Board: PYNQ Z2  
Software: Vitis 2023.2, Vivado 2023.2  
The deployment is stuck at recvchannel.wait().

The code is about creating Hardware Accelerator for CNN Algorithm.  
The code can be found at : [GitHub - kushaanbhat/Hardware\_Accelerator\_for\_Object\_Detection](https://github.com/kushaanbhat/Hardware_Accelerator_for_Object_Detection)  
I tried fixing TLAST bit issue still got the same result.

Snip of the error
