Pc104

See pc104/Archive for information about the previous setup with the read-only pen drive.

The pc104 CPU board is located into the iCub's head and nowadays it runs a full (read/write) 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) which contains the yarp2 and iCub repositories.

Repositories on icubsrv laptop

Note that the icubsrv laptop has 2 locations for the repositories:

• /exports/code-64 for the laptop itself (compiled for 64bit, rarely used)
• /exports/code-pc104 for pc104 (compiled for 32bit, this is the one that is actually used)

Updating the repositories

First method: from a pc104 console, normally update and compile the repositories as if on a normal machine - see RobotCub software for details. Note that you after compiling iCub you must type make install_applications as well: this will copy files from $ICUB_ROOT/main/app/robots/iCubLisboa01 to $ICUB_ROOT/app/iCubLisboa01 (check that the new versions are effectively copied).

If the above method fails for any reason (old version of svn, internet problems with DNS or NTP, etc.) you can use the following workaround:

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)
