Getting stuck in HALT();while configure the UART in xml

Question

Hi All, 
 I'm working on PK- S5D9 dev kit, I have added the UART configuration Once properly configured just call the uart_main(); in main_thread_entry.c. 
 Most of the time it gets stuck in HALT(); in MallocLock(). Sometimes I'm able to see the output in the terminal. I have no idea what's happening in my code. Even though I have deleted the project and import again facing the same issue. 
 What's the issue? If I want to test uart do I have to create a new thread in the main file or just call the uart main in main_thread_entry();? 
 I have attached the latest code which includes uart configuration. 
 Kindly help me out with this issue. 
 Thanks in advance,

Hello SD, 
 Sorry for the late reply 
 The issue you face seems to be unrelated to the UART and is concerned the malloc function. Try to remove it from your code if possible to check if the issue is gone. 
 As for the UART communication, it depends on the architecture of your program. If the main loop of the main_thread_entry is not overloaded, you can put your uart_main function inside it. Otherwise you better make a separate thread and provide means of communication between the UART and main threads.

Hello SD, 
 Actually pins P511, 512 you are using for UART communication are merged with the LCD touch screen 
 
 You can check what pins are occupied in the PK-S5D9 board in the User's Manual: www.renesas.com/.../promotion-kit-s5d9-pk-s5d9-users-manual
