I saw some tutorials on AXI GPIO, but I am still having a hard time connecting the IP to my custom IP built in HLS (with Vitis HLS).
In particular, I have a block design which I am attaching below, where the IP called
linear_multistep_0 is my HLS IP. It works fine, I have already tried it with Python, I have tested it and it works fine.
Right now though, I just start the IP with Jupyter Notebook, hence I need a laptop and the Pynq connected through Ethernet. I would like to be able to run the script just pressing a button, i.e., the final result should be a script loaded on the ARM CPU and the ability to start it with just a button. This is a first trial to eventually run a bitstream which loops whenever the board is connected to a power source, without the necessity to start everything.
I understand that using a button would still require me to start the python script with the host, to start listening to the interrupt. In fact, I still don’t know how I could achieve my last goal, but let’s focus on one step at a time (if someone can give me an overview would be amazing though).
Thank you so much in advance for your help.
I figured that AXI GPIO couldn’t get synthesized just beacuse Vivado couldn’t find my custom IP. Here’s below the design with the AXI GPIO. It works without any problem and I also could run the core with buttons through this script (I know it’s not clever but I just wanted it to work):
while (not btn.read()): if (btn.read()): iterations = 10 time = timeit.timeit(lambda: linear_multistep_fpga(), number=iterations) print('Average of ' + str(time/iterations) + ' seconds') print(True == np.allclose(X_FPGA[:], X_CPU[:], rtol=0.00000001)) while (btn.read()): pass
Still, can anyone tell me how to implement something that doesn’t need a host to run? Thank you so much.
Here’s the block diagram:
