stalled on bus operation while using NullOS

Hello! I am trying to build the sample code for Mifare Classic project imported from CLEV663B-LPC1769_NFC_Reader_Library without using FreeRTOS. I have disabled the macro definition FreeRtos in nxp_build_app.h and enabled NullOS macro. When I start the debug session, the code starts executing but stops after a while and a message is displayed as "stalled on bus operation". When I checked the "CLIF_IRQHandler function I came to know that it is executing only once and then it gets stopped, but while using FreeRtos the irq handler is executing timely and continuously. This must be the memory issue while using NullOS API but still couldn't able to resolve it. If anyone could guide on this if I am missing out something, please suggest.
