GPU FFT Error
Posted: Wed Feb 04, 2015 8:29 am
I've tried the demo program as described at http://www.raspberrypi.org/accelerating ... /#comments
But when I run it, I just get the error:
"Unable to enable V3D. Please check your firmware is up to date."
Any ideas?! This is on a B+ BTW.

Code: Select all
root@raspberrypi:/opt/vc/src/hello_pi/hello_fft# ./hello_fft.bin
Usage: hello_fft.bin log2_N [jobs [loops]]
log2_N = log2(FFT_length), log2_N = 8...21
jobs = transforms per batch, jobs>0, default 1
loops = number of test repeats, loops>0, default 1
