#20 Fosphor not working on Pi version

[Ron McGann]

Fosphor block is not working on Pi64_beta23. Throws the following error for all window selections:

Param - Window Type(wintype):
Value "firdes.WIN_BLACKMAN_hARRIS" cannot be evaluated:
type object 'gnuradio.filter.filter_python.firdes' has no attribute
'WIN_BLACKMAN_hARRIS'

Param - Window Type(wintype):
Expression None is invalid for type 'int'

I've never tired on a Pi, but I also wouldn't have expected it to work.

You'd need a GPU w/ OpenCL. Maybe there would be a way to leverage the CPU, but I can't imagine that would perform well.

Maybe this would be an option

On my laptop I've been running it in flow graphs, but that's via a Nvidia 3xxx model. Still, it requires some configuration like Nvidia drivers.

Ah, yes - good point. Not sure I understand why it would be included in the release then.

BTW - dragonos seems to be working brilliantly on Pi4 with both BladeRF and HackRF One.

Thankyou for the feedback .

I think just the standard gnuradio package has it included. If i get a chance id like to see what happens if i try and get it to use the cpu. I dont have high hopes.

Great to hear the bladerf and hackrf are working!
