Application for BeagleBone

Hi,

I am Ana and i study engineering at Electronics and Telecommunication in Romania. I wanted to inform you that for my diploma thesis i made an application for Beagle Bone using the specifications from the standard IEEE 1588 version 2 Annexa F. I am really content with the results as i managed to synchronize two Beagle Bone devices by generating on each of them one signal with the frequency 1Hz. By doing so, the signal from the slave device is synchronized with the one from the master device.

I also wanted to thank you for the documentation available on the site.

    Hi Ana,

    nice to hear your success story. Do you have that work documented on the web somewhere? I think many people would be interested in this and could learn from it.

    If you have no resource for publishing you could use the TI processor wiki.

    Regards.

    Hi,

    I'm currently editing my paper, which is due in July and as soon as i finish it, i will most probably upload some of my work using the TI processor wiki. I can tell you right now some of the results: i had two Beagle Bone devices, one was running as slave and the other one as master. After generating on each of them one signal with the frequency of 1Hz i measured the distance between master's slope and slave'slope using the oscilloscope. The variation in time (the time interval was considered 2h and 45 minutes) was equal to 1,45 us/s ~ 1,5 ppm. After running PTP, i measured again the variation in time (the time interval=21h) and it was equal with 21,3 ns/s ~ 22 ppb, which means better stability.

    Thanks,

    Hi Ana, I am considering similar project. Would you be able to share more details?
