[srslte-users] Building srsLTE on RasPi 4 Buster...

Hi,
I did not try for some time, but I will test these days if it still works with my RasPi 4. My tests showed that not more than 5 MHz bandwidth work, as the CPU power of the little thingy is the limitation.
Ralph.

Andre,
Thank you for the background information; that's good to know.
Today I rebuilt the entire RPi4 from a fresh Raspbian image and tried the same experiment with the BladeRF. I ran into the exact same issue.
I guess I'll put this whole project back on the shelf until the next release and see how that goes.
Thanks again for your help,
James

Hi James,
I am afraid I can't really help you on this at the moment. There are
people (e.g. Ralph) who have successfully used the Rpi4 with the eNB,
but we haven't really tried that ourselves.
We've changed many things regarding timing in recent past and those will
be made available in the next release. So hopefully things will be
easier then.
Cheers
Andre
