AM2634: DebugP_log("") causes issue on SPI

Part Number: AM2634

Tool/software:

Hi Team,

I was trying to have SPI communication between two AM2634 microcontrollers. I have intiated communication between both of them and printed some debug logs using DebugP_log() to validate sent and received messages. But slave controller gets stopped after some packets sent. If I reduce text in DebugP_log() it works fine for more no of packets. 

Please let me know, why DebugP_log() is having impact here.

Also, please give the spi configurarion details for MASTER and SLAVE. So as I will verify it.
