Problems with a simple floating point adder overlay on ULTRA96-V2

[Nidhal_Bj]

I have made a simple adder on Vivado HLS with float input and outputs. On Jupyter Notebooks in ultra96-v2, I get the following errors.

How can I fix this problem ?

Hi @Nidhal_Bj,

Please have a look at this post

As you noticed, MMIO doesn’t support float. You need to manually ‘pack’ your float into something that can be written to the IP, and do the reverse if you need to read back the result. You can use these types of techniques: https://stackoverflow.com/questions/23624212/how-to-convert-a-float-into-hex Cathal
