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。
kikuchi@develop:~/src/OB-KM$ git clone https://gitlab.com/centurysystems/XG-50/nuttx.git Cloning into 'nuttx'... remote: Enumerating objects: 5919, done. remote: Counting objects: 100% (5919/5919), done. remote: Compressing objects: 100% (2636/2636), done. remote: Total 380023 (delta 3950), reused 4234 (delta 2914) Receiving objects: 100% (380023/380023), 89.82 MiB | 2.63 MiB/s, done. Resolving deltas: 100% (296357/296357), done. Checking connectivity... done.
アプリケーション部分も clone します。

clone された結果です。

それぞれブランチを “XG-50/KYW01” に変更します。
kikuchi@develop:~/src/OB-KM$ cd nuttx/ kikuchi@develop:~/src/OB-KM/nuttx$ git checkout XG-50/KYW01 Branch XG-50/KYW01 set up to track remote branch XG-50/KYW01 from origin.

コンフィグレーションを行います。“centurysys-xg50/nsh_kyw01”
を使用します。
kikuchi@develop:~/src/OB-KM/apps$ cd ../nuttx/tools/ kikuchi@develop:~/src/OB-KM/nuttx/tools$ ./configure.sh centurysys-xg50/nsh_kyw01 Copy files Refreshing... kikuchi@develop:~/src/OB-KM/nuttx/tools$
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。
make
でバイナリをビルドします。

ファームウェアのバイナリができました。

OpenOCD
+ gdb
を使用してファームウェアを書き込みます。
gdb
から “c”
(continue) で実行します。
�ABCDF NuttShell (NSH) nsh>
APN などを設定します。cu
コマンドを利用します。
nsh> cu -r AT OK AT+CGDCONT=1,"IP","kddiint.lpwa.kddi.com" <--- PDPコンテキスト設定 OK AT+CGAUTH=1,1,"hogehoge","fugafuga" <--- PDPコンテキストの認証パラメータ設定 OK AT+KCOMSET=1 <--- データ通信方式設定 (PPP) OK AT+CFUN=6 <--- モジュールリセット OK
認証パラメータは、SIM により認証される回線なので使用されないため任意です。
“~” のあと “.” を入力することで cu
コマンドを終了します。
pppd
コマンドにより接続を行います。“&”
をつけてバックグラウンドで起動1)します。
nsh> pppd & pppd [11:100] nsh>
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。
