Getting Started#

Step 1: Connect your hardware#

Step 2: Build the BSP#

mkflashimage script creates a combined IPL/IFS image as ipl-ifs-at91sam9261.bin
The mkflashimage script:

#!/bin/sh
# script to build a binary IPL and boot image for ATMEL AT91SAM9261 Evaluation Kit board.
# NOTE the image (ipl-ifs-at91sam9261.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 -R.data ../install/armle/boot/sys/ipl-at91sam9261 ipl-tmp-at91sam9261.bin

#       Pad BINARY IPL
mkrec -s16k -ffull -r ipl-tmp-at91sam9261.bin > ipl-at91sam9261.bin

#       Combine the BINARY IPL with the BINARY OS Image
cat ./ipl-at91sam9261.bin ./ifs-at91sam9261.bin > ipl-ifs-at91sam9261.bin

#       Cleaning up temporary files
rm -f *tmp*

Step 3A: Download the Bootable IFS image.#

• 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 "ActiveTcl8.5.5.0.287690-win32-ix86-threaded.exe" 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. Remove jumper J21 .

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

RomBOOT
>

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. Enable jumper J21 .

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-at91sam9261.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.

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

Step 3B: Reprogram the IPL.#

In case if Board is new or IPL gets corrupted, We can reprogram IPL using SAM-BA application.

• Select the Data-Flash AT45DB/DCB tab in SAM-BA application window, . Execute the Enable Data-flash on CS0 script.
• Select the ipl-at91sam9261.bin file to be sent to the target, and then press Send File. It will take a few seconds up to a minute.
• Snapshot is as follows:

Summary of driver commands#

The driver command lines below are specific to the Atmel AT91SAM9261 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.

About graphics#

LCD Displays#

• By default the driver sets up the Hitachi TX09D71VM1CCA TFT with the AT91SAM9261 reference board.

The LCD controller for the AT91SAM9261 expects colors to be in the format of BGR. The QNX graphics framework specify the colorformat as RGB. The graphics driver is now providing the entry points for the SW rendering to be done in the correct format.The file fbaccess.c implements the s/w rendering functions for rgb888 format.

Reserving Memory / Memory Restrictions#

• To ensure there is enough memory available for graphics, we recommend that memory be reserved at startup by using the -r option to startup.

startup-at91sam9261 -r 0x23dd0000,0x200000,1 -vvvvvvv

where 0x23dd0000 is the physical base address of memory, and 0x200000 is the size of memory reserved in bytes.

For a list of options available to the driver please see the at91sam9261.conf file.
