I try to run a very simple program on ZCU104 to test the PYNQ design process, my program stuck there when I trying to start the overlay, here are the details:
1.Evaluation Kit: EK-U1-ZCU104-G-ED
2.1 In Vivado HLS, write a basic program, which only reads in a matrix with 28*28 8-bit elements, change the matrix elements value, then return the revised matrix.
Here is the HLS function code:
2.2Make the HLS program into IP, use Vivado to start an IP block design(where I think the problem located in?)
When validating the block design, the memory address cannot be located correctly.
I have to choose “Auto Assign Address” in the address editor, but some ports are still excluded and left critical warning here.
2.3 I put the overlay bitstream file (design_1_wrapper.bit) and hardware file (design_1.hwh) on the ZCU104board.
3.The PYNQ code in Jupyter notebook:
My program stuck hanging here:
since ADDR_AP_CTRL always be 0.
I do a small test, assign values to different IP addresses.
For those pre-claimed registers, no matter what value I assign, the value is always 0, I guess this is the direct cause of the problem, but not where I should fix it.
For the self-claimed memory address, I can correctly write in the value(cc=0x81=129).
.Can anyone give me some advice? A thousand thanks.
