Hi Louis, I have the same problem of "roach & adc sampling rate". We want to use ROACH as a holography correlator,but the sampling frequency is too high. After we reset the MSSGE block clock rate to 50 MHz, and also used the method you have been used(change all of the instances of 'HIGH' to 'L

In our R2 systems, we have the following kernel: root@vegasr2-2:~# uname -a Linux vegasr2-2 3.7.0-rc2+ #20 Fri Jan 4 18:04:26 SAST 2013 ppc GNU/Linux I'm pretty sure the Roach-2 kernels are all 3.x. Can you get a checksum (md5sum) of the uimage? I think you have the right one, but it may be too
