Pc104
See pc104/Archive for information about previous setups.
The pc104 CPU board is located into the iCub's head and it runs a full (read/write) Debian distribution that boots from a USB pen drive.
Booting and mounting
During boot, the pc104 does two things: 1) it loads a Debian Live USB Flash Drive with Persistence; 2) it mounts remote NFS shares from the iCub laptop.
USB Flash Drive
With respect to the standard image provided by the official iCub support, our configuration differs in the following files:
.bashrc_iCub /etc/network/interfaces /etc/hosts /etc/fstab /etc/rciCub.d/mounts.list /etc/rciCub.d/S90_mount-remote-fs.sh /etc/timezone /etc/resolv.conf /etc/udev/rules.d/70-persistent-net.rules /etc/default/ntpdate
The mounted volume contains the yarp and iCub repositories (both code and binaries) and configuration files. The binaries are located in the respective build-pc104 subdirectories.
Software

sudo apt-get install libraw1394-dev libdc1394-22-dev
- yarp CMake configuration

- icub-main CMake configuration

- yarp configuration
yarp namespace /icubyarp conf 10.10.1.53 10000(yarpserver runs on iCub laptop)
The last command writes the information of the YARP server located on iCub laptop into the file specified by yarp conf, which is typically /home/icub/.config/yarp/_icub.conf. Warning: that command overwrites previous content.
- tuning and optimization
- make sure that
CMAKE_BUILD_TYPE=Releasefor both yarp and icub-main cat /proc/sys/net/core/rmem_max// should return 8388608
Updating
In addition to yarp and icub-main, icub-firmware-shared must also be updated (these are scripts, not the firmware itself). In order to update the firmware, use the binaries in icub-firmware-build and follow the official iCub manual.
