Try decimating after the filter, before you start computing log10 at the input rate.  There's no need to do those calculations at the original

  sample rate once you've computing complex-to-mag**2 and filtered.

Tried that, but still ocurring overflow.

Another thing I had was that on my computer I was using a 

complex to mag^2 -> single pole IIR filter -> log10 -> multiply const (10)
to measure the signal strength

that is also causing overflow on the single board computer. If I put a RMS
block instead, no overflow occurs.
