Frequently Asked Questions
about the White Rabbit Starting Kit
Starting Kit Hardware
Does the USB cable to the micro B connector on the spec board have to be connected all the time? Or is it only required at some point during the installation?
We strongly suggest you to keep the USB cable to the micro B connector
at this moment, because it is the easiest way to configure the SPEC
(wrpc shell).
Some other solutions exists but we would not recommend them for
starting.
Do I need to connect the external power supply connector when used in a PCIe slot?
No the power supply is not necessary while connecting through the PCIe slot. The board gets its power from the PCIe card edge connector. This exernal connector is only used in stand-alone applications where the card is not plugged into a PCIe slot.
Starting Kit Software
The starting kit is based on Ubuntu. How can I use it with Scientific Linux?
The commands to execute in order to update the kernel using scientific linux (you need at least the 2.6.36 to compile the starting kit) are:
rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm
sudo yum --enablerepo=elrepo-kernel --skip-broken install kernel-lt kernel-lt-devel kernel-lt-headers
You can have more information on how to do this by browsing the ELRepo Project
After this you should reboot your PC with the new kernel source and start from section 3.4 in wr-starting-kit-v1.0.pdf
