Re: [Discuss-gnuradio] updating all of pybombs

That indeed is the nuclear option. If you want to scale it back to "daisy cutter" you can remove the src directory and inventory.dat... and capture the debug output when the build breaks. On Thu, Nov 12, 2015 at 8:02 AM, Simon Kennedy wrote: > A couple of days ago I ran ./pybombs update and it fa

You can run pybombs with extra verbose flags (I usually recommend "-v -v -v") to see what it's doing, but as part of the update process it'll clean the source directories. There's also "./pybombs inv" to see what pybombs thinks is installed. I tend to wipe my target directory and just start fresh

[Discuss-gnuradio] Bug with set_taps in pfb_clock_sync

2015-11-24 Thread Richard Bell
I think I've come across a bug with the pfb_clock_sync blocks set_taps implementation. If I change a parameter in python that causes a change to the filter tap variable being fed to the pfb_clock_sync block, which then requires pfb_clock_sync.set_taps() to be called, the program will error out with

Hi Ekko, really, use GDB, not Pdb. Just "run" your program, than "backtrace"; stepping through it is really really tedious, and isn't really extremely helpful unless you know intimately where to look. As Tom mentioned, the debugging (and the GDB) tutorial will be helpful. Best regards, Marcus O

We're short on information to actually determine what's wrong here. It looks like you're still using pdb, but I see different output/problem areas from your screenshots. The first one looks like it crashed in tb.start, and the second one looks like it crashed just creating the channel model block.

Hi Martin, I think you got it right to insert the tag at least if you have a packet_len tag (and maybe MIMO). There might be a performance issue, because we get buffer underruns above 2 MHz sampling frequency, while not getting anyone with continuous streaming. Otherwise, any solution leading
