STemwin Hard Fault

Question asked by alexey.seregin on Jun 8, 2015
Hello. I use STemWin_Library_V1.1.2. Processor STM32F103, IDE IAR EWARM 6.50. When executed GUI_Init() processor rush out in HardFault_Handler(). I found in debugging mode, what it happened when executed assembler command BLX R1 (R1=0x08004C30), or the memory address on jupm command out of processor FLASH regions. But sometimes in debugging mode GUI_Init() execute, and after GUI work OK. Change project option, stack size, GUI memory not helped. Programm still non-forking. What is the problem may be? Thank you.
