    Hi, I'm using Embos for Cortex M and Keil IDE to realize a firmware for K60FN1M0xxx15. When program calls OS_Start function, OS_Error is called with error OS_ERR_STACK=0x78 and the K60 is reset. if I use breakpoint in OS_Error, I see that the last called function is OS_ChangeTask_VFP(). In startup code, I defined: Stack_Size EQU 0x00000400 Heap_Size EQU 0x00000200 I tried to increase the size of stack, but the error remains. How can I resolve the problem? Thanks in advance Best regards Veronica
