I am using Keil 4.72, STM32F100VB with STLinkV2 for debugging purposes. When system is in debug mode, it looks perfectly but if I flash the chip and run in non debug mode (with SWD connected or removed), firmware do not work properly.
Does anybody seen symptoms like this, I do not change any setting of tool like optimisation etc.
Thanks in advance for any hint to look the problem.
