Hello all,
I am transmitting TAP packets using USRP E310 in network mode. I have a
custom block called "rtag" which gets two TAP interface inputs and puts
these messages to output (it's serializing these inputs). I am tagging
each packet with "packet_len"(beginning of packet) and "tx_eob"(end
Now that I have GR 3.8 built and running, I tried to build gr-display.
from the README instructions:
"""
get the latest code from https://github.com/dl1ksv/gr-display
The build process is cmake based. So change to the code directory.
There
$mkdir build
$cd build
$cmake -DCMAKE_INSTALL_PREFIX= ..
On github in gr-display exists a gnuradio3.8 branch. Try this one.
Now that gnuradio switched to 3.8 I should switch the master branch to
3.8, too.

So I tried re-implementing the gr-dtv Reed Solomon decoder with an
additional output so I could monitor/output the number of errors corrected.
I used gr-modtool, created new block with new name so it wouldn't conflict
with the existing and made sure to update the markup language for the grc
block.
Hi Alex!
Hm, interesting. Would you happen to have the full verbatim error?
As a complete aside:
I know we're not doing any of that consistently in the tree, but
especially when handling things like polynomials "packed" into
integers, and amounts of bits, I always recommend people explicitly use
"
Sure. FYI I'm running 3.7.10here is the error:

Hi,
If you are interested in measuring the number of errors in the Reed-Solomon
block of DTV, you may take a look at our OOT module gr-isdbt (
https://github.com/git-artes/gr-isdbt) which includes modifications to the
RS (and the viterbi) decoder to outputs the BER (but is easily modifiable
to outp
Hi Federico,
would it make sense to merge that extension back to mainline GNU Radio?
Best regards,
Marcus

Hi Michael,
Any update on this? I downgraded my install of uhd and gnuradio as follows
but I have the same error.
Traceback (most recent call last):
File "/home/sumit/Desktop/top_block.py", line 122, in
main()
File "/home/sumit/Desktop/top_block.py", line 110, in main
tb = top_block_c
Wow, that's a pretty old version GNU Radio! Might be worth updating
your Linux distro :)
Anyways, this is strange!
You don't happen to implement a `check_topology` method, do you?
Best regards,
Marcus

Hi,
I think it is very possible to merge them, specially in the RS decoder
which I didn't modify much. The viterbi took me quiet some thinking and
testing, but it's possible too.
If it would make sense, that's another question :-). I use it mostly as
another indicator that the flowgraph is correctl
Hi Volker,
1) What specific URL should I use? I tried:
git clone https://github.com/dl1ksv/gr-display/tree/gnuradio3.8
Cloning into 'gnuradio3.8'...
fatal: repository
'https://github.com/dl1ksv/gr-display/tree/gnuradio3.8/' not found
and also:
git clone
https://github.com/dl1ksv/gr-display/
Barry,
Try this:
git clone https://github.com/dl1ksv/gr-display.git
cd gr-display
git checkout gnuradio3.8
-cp
