Getting Started#

Step 1: Connect your hardware#

Connect the DEBUG port of the AT91SAM9260 board to the first serial port of your windows machine. Install the SAM-BA application provided by Atmel. Connect the board with Windows Machine using USB Cable.

Step 2: Build the BSP#

You can build an OS image from the source code or the binary components contained in a BSP package. For instructions about building an OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual. After Building the BSP three bin files will be created in images directory.
mkflashimage script creates a combined IPL/IFS image as ipl-ifs-at91sam9260.bin
The mkflashimage script:

# script to build a binary IPL and boot image for ATMEL AT91SAM9260 Evaluation Kit board
# NOTE the image (ipl-ifs-at91sam9260.bin) must be built as binary, i.e. [virtual=armle,binary] in the buildfile 
set -v

#       Convert IPL into BINARY format
${QNX_HOST}/usr/bin/ntoarm-objcopy --input-format=elf32-littlearm --output-format=binary ../install/armle/boot/sys/ipl-at91sam9260 ipl-tmp-at91sam9260.bin

#       Pad BINARY IPL
mkrec -s4k -ffull -r ipl-tmp-at91sam9260.bin > ipl-at91sam9260.bin

#       Combine the BINARY IPL with the BINARY OS Image
cat ./ipl-at91sam9260.bin ./ifs-at91sam9260.bin > ipl-ifs-at91sam9260.bin

#       Cleaning up temporary files
rm -f *tmp*

Step 3: Download the Bootable IFS image.#

The Boot Program integrates different programs that manage download and/or upload into the different memories of the product. First, it initializes the Debug Unit serial port (DBGU) and the USB High Speed Device Port.
  • Then NAND Flash Boot program is executed. The NAND Flash Boot program searches for a valid application in the NAND Flash memory. If a valid application is found, this application is loaded into internal SRAM and executed by branching at address 0x0000_0000 after remap.
  • If no NAND Flash Boot program is found, the Data-Flash Boot program is then executed. It looks for a sequence of seven valid ARM exception vectors in a Data-Flash connected to the SPI. All these vectors must be B-branch or LDR load register instructions except for the sixth vector. This vector is used to store the size of the image to download. If a valid sequence is found, code is downloaded into the internal SRAM. This is followed by a remap and a jump to the first address of the SRAM.If no valid ARM vector sequence is found, SAM-BA Boot is then executed. It waits for transactions either on the USB device, or on the DBGU serial port.

Install and setup SAM-BA#

1. Install "AT91-ISP v1.12.exe" .

2. Intall "ActiveTcl8." i.e.TCL environment which is used by SAM-BA (any other TCL environment can also be used) .

3. Connect serial cable with windows machine, and use any serial port application such as teraterm or hyperterminal, and attach it with COM device, with baud rate set as 115200. Make sure the on-board data flash and NAND flash contain no bootable images.

4. Restart the board, hyperterminal will be showing following message .


5. Connect usb cable with windows machine, It will prompt with a new usb hardware found message, and will try to install the corresponding driver.

6. Check device has enumerated properly by looking into device manager .

7. Start SAM-BA 2.6 with \usb\ARM0 as connection.

Loading the IFS image using SAM-BA#

  • Select the Data-Flash AT45DB/DCB tab in SAM-BA Application. Execute the Enable Data-flash on CS0 script.
  • Select the ipl-ifs-at91sam9260.bin file to be sent to the target, and then press Send File. Depending on the size of your file, it will take a few seconds up to a minute.
Press the reset button, now on your terminal you will see output as follows:

You can test the OS simply by executing any shell builtin command or any command residing within the OS image (e.g. ls). 

Summary of driver commands#

The driver command lines below are specific to the Atmel AT91SAM9260 board. See the online docs for each driver for additional command-line options and other details.

Note: Some of the following drivers are commented out in the default buildfile. To use the drivers in the target hardware, you'll need to uncomment them in your buildfile, rebuild the image, and load the image into the board.

Known Issues for This BSP#

  • Network driver drops packet due to transmitter under run. A known HW limitation with the Ethernet transmitter and usage of slow SDRAM memory will cause the transmitter to generate under run and flush all packets/fragments in the transmitter queue. For more details about this problem refer to the Atmel AT91SAM9260 reference manual “EMACB Errata” for more details.
