Hello,
I've been having a strange problem with the gr-fec block, and I think it may be
connected to other issues I'm having. I'm running a flowgraph on the E310 using
the LDPC Encoder Definition (via Generator), LDPC Generator Matrix, and FEC
Async Encoder blocks and it has been running fine for a few months. For another
block, I needed to update the Volk library because I wanted a new kernel, but
when I did so a couple of things started to break.
I thought this was due to my update of GNURadio/Volk, but I have reinstalled
the SDK as well as UHD and GNUradio from source (using these instructions:
https://files.ettus.com/manual/page_usrp_e3x0.html) and I still get the same
problems. I am using UHD version 3.9.2 (I need to for other compatibility
issues, this has not given me trouble in the past) and GNURadio 3.7.11.1 (The
version I was using when everything worked). My cross compiling also seems to
be working fine, I get no errors in my cmake or make process. I am using the
fpga files and SDK from here:
http://files.ettus.com/e3xx_images/e3xx-release-4/
In the following gdb backtraces, I've built both GNURadio and my OOT module
with -DCMAKE_BUILD_TYPE=Debug.
Error 1:
When I kill a flowgraph with the LDPC Encoder in it, I get either a segfault
or an invalid pointer error when the program tries to call the destructor of
ldpc_gen_mtrx_encoder_impl.cc. (full backtrace in
message_port_in_not_working.txt)

Error 2: I have my own message block, which has suddenly stopped working, the
flowgraph does not recognize the input port (called pdus_in) and the backtrace
traces back to a boost header file. (full backtrace in

I've rebuilt the SDK multiple times, I'm really not sure what could be giving
me these errors.
Thank you,
