I’m attempting to run some of the example rfnoc flowgraphs in Gnruadio
using X410. I keep getting an error that’s similar to the following:
line 114, in __init__
self.uhd_rfnoc_addsub_0 = uhd.rfnoc_block_generic(
RuntimeError: Cannot find block with ID: AddSub Device/Instance: -1/-1
I’m using the latest Gnuradio v3.11.0.0
Does anyone know what that means and how to fix?

Likely because the image running on your device doesn't have that block
in the FPGA image. The "basic" images
don't have much "wired in" to them.
Use uhd_usrp_probe with the device and see which RFNoC blocks are in the
image.
You'll need the ability to generate your own FPGA images to add in RFNoC
blocks of your choosing...
