Hi again, Some more info that I've gathered in the meantime on the issue: - the crashes seem more related to the fact that I've been dumping the retrieved I/Q pairs on file, so we could leave it out for the moment; - what I did to test whether the FIR is working as expected or not, is to retrieve its coefficients via the get_filter() function, cast the filter_info_base pointer to a digital_filter_fir pointer using a dynamic_pointer_cast, and then invoke the set_taps() function setting all coefficients to zero. If I re-read immediately the coefficients, they're all zeros as expected. However, reading them later shows that they're not zeros anymore. Indeed, given this configuration I should receive an identically null signal, but the signal seems to be untouched with respect to the "standard FIR setting".
I could alter the UHD library (or the AD9361 driver) at "low level" to make it behave as I expect, but I would rather stick with a more gentle approach. Any idea? Thanks again! RH
