You do need to remember to bit-reverse the data (from a rbf or pof) before writing it to the epcq. This is all easily verified by reading what the altera tools write to the epcq. I do wish Altera had documented the 'remote update' block as a 'reconfigure from epcq' block and then explained how it could be used for user/factory (etc) images. I've managed to correctly write the epcq, but can't manage to request the fpga reconfigure itself (works ok on power up). This might be because I've added the jtag<->epcq block in order to expose the epcq interface.
