I use MDK 5.12. (STM10x packet loaded.) My jtag device is ST-Link /V2.
I don't see any problem with compiling and flash programming with JTAG (SWD) device.
But in debug mode;
My codes not running with F5 key.
But codes working step by step with F11 and F10 keys.
Before I use MDK5.11 i dont see this problem.
Why F5 key is not functioning.
I found the problem.
I kill all breakpoints. Now F5 key working.
