The ``sdp.set_defaults()`` command, followed by ``sst.set_defaults()`` / ``xst.set_defaults()``, should reset that device to its default settings, which should result in a working system again. If not, or if the default configuration is not correct, check the following settings:
- ``sdp.TR_fpga_mask_RW[x] == True``, to make sure we're actually configuring the FPGAs,

Are you sure? If ``sst.nof_packets_received`` / ``xst.nof_packets_received`` is actually increasing, the packets are arriving, but are not parsable by the SST/XST device. If so, see the previous question.

Many settings need to be correct for the statistics emitted by the SDP FPGAs to reach our devices correctly. Here is a brief overview:
