Hello, I am sharing how i did it. I set lo_offset=20e3 then i am changing
center_frequency. Also thank you Marcus, have a nice day.
```
self.uhd_usrp_source_0.set_center_freq(uhd.tune_request(center_freq,
rf_freq=center_freq-lo_offset,

Hi Marcus,
Thank you for your help.
I set it in the .bashrc file before.
I exported it and now it's working.
Best regards

Hi USRP users,
I am currently developing an OOT RFNoC module.
When I tried to build a custom image, it gave me errors as below.
I checked the python path, and it seems fine.
Is there anyone that has any idea of the reason for this?
I am using n310 with uhd v4.2.0.0.

I'll try and play with the network parameters to see if anything changes.
The large packet strategy doesn't seem to be the best approach for what I am
doing anyway, since I cannot reach 2048 samples.
I'll also try to modify the K1N block to me more like a Keep-M-in-N block.

Hi,
Sorry for reviving this thread, I still have found no solution to this problem.
I moved my application from python to c++ for performance reasons and the issue
is somehow different.
I found this old thread about the fft length on rfnoc:

Hi Henry,
I am unsure if you tried with an "LO offset" or if you just changed your
center frequency. Changing the center frequency will not avoid the
problems which can occur at the LO frequency.
There are two ways you can create a CW signal that is offset from the LO
frequency. You can either c
Hi Lorenzo,
Regarding the SPP=364, this sounds like it is being set according to your
Ethernet transport MTU. Sometimes the NIC defaults to MTU=1500 rather than
9000. If I am right it means that even if you created a graph without K1N,
you would still get SPP=364. If the Ethernet MTU is set to 900
