FlashPreBuildDemo

Prepare Environment

Before flashing the demo, make sure that you have installed the SAM-BA tool on your host computer.

Download Pre-built Demo Packages

Demo based on Android-2.3.5_r1	SAM9M10 MCU	SAM9G45 MCU	SAM9X5 MCU
Nand Boot	9M10/Nand (~ 46 MB, md5)	9G45/Nand (~ 45 MB, md5)	9X5/Nand (~ 45 MB, md5)
SD Boot	9M10/SD (~ 54 MB, md5)	9G45/SD (~ 53 MB, md5)	9X5/SD (~ 77 MB, md5)

These demo packages can be programmed to corresponding EK boards by using SAM-BA Tool.

Flash Pre-built Demo

There are two types of demo packages:

• NAND flash based: Android system works on NAND flash
• SD card based: Android system works on SD card

Nand Flash Based

Connect Device in SamBA Mode To PC

• Connect a USB cable between the board and PC
• Connect a serial link between DBGU connector and PC, then open a terminal emulator program on PC
• Choose the proper procedure depending on your chip
  • Power down the board
  • Check and conform to the Default Jumpers Settings
    • For other boards, please refer to the schematics respectively
  • BMS shall be configured to boot from the on-chip Boot ROM
  • Disable NAND Flash chip select
  • Power up the board
  • Verify that the USB connection is established
  • Enable NAND Flash chip select

Flash into Nandflash

After the target is connected to the PC successfully, we can run the batch file (.bat) in the pre-built package to flash the Android demo into Nandflash.

Before doing this we need to enable Nandflash chip select.

1. Unzip above Nandflash based demo package file
2. Run the batch file from the unzip folder (*.bat)
3. Wait for the log file: logfile.log (Opened by notepad.exe). This will take a few minutes. Debug messages can be observed from the DBGU port.
4. Close the logfile.log (by close the Notepad)

NOTE: If anything goes wrong, the logfile.log and the output of DBGU are helpful for you to find what the problems are.

Bootup from Nandflash

After nand flash base demo package has been flashed into your EK board:

1. Reset target EK board
2. Wait about 1 minute for android booting up

NOTE: If anything goes wrong, the output of DBGU is helpful for you to find where the problems are.

SD Card Based

Generate SD card

We need to use Linux host PC with SD card device to program SD Card based demo.

1. Unzip the SD Based Demo package.
2. Copy the demo image file (*.img, for example: Android-2.3.5_r1-sam9m10-sdboot.img) to Linux host
3. Write image file to SD Card
   
   For Linux platform you can

   $ dd if=Android-2.3.5_r1-sam9m10-sdboot.img of=/dev/sdb

   Here, we assume the demo image file is in current directory, and /dev/sdb for SD card device node as an example
   You need to specify the correct device name, or you may come across the data loss.
   
   For Windows platform, you can use the tool from https://launchpad.net/win32-image-writer/+download to write the image file to SD Card.

To find out the device node of the SD Card you are using, you could use:

$ mount

before and after you insert your SD card. The newly added device after you insert your SD Card is the device node of your SD Card.

We assume SD Card size is larger than 2GB.

Boot from SD Card

As the SD Card is chosen as the boot device, you need to disable all external booting memory

• Dataflash boot
• NOR flash boot
• NAND flash boot

Please refer to schematics for chip select configuration

1. After the SD Card has been flashed successfully, insert SD card on EK board and power on the system.
2. Wait about 1 minute for android booting

NOTE: If anything goes wrong, the output of DBGU is helpful for you to find what the problems are.

Android Booting

Following pictures show the different stage of Android booting process, this will take a few minutes:

TIPS: If the start screen is the lock screen, you can drag the lock icon to the top to unlock the screen.

Here is an example of boot log which can be received from DBGU:
