Schuduler not running

Hi, I’m trying to run FreeRTOS on my custom board with AT91SAM7X and Crossworks. Simple LED switching without RTOS works. With scheduler it only works only in debug mode and only when I use step mode(line by line). Could it be hardware problem? Instable clock, PLL? I’ll appreciate any help.
