+ 1. Q:'''We tried to use the zdc_framework with our code in a 64-bit kernel. The zdc_framework kept saying that the nodes (with the 64-bit kernel) were not on. We didn't have the problem when a 32-bit kernel was used. Could you help us on this?''' [[BR]]
+    A: The problem is most likely related to outdated OMF Resource Controller package on the image. Just upgrading the omf-resctl-5.4 should fix the issue:
+{{{
+apt-get update
+apt-get install omf-resctl-5.4
+}}}
+    Alternatively, one can do the full upgrade:
+{{{
+apt-get update
+apt-get upgrade
+}}}
+    to bring all the packages to their latest versions.
  1. Q:'''We couldn't find the USRP on nodeX-Y. Tried uhd_find_devices, uhd_usrp_probe, and ping. None work. Is it power-on?''' [[BR]]
-    A: The USRPs in ORBIT share power supply with the node so that power-cycling the node will also restart the USRP. Please use '''"omf tell -a offh -t nodeX-Y"''' followed with, after a few seconds, '''"omf tell -a on -t nodeX-Y"''' (just resetting the node will '''NOT''' reset the USRP).

  1. Q:'''So the competition frequency range is only upto 1 GHz?''' [[BR]]
     A: The center frequency for the Preliminary tournament would be between 550-650 MHz.
