IWR1443BOOST: using SPI

Hi,

I am tying to use SPI to send detected objects to an external MCU. I have modified the out of box demo to use SPI. however, the received data is not as expected.

for example, i want to send 11 as below

But when i use printf to print the received data on the MCU i get this 

these numbers repeat forever. 

did i miss something?

and what changes should i make to send the detected objects?

Code for the MCU :

6327.main.c

Thank you,

Abdoulah
