I'm a bit confused about the rfnoc siggen packet size option is doing. I am
trying to incorporate the siggen block into one of my designs, but it doesn't
work right. If I set packet size to 1, things aren't working right.
So I change my packet size to something like 256, setting my other blocks to
the same. GRC doesn't want to run it because siggen's output doesn't match the
others, but that is fine. I press F5 to build, then F6 to run it. The problem
is that it won't run because:
ValueError: itemsize mismatch: uhd_rfnoc_FIFO1:0 using 2048, time_sink_c0:0
using 8
For some reason, the XML doesn't handle changes to the packet size. I tried to
make the change myself, and it runs, but now nothing seems to be exported.
When I try to use the rfnoc_siggen example, it seems to hang now. I get 'D'
and "overrun on chan 0" over-and-over and GRC hangs.
Something is special about siggen, but I can't figure out what.
