KeyError: 'power1'

[GGGGGGGG5566]

Hello SkyNet,

I want to deploy the code on Ultra96-V2.
I started over and built the bitstream and weights from scratch

After finishing building the bitstream and weights, I changed the file name to "SkyNet.bin", "SkyNet.hwh", and "SkyNet.bit", and then ran the script "SkyNet.py" provided by the team.

But I always got the message KeyError: 'power1'

I tried to print out pynq.get_rails() and I only have these followings

{'in1': Rail {name=in1, voltage=Sensor {name=in1_voltage, value=1.193V}}, 
'in2': Rail {name=in2, voltage=Sensor {name=in2_voltage, value=1.797V}}, 
'in3': Rail {name=in3, voltage=Sensor {name=in3_voltage, value=0.844V}}, 
'in4': Rail {name=in4, voltage=Sensor {name=in4_voltage, value=0.852V}}, '
in5': Rail {name=in5, voltage=Sensor {name=in5_voltage, value=1.798V}}, 
'in6': Rail {name=in6, voltage=Sensor {name=in6_voltage, value=1.794V}}, 
'in7': Rail {name=in7, voltage=Sensor {name=in7_voltage, value=0.842V}}, 
'in8': Rail {name=in8, voltage=Sensor {name=in8_voltage, value=0.841V}}, 
'in9': Rail {name=in9, voltage=Sensor {name=in9_voltage, value=0.844V}}, 
'in10': Rail {name=in10, voltage=Sensor {name=in10_voltage, value=1.796V}}, 
'in11': Rail {name=in11, voltage=Sensor {name=in11_voltage, value=1.092V}}}

No "power1" is in pynq.get_rails().
Could you kindly suggest which part I might go wrong so that I could fix it?

Thank you.

Hi,

Thanks for your interest.
The pynq.get_rails() is just about measuring the board power consumption. If you don't need it, you can actually remove the power related code, eg. line 172, 173, 194, etc.

If you do require the power measurement, maybe it is because of the board version, since we were using ultra96-V1.

Thanks,
Cong
