SOFTWARE development:
Overview
The board comes with Linux preloaded in the NAND and DATAFLASH flash
memories. It's based on a custom-built kernel and a Debian 5.0 userland. To use it, connect a
null-modem cable to the board and to a serial port on your computer, start a terminal program
(e.g. HyperTerminal on Windows, minicom on Unix systems) and configure it to use a
115200 baud rate, 8 data bist, 1 stop bit and no parity and no flow control. Then apply power
to the board (use a 5VDC regulated power supply with at least 500mA output current) and
you should see the board start-up messages. The default root password is 'olimex'.
Restoring the default bootloader and kernel
If for some reason you need to restore the default factory configuration of the board,
the procedure is as follows:
First install the ATMEL AT91-ISP v1.12 package which comes on the disk. Reboot
the computer if needed.
Remove the NANDF_E and DF_E jumpers on the SAM9-L9260 board and power it
up. Connect an USB cable to the USB_D connector on the board and wait for the board to be
detected (the driver should already be installed by the AT91-ISP v1.12 package, so let
Windows search for it).
Close the NANDF_E and DF_E jumpers and run the
at91sam9260_demo_linux_dataflash.bat file from the sam9-l9260-samba directory. After a
while the log file will be displayed and the system should be restored to the default state.
WARNING! This procedure erases the whole NAND flash and the root filesystem will also
be destroyed and reset to its factory defaults in the process.
After a successful script execution the bootloaders and the Linux uImage will be
placed in DATAFLASH and the root filesystem will be placed in NANDFLASH. The reason
to boot from DATAFLASH is an AT91SAM9260 chip errata issue.
Alternative on-board root filesystem restore procedure
Boot-up the board with an alternate root filesystem (e.g. a USB flash drive, NFS
exported filesystem...) and use the following command (assuming that the rootjffs2.img file is
available in.)
sam9-l9260:~# flash_eraseall -j /dev/mtd1
sam9-l9260:~# nandwrite -a /dev/mtd1 /rootjffs2.img
You may get some errors about bad blocks not being erased - this is normal and is related to
the priciple of operation of NAND flashes. After the process is completed, reboot the board.
Running with another root filesystem
You may choose to use another media for the root filesystem for various reasons more capacity, faster access, etc. A complete root tree is archived in the sources/sam9-l9260rootfs.tar.bz2 file. It can be extracted to an empty ext3 partition on an USB drive or to some
NFS exported directory. Then you need to tell the kernel where to find the root - this is
accomplished by interrupting the u-boot process at the "Hit any key to stop autoboot:..."
prompt and setting the bootargs variable. For example, to boot from a USB flash drive, the
command is:
U-Boot> setenv bootargs mem=64M console=ttyS0,115200 root=/dev/sda1 rootdelay=10
and for booting from an NFS server at adress 192.168.0.75:
U-Boot> setenv bootargs mem=64M console=ttyS0,115200 root=/dev/nfs
nfsroot=192.168.0.75:nfsroot,proto=tcp ip=192.168.0.222:192.168.0.75
Toolchain
The sources for the bootloaders and the Linux kernel must be compiled under Linux
PC host. We don't intend to support Cygwin.
The projects were compiled using Codesourcery G++ lite 2009q1, freely available
from http://www.codesourcery.com. A convenience tarball is provided that contains the
Codesourcery binaries along with some useful shell scripts. This tarball must be extracted in
user's home directory. Example:
cd $HOME
tar xjf codesourcery-toolchain-2009q1-repack.tar.bz2
The latter will create a directory
$HOME/bin/codesourcery-armgcc-2009q1
Along with some shell scripts that must be sourced before compilation:
$HOME/bin/linux_cross_compile.sourceme
$HOME/bin/bootloader_cross_compile.sourceme
The latter shell scripts would add the cross compiler binaries to the PATH environment
variable and will set the ARCH and CROSS_COMPILE variables to arm and arm-nonelinux-gnueabi-/arm-none-eabi- respectively.
Building a custom kernel
The recommended build method is to use a cross-compiler. Building natively should
also work but would be very time-consuming. At the moment of this writing, the current
kernel version is 2.6.31-rc3, for which a pre-patched tarball is provided. After extracting the
sources in a temporary directory you can build the default kernel by typing
$ source $HOME/bin/linux_cross_compile.sourceme
$ make sam9_l9260_defconfig
$ make uImage
After the compilation, the kernel should be available at arch/arm/boot/uImage. If the
build process fails to detect the mkimage program then you need to get it and put it in your
PATH. The easiest way is to compile U-Boot and fetch it from the u-boot/tools subdirectory.
The new kernel can be transferred to the board by various means - e.g. use the board
restoration process and change the kernel in there, tftpboot-ing the board, etc.
Convenience GIT patches for the kernel are also provided in a separate tarball.
Building the bootstrap binary
Extract the sources from source/at91bootstrap-2.4-olimex.tar.bz2 to your working
directory and issue the following commands:
$ source $HOME/bin/bootloader_cross_compile.sourceme
$ make sam9_l9260_defconfig
If everything is correct, the resulting binary file will be located in the /binaries
directory.
Building U-Boot
Extract the sources from source/u-boot-olimex-git20090716.tar.bz2 and issue:
$ source $HOME/bin/bootloader_cross_compile.sourceme
$ make sam9l9260_config
$ make
Cross-compiling a simple "hello world" example
Extract one of the provided cross-compilers on your host system and add it to the
PATH variable. Use the cross-compiler to build the example, then transfer it to the board by
e.g. USB flash drive, http download etc.
Example commands:
----- On the host system ----$ source $HOME/bin/linux_cross_compile.sourceme
$ cat > hello.c
#include <stdio.h>
int main(void)
{
unsigned int i;
printf("\r\nProba proba ");
for (i=0; i<10; i++)
printf("\r\n%d", i);
return 0;
}
^D
$ arm-none-linux-gnueabi-gcc -o hello hello.c
$ cp hello ~/htdocs/
----- On the board ----~ # wget http://192.168.0.xx/hello
~ # chmod 777 hello
~ # ./hello
Proba proba

Using JTAG to program the board
A sample project is provided in the “TEST_BUTT” directory that demonstrates how
to write a project that runs directly on the core, without the need of an operating system. It
was developed using IAR Embedded Workbench for ARM ver. 4.42A with a Segger J-Link
JTAG adapter
Common Questions
Q: When booting from the internal NAND flash the board seems to hang at "INIT: version
2.86 booting" and/or "Activating swap...done" lines
A: When mounting the JFFS2 root filesystem, the system performs a consystency check
(similar to fsck). This almost blocks all access to the nand flash and the system appears to
hang. Please wait - on a first boot of a new filesystem this could take up to 5 minutes and is
considered normal.
Q: There are messages "Buffer I/O error on device mtdblock0, logical block 0;end_request:
I/O error, dev mtdblock0, sector 0" during boot-up. Is there a problem on the board?
A: These messages indicate incorrect OOB records in the part of the flash where the
bootloader is stored and are due to the version of SAM-BA which is used to write the various
parts of the bootloader. For all pracical reasons the above messages are harmless.
Q: The I/O operations are slow when using the on-board nand flash or USB flash drive.
A: When doing a sequential read/write (e.g. one single large file) flash memories can be fast.
When reading/writing many small files the performance will be really low.
Q: How to boot from the on board DataFlash?
A: Make sure that NANDF_E jumper is not connected and DF_E jumer is connected. If the
dataflash has been correctly programmed, the board should start up.
Q: Is the SD/MMC card supported?
A: The SD/MMC card is fully supported, including detection of card insertion/removal and
write lock
Q: What do the two LED's indicate?
A: These two leds are driven by default by the linux LED driver. The STAT LED is switched
on NAND memory access. The PWR_LED LED is blinking with a distinctive heartbeat
pattern and a frequency that depends on the system load.
Q: The system time is lost after reset, how to avoid that?
A: Unfortunately the Linux AT91SAM9 RTC driver is not yet operational. When it is
completed, you would just need a standard 3V battery at the socket at the back of the board.
Until then please set the date manually or use a network time synchronization utility as
ntpdate. Note also that AT91SAM9260 chips have a RomBOOT errata issue where
RomBOOT incorrectly resets the RTT on every system reset.
