Re: [Discuss-gnuradio] Segmentation fault

you said to use sdk,is it mean cross-compile on my pc for e310,then run on e310?

Exactly :)

could you send me a clearly tutorial about how to use sdk on linux pc with USRP e310,so i can handle the problem by myself,

Sure!
Here's the E310 manual:
http://files.ettus.com/manual/page_usrp_e3x0.html
See the section on about SDK usage,
http://files.ettus.com/manual/page_usrp_e3x0.html#e3x0_sdk_usage

For GNU Radio out-of-tree modules, follow the same instructions as given for GNU Radio, which means that you should use the same toolchain file with -DCMAKE_TOOLCHAIN_FILE

Best regards,
Marcus

thank you, marcus 

what is the max bandwidth of usrp e310 just use the arm of e310,no 9361

for example the max throttle value in a simulation grc(no uhd)

i have google for this ,but got no answer.

there is a additional blocks in flowgraph 

i follow the tutorials

http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_C++

write the block my_qpsk_demod,

use cmake ../

make 

make install 

to compile the block

you are right ,there is 180 message of command 'bt'

i only show you the nine of these,

marcus said that SIGILL is not the segfault.

the message is too much ,i am using X11+putty with e310 ,i do not konw how to copy it out ,

and my gnuradio version is 3.7.7

thank you

I think there's some lines missing from your screenshot. Instead of a screenshot can you just copy and paste all of the text that you get out? Also, it looks like you're in the middle of the tutorials. Does the flowgraph contain any blocks that you compiled in addition to what came on the E310 image? If so, how did you compile them.
