Hi The nice thing about PCI is that you can tie it tightly to the core time wise. Not so easy with USB and all of it's layers.

Hi I had a nasty suspicion that was the case. So now it's either get another 15 45xx boards or figure out another way to do it.

Hi My understanding is that the precision time stuff is specific to the 45xx boards. The "magic hardware" that does the time stamping is not present on the 55xx boards.

Specifically kernel config at this point; the documentation is kind of vague on: CPU_GEODE CPU_SOEKRIS CPU_ELAN Specifically looking for a high precession timing application for a UT+ GPS clock.
