Two USRP2 sync, VRT firmware

I am trying to synchronize two USRPs using VRT code.
However, I found the firmware for VRT branch is no longer exist(the
link is broken)

Can I find the firware and fpga image from somewhere else?

Another thing is that.
I think no one successfully synchronized USRPs using MIMO connector.
That is why I am trying to use VRT code.
What I am trying to do is simply synchronize two identical transmitted
packets from two USRPs.
Any better idea?

I had accidentally deleted these files (long story/bad monday). You can
build them from the vrt branch. However, I highly recommend that you use
the UHD for synchronization of usrp2s. The vrt branch is experimental
and will not be maintained.
