1. Connect a cross-over RS232 cable between COM1 of REV-SA01 and Windows 7 system. 2. If you do not have RS232 cross over cable, please make one by yourself as below.
3. Use hyper terminal program, like PUTTY to link with i.MX6 system.
4. Power on REV-SA01 and press SPACE on keyboard to get into -boot menu.

5. Set boot device as command below in u-boot menu

SMARC U-Boot >setenv linux_cmd  ‘setenv bootargs ${linux_bootargs};mmc dev 1;mmc read ${loadaddr} 0x800 0x3000;bootm’
SMARC U-Boot > setenv linux_bootargs 'console=tty0 console=ttymxc0,115200 root=/dev/mmcblk1p1 rootwait rw'
SMARC U-Boot> saveenv
SMARC U-Boot> boot

Now you can boot from SD card w/o problem.

Install System into eMMC

1. Set SW1 on REV-SA01 as below to serial download mode

2. Use mini-USB cable to connect MINIUSB1 on REV-SA01 to Windows 7 system.

3. Run MfgTool2.exe in path MFG-REV-SA01\MFG-Tools\ and click start to flash image file.

4. It will show “Done” after flashing is finish, then click “Stop” and “Exit” to close the screen.

5. Set SW1 as below to boot from eMMC

6. Restart the system then boot in Ubuntu
