166 When you install and configure the Eclipse Yocto Project

169 Installing and configuring the Plug-in results in an
170 environment that has extensions specifically designed to let
171 you more easily develop software.
172 These extensions allow for cross-compilation, deployment, and
173 execution of your output into a QEMU emulation session as well
174 as actual target hardware.
175 You can also perform cross-debugging and profiling.
176 The environment also supports performance enhancing
177 <ulink url='http://www.eclipse.org/linuxtools/'>tools</ulink>
178 that allow you to perform remote profiling, tracing,
179 collection of power data, collection of latency data, and
180 collection of performance data.

1039 Once the QEMU emulator is running the image, you can deploy
1040 your application using the Eclipse IDE and then use
1041 the emulator to perform debugging.
1042 Follow these steps to deploy the application.
1043 <note>
1044 Currently, Eclipse does not support SSH port
1045 forwarding.
1046 Consequently, if you need to run or debug a remote
1047 application using the host display, you must create a
1048 tunneling connection from outside Eclipse and keep
1049 that connection alive during your work.
1050 For example, in a new terminal, run the following:
1051 <literallayout class='monospaced'>
1052 $ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable>
1053 </literallayout>
1054 Using the above form, here is an example:
1055 <literallayout class='monospaced'>
1056 $ ssh -XY root@192.168.7.2
1057 </literallayout>
1058 After running the command, add the command to be
1059 executed in Eclipse's run configuration before the
1060 application as follows:
1061 <literallayout class='monospaced'>
1062 export DISPLAY=:10.0
1063 </literallayout>
1064 Be sure to not destroy the connection during your QEMU

709 This creates a local tag named

711 based on the branch

713 You are put into a detached HEAD state,

1254 Click "Run" to launch QEMU.
1255 <note>
1256 The host on which you are running QEMU must
1257 have the <filename>rpcbind</filename> utility
1258 running to be able to make RPC calls on a
1259 server on that machine.
1260 If QEMU does not invoke and you receive error
1261 messages involving
1262 <filename>rpcbind</filename>, follow the
1263 suggestions to get the service running.
1264 As an example, on a new Ubuntu 16.04 LTS
1265 installation, you must do the following in
1266 order to get QEMU to launch:
1267 <literallayout class='monospaced'>
1268 $ sudo apt-get install rpcbind
1269 </literallayout>
1270 After installing <filename>rpcbind</filename>,
1271 you need to edit the
1272 <filename>/etc/init.d/rpcbind</filename> file
1273 to include the following line:
1274 <literallayout class='monospaced'>
1275 OPTIONS="-i -w"
1276 </literallayout>
1277 After modifying the file, you need to start the
1278 service:
1279 <literallayout class='monospaced'>
1280 $ sudo service portmap restart
1281 </literallayout>

1285 If needed, enter your host root password in

1287 This sets up a <filename>Tap 0</filename>

1295 Once QEMU launches, you can begin operating
1296 within that environment.
1297 One useful task at this point would be to determine
1298 the IP Address for the user-space NFS by using the
1299 <filename>ifconfig</filename> command.
1300 The IP address of the QEMU machine appears in the
1301 xterm window.
1302 You can use this address to help you see which
1303 particular
1304 IP address the instance of QEMU is using.

1314 Once the QEMU emulator is running the image, you can deploy
1315 your application using the Eclipse IDE and then use
1316 the emulator to perform debugging.
1317 Follow these steps to deploy the application.
1318 <note>
1319 Currently, Eclipse does not support SSH port
1320 forwarding.
1321 Consequently, if you need to run or debug a remote
1322 application using the host display, you must create a
1323 tunneling connection from outside Eclipse and keep
1324 that connection alive during your work.
1325 For example, in a new terminal, run the following:
1326 <literallayout class='monospaced'>
1327 $ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable>
1328 </literallayout>
1329 Using the above form, here is an example:
1330 <literallayout class='monospaced'>
1331 $ ssh -XY root@192.168.7.2
1332 </literallayout>
1333 After running the command, add the command to be
1334 executed in Eclipse's run configuration before the
1335 application as follows:
1336 <literallayout class='monospaced'>
1337 export DISPLAY=:10.0
1338 </literallayout>
1339 Be sure to not destroy the connection during your QEMU
1340 session (i.e. do not
1341 exit out of or close that shell).

1406 Assuming you are connecting as the root

1408 images provided by the Yocto Project, in the

1410 field, browse to
1411 <filename>/home/root/</filename><replaceable>ProjectName</replaceable>
1412 (e.g. <filename>/home/root/hello</filename>).
1413 You could also browse to any other path you have
1414 write access to on the target such as
1415 <filename>/usr/bin</filename>.
1416 This location is where your application will be
1417 located on the QEMU system.
1418 If you fail to browse to and specify an appropriate
1419 location, QEMU will not understand what to remotely
1420 launch.
1421 Eclipse is helpful in that it auto fills your
1422 application name for you assuming you browsed to a
1423 directory.
