Pc104

See pc104/Archive for old information.

The pc104 CPU board is located into the iCub's head and it runs a full Debian distribution that boots from a USB pen drive.

Booting and Mounting

After booting, the pc104 mounts a part of the hard-disk of icubsrv (the Dell XPS laptop, IP address 10.10.1.51).

After that, it runs the scripts that are found in icubsrv's /exports/code-pc104/pc104/hooks directory. You can use those scripts for making some configuration permanent on pc104 and/or to run programs. They set up the yarp namespace, configure the keys for passwordless log-ins, etc.

Repositories on icubsrv laptop

Note that the icubsrv laptop has 2 repositories:

• /exports/code-64 for the laptop itself (compiled for 64bit, rarely used)
• /exports/code-pc104 for pc104 (compiled for 32bit)

TODO: verify if the following instructions are still current

Therefore, if you want to update the repository used by pc104, you need to:

1. open a pc104 shell window
2. open an icubsrv shell window
3. on icubsrv: svn update /exports/code-pc104/yarp2 and /exports/code-pc104/iCub (for now we need to do this from icubsrv because the version of svn on pc104 is too old)
4. on pc104: cmake, make in $YARP_DIR (the files are physically on icubsrv, but we need to issue the command from pc104 to obtain 32bit binaries)
5. on pc104: cmake, make, make install_applications in $ICUB_DIR (the files are physically on icubsrv, but we need to issue the command from pc104 to obtain 32bit binaries)

About the hook scripts

The common version of the hook scripts is located in the RobotCub repository, under /usr/local/src/robot/iCub/pc104/startupscripts/opencall/hooks (available, for example, on icubsrv). The procedure is to copy them to icubsrv's /exports/code-pc104/pc104/hooks and then to customize VisLab-specific settings there.
