File called Start_L4T_Docs.html inside of Jetpack contains a good description of the packages that it contains. Let's call $DEVDIR the path where you installed your development directory or JetPack.
File called Start_L4T_Docs.html inside of Jetpack contains a good description of the packages that it contains. Let's call $DEVDIR the path where your L4T development directory is.


* '''For TX1'''
<pre>
<pre>
export DEVDIR=$HOME/JetPack-L4T-3.1
export DEVDIR=$HOME/JetPack-L4T-3.1/64_TX1/Linux_for_Tegra_64_tx1
 
firefox $DEVDIR/Start_L4T_Docs.html &
</pre>
</pre>


1) In order to download the source code you can run the script called source_sync.sh


* '''For TX2'''
<pre>
<pre>
cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1
export DEVDIR=$HOME/JetPack-L4T-3.1/64_TX2/Linux_for_Tegra_tx2
./source_sync.sh
</pre>
</pre>


This will download the bootloader and kernel.
Then Open the documentation:
 
2) It downloads all the kernel tree but you need to specify the tag, looking into the script it seems that the tags should be specified with k and u parameters
 
<pre>
<pre>
Use: source_sync.sh [options]
firefox $DEVDIR/../../Start_L4T_Docs.html &
Available general options are,
    -h    :    help
    -e    : exit on sync error
    -d DIR : root of source is DIR
 
By default, all sources are downloaded.
Only specified sources are downloaded, if one or more of the following options are mentioned.
 
    -k [TAG]: Download kernel source and optionally sync to TAG
    -u [TAG]: Download u-boot source and optionally sync to TAG
</pre>
</pre>


Repositories
1) In order to download the source code you can run the script called '''source_sync.sh'''


<pre>
<pre>
k:kernel:nv-tegra.nvidia.com/linux-3.10.git:
cd $DEVDIR/
u:u-boot:nv-tegra.nvidia.com/3rdparty/u-boot.git:
./source_sync.sh
</pre>
</pre>


you can see the repositories on the web looking for:
This will download the bootloader and kernel.
 
<pre>
http://nv-tegra.nvidia.com/gitweb/?o=age
 
http://nv-tegra.nvidia.com/gitweb/?p=linux-3.10.git;a=summary
http://nv-tegra.nvidia.com/gitweb/?p=3rdparty/u-boot.git;a=summary
</pre>
 
3) It will download the git repositories for kernel and uboot but you need to specify the branch or the tag
 
Branch:


<pre>
When syncing, you'll be asked for a tag, lets use '''tegra-l4t-r28.1''' for both Kernel and uboot.
cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/sources/kernel_source
git branch -a
git checkout l4t/l4t-r24.2
 
cd $DEVDIR/64_TX1/Linux_for_Tegra_64_tx1/sources/u-boot_source
git branch -a
git checkout l4t/l4t-r24.2
</pre>
 
Or if you want to download a tag then the command should look like:
 
<pre>
./source_sync.sh -k tegra-l4t-r24.2 -u tegra-l4t-r24.2
</pre>
