Expand the size of the matrix

Hi, I tried to change the dimensions for matrix A and B into 1000*1000, and I just changed the size of matrix in mmilt.hpp and sharedmem.py. It did not work, the result of the matrix was wrong. Here are the codes I changed, the board I used is PYNQ-Z1. Can you tell me what else should I change, thx.
in mmult.hpp
// Dimensions for A and B (which determine C)
#define A_ROWS 1000
#define A_COLS 1000
#define B_ROWS A_COLS
#define B_COLS 1000
in sharedmem.py
__MMULT_A_SHAPE = (1000, 1000)
__MMULT_BT_SHAPE = (1000, 1000)
__MMULT_C_SHAPE = (1000, 1000)

I also want to know if i change the type to float would the ip work correctly?

Matrix_mmult

Hi, i am new to pynq board and i want to run matrix mult on ultra96v2 pynq board.
I have to write the overlay using vivado hls and vivado to generate tcl and bit file.
But i meet some problem of this.
Can i use only mmult.cpp file which includes mmult.hpp to run C synthesis and export RTL using Vivado HLS?
Or i have to use mmult.cpp, mmult.hpp and main,cpp in Vivado HLS?
Any advice will be aooreciate!!!
Thanks a lot!

AttributeError: 'NoneType' object has no attribute 'get'

I am trying to recreate your work but I get the 'AttributeError: 'NoneType' object has no attribute 'get'' error. I have copied the complete error in the message. I am using PYNQ Z1 v2.4 and I used Vivado 2020.1 release.
I have the .bit, .hwh and .tlc files in my overlay folder.

I have also tired with only the .tlc and .bit files which causes another problem:

UserWarning: Users will not get PARAMETERS / REGISTERS information through TCL files. HWH file is recommended.
warnings.warn(message, UserWarning)

which in turn leads to:
