@b{Note}: This section is imcomplete, if needed please ask to the
mailing list.
In case you suspect to have RAM issues and are not even able to boot
@i{barebox}, this package offers the program @i{g45memtest}. It is a
merge of @i{at91boot} and @code{commands/memtest.c} from barebox, with
the small @i{printf} I use in other projects (e.g. @i{pptp}).
The binary is included in the package as @code{binaries/g45memtest}.
It should be loaded like @code{at91boot}: it configures the RAM and
the PLL, and then runs the test.
The source is distributed as a patch-set over @i{at91boot} (the same
version we use to boot the switch), in @code{patches/g45memtest}. To
compile, untar the source, apply the patches and compile. The
following commands are what I used to compile it (you will need to set
@code{CROSS_COMPILE} first, though).
@example
tar xzf ${WRS_DOWNLOAD_DIR}/at91bootstrap-3-3.0.tar.gz
cd at91bootstrap-3-3.0
git init
git add .
git commit -m "original code"
git am --whitespace=nowarn $WRS_BASE_DIR/../patches/g45memtest/00*
make at91sam9g45ek_defconfig
make
@end example
The output binary is the only file called ``@code{binaries/*.bin}'',
that should be renamed to @code{g45memtest}.
