Debugger becomes unresponsive when enabling SysTick interrupt
Hi
If BOOT0 is pulled up the bootloader from ROM gets executed. The debugger then has no source code available. How can it follow the jump to the application?
The appclication can be downloaded to flash memory by st-link v2 hardware connected to SWD without using the build in bootloader. But if the application has not defined a debug interface (SWD or JTAG) you will not be able to do this a second time. Then you have to pull up BOOT0 while reset to reconfigure these pins. I can not imagine why a disabled SysTick allows debugging when starting from build in bootloader.
