Hello. I am new to pynq. Trying to transfer arrays between PS and PL on Pynq-z1 board.
The program is a small neural network. I am imitating the writing from an online tutotial:
For my case, the function input is a (13,) shape float array. The output is a (2,) shape float array. Basically, it is a small neural network input and output.
The neural network is generated from the tool called ‘hls4ml’ that converts a keras model into hls code.
The generated code uses ap_fixed as input and output and I am trying to send data as float arrays and then convert to ap_fixed for generated code to run.
So now I have passed simulation, generated ip and bit file. From the notebook file, seems that it stucks its asterisk at dma output receiving step:
Wondering if it has anything to do with the data type conversion or some other reason?
I have attached the program files and block design.
