====== LTE Cat.1 拡張ボード(OB-L1)の利用 ======

XG-50 に、NTT docomo LTE Cat.1 回線用オプションボード [[https://www.centurysys.co.jp/products/industrial/xgb50.html|FutureNet OB-L1]] を搭載し、
LTE Cat.1 回線を利用してみます。

===== ファームウェアのビルド =====

==== ソースコードの準備 ====

=== リポジトリから clone ===

[[https://gitlab.com/centurysystems/XG-50|GitLab]] のリポジトリを clone します。

まずは、NuttX 本体部分を clone します。

<code>
kikuchi@develop:~/src/OB-L1$ git clone https://gitlab.com/centurysystems/XG-50/nuttx.git
Cloning into 'nuttx'...
remote: Enumerating objects: 9256, done.
remote: Counting objects: 100% (9256/9256), done.
remote: Compressing objects: 100% (3942/3942), done.

Resolving deltas: 100% (296680/296680), done.
Checking connectivity... done.
kikuchi@develop:~/src/OB-L1$
</code>

アプリケーション部分も clone します。

<code>
kikuchi@develop:~/src/OB-L1$ git clone https://gitlab.com/centurysystems/XG-50/apps.git
Cloning into 'apps'...
remote: Enumerating objects: 992, done.
remote: Counting objects: 100% (992/992), done.
remote: Compressing objects: 100% (734/734), done.

Receiving objects: 100% (36554/36554), 9.03 MiB | 1.95 MiB/s, done.
Resolving deltas: 100% (29223/29223), done.
Checking connectivity... done.
kikuchi@develop:~/src/OB-L1$ 
</code>

clone された結果です。

<code>
kikuchi@develop:~/src/OB-L1$ ls -l
total 8
drwxrwxr-x 21 kikuchi kikuchi 4096  8月 17 15:56 apps
drwxrwxr-x 21 kikuchi kikuchi 4096  8月 17 15:55 nuttx
kikuchi@develop:~/src/OB-L1$ 
</code>

\\

=== ブランチの確認 ===

それぞれブランチはデフォルト(XG-50/master) のままで OK です。

<code>
kikuchi@develop:~/src/OB-L1$ cd nuttx/
kikuchi@develop:~/src/OB-L1/nuttx$ git branch 
* XG-50/master
kikuchi@develop:~/src/OB-L1/nuttx$ cd ../apps/
kikuchi@develop:~/src/OB-L1/apps$ git branch 
* XG-50/master
kikuchi@develop:~/src/OB-L1/apps$ 
</code>

\\

==== コンフィグレーション ====

コンフィグレーションを行います。''"centurysys-xg50/nsh_tickless"'' を使用します。

<code>
kikuchi@develop:~/src/OB-L1/apps$ cd ../nuttx/
kikuchi@develop:~/src/OB-L1/nuttx$ cd tools/
kikuchi@develop:~/src/OB-L1/nuttx/tools$ ./configure.sh centurysys-xg50/nsh_tickless
  Copy files
  Refreshing...
kikuchi@develop:~/src/OB-L1/nuttx/tools$ 
</code>

\\

追加のアプリケーションなどを使う場合は、''make menuconfig'' でコンフィグレーションを変更して追加することもできます。

{{:xg_series_devel:ublox_lara:make_menuconfig.png?600|make menuconfig}}

\\

==== ビルド ====

''make'' でバイナリをビルドします。

<code>
kikuchi@develop:~/src/OB-L1/nuttx/tools$ cd ..
kikuchi@develop:~/src/OB-L1/nuttx$ make

kikuchi@develop:~/src/OB-L1/nuttx$ 
</code>

\\

ファームウェアのバイナリができました。

<code>
kikuchi@develop:~/src/OB-L1/nuttx$ ls -l nuttx*
-rwxrwxr-x 1 kikuchi kikuchi 2866548  8月 17 16:00 nuttx
-rwxrwxr-x 1 kikuchi kikuchi  172432  8月 17 16:00 nuttx.bin
-rw-rw-r-- 1 kikuchi kikuchi  485063  8月 17 16:00 nuttx.hex
kikuchi@develop:~/src/OB-L1/nuttx$ 
</code>

\\

===== XG-50 への書き込み =====

''OpenOCD'' + ''gdb'' を使用してファームウェアを書き込みます。

\\

===== 動作確認 =====

''gdb'' から ''"c"''(continue) で実行します。

<code>
��ABCDFboot

NuttShell (NSH)
nsh> 
</code>

\\

==== PPP 接続 ====

''pppd'' コマンドにより接続を行います。APN / user / password はコマンドラインから指定します。\\
実際に接続する際には ''"&"'' をつけてバックグラウンドで起動((フォアグラウンドで起動すると何もできなくなります。))します。

<code>
nsh> pppd
Usage: pppd -a APN -u UserName -p Password
nsh> pppd -a dream.jp -u user@dream.jp -p dti &
pppd [4:100]
nsh> 
</code>

\\

しばらくすると接続が完了します。dmesg でログを確認することができます。
