Could you share `bitfile.hwh`?

Hi, @hqjenny

Thank you very much for sharing your great work!!

I'm try running CoDeNet on ultra96v2 with sw/codenet.ipynb. The following error occurs when invoking the accelerator, meaning 'batch.hwh' is required. I really appreciate it if you would share it, so that I could run CoDeNet on FPGA without synthesizing with vivado.

Thanks in advance.

accel = CoDeNetAccel(MAX_D=128, MAX_IC=1024, MAX_OC=1024, PA=16, PE=16, bitfile="batch.bit")
x = np.random.randint(256, size=(1,64,64,32))
y = accel.CoDeNet(x, w2=False)
accel.print_stats()

Hi @in-die-nibelungen, Sorry for the late reply. Could you try downloading the bitfile folder here? And upload the folder to your ipython notebook?

If that does not work, we can try generating the bitfile.hwh for you.
