This is short introduction of installing the Android-BSP into eMMC of the TQMa53

1. Prepare your Linux host
2. Check for nessesary tools
3. Download the BSP from TQ-Website
4. Set nessesary variables for the install script
5. Extract the BSP to your development folder
6. Configure the make file
7. Deploy the binary Android image via tftp to your TQMa53

Please check the following tools are available and install if nessesary

which dd
which sudo
which tar
which sed
which make
which bunzip2
which parted
which tar
which mkfs.vfat
which mkfs.ext4
which mkfs.ext3

Also check if a nfs server and a tftp server are installed.

The Android BSP can be downloaded in the Android downloadsection of this wiki or at the TQ-Website in the Modulsection.

1. Bla 1
2. Bla 2
   1. Bla 3
      1. Bla 4

Please define the following enviroment variables

export MY_VERSION=20130224-2
export MY_ANDROID=/my_develop/android/tqma53
export MY_DISTRIB=${MY_ANDROID}/distrib/${MY_VERSION}
export ANDROID_MK=${MY_DISTRIB}/scripts/android_binary.mk

After downloading the BSP and configuring the enviroment variables create the MY_DISTRIB folder and extract the downloaded BSP into it

mkdir -p ${MY_DISTRIB}
tar xjf android-tqma53-${MY_VERSION}.tar.bz2 -C ${MY_DISTRIB} 

Now it's time to configure the makefile.

1. set the sdcard reader (eg. /dev/sdd)
2. set IP-adresses of the host, target and gateway
3. define the tftproot folder
4. define the nfs_client_ip

The make file is accessable via $ANDORID_MK

 nano ${ANDROID_MK} 

To open the makefile

and edit the marked points

First copy images from distrib folder to the image folder

 make --makefile ${ANDROID_MK} cp_images 

Copy the image into the tftproot

  make --makefile ${ANDROID_MK} cp_image_tftpboot_01 

Start the MBa53 and go into the Barebox enviroment by pressing any key

After starting the MBa53 , type on your Linux host the following command

 make --makefile ${ANDROID_MK} cp_image_board_01 

and follow the onscreen instructions.

Example instructions

# On the barebox command line:
# Write the image to /dev/disk0
# !!!!! This will overwrite the bootloader on /dev/disk0 !!!!! 

eth0.ipaddr=172.21.16.3
eth0.netmask=255.255.0.0
eth0.serverip=172.21.10.175
eth0.gateway=172.21.2.1
tftp android-image-tqma53_01 /dev/disk0 

After copy the files via tftp in the eMMC power off the MBa53 and and set the DIP-Switches “S1”,“S2” and “S3” in order to boot from eMMC

S1-1,2 off
S2-6 on
S2-7 on, other S2-Switches off
S3-3 on
S3-5 on, other S3-Switches off

You can insert an SD-card into slot X6 on the target. It will be only used for the /mnt/sdcard partition

After about 3min the GUI of Android appears and it is ready to use
