GPU FFT Error

[markvr]

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."

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
root@raspberrypi:/opt/vc/src/hello_pi/hello_fft# ./hello_fft.bin 8
Unable to enable V3D. Please check your firmware is up to date.

root@raspberrypi:/opt/vc/src/hello_pi/hello_fft# rpi-update
...snip...
 *** Your firmware is already up to date

Any ideas?! This is on a B+ BTW.
