Hi!
I start to learn STM32 (STM32F103GB on MCBSTM32 board, example project "blinky") and have faced with following problem: I can't insert breakpoint in C and "insert/remove breakpoint" button on Debug Toolbar always disabled. The only way to define breakpoint is double-click on grey window bar in disasm window. Program executed, breakpoint in disasm occurs... but what can I do to use breakpoits in C?
Regards, Ilya.
It's so strange... I try to use ST-LINK as in-circuit debugger and it's correctly work with JTAG interface. But gives errors with SWD when I try to enter a debug session. These errors displays in windows with "OK" button only. First: "internal command error", second: "error while attempting to write 16 bytes to 0x1ffff800". And at result situation like with J-Link - program code executed, breakpoints avaliable only in disasm window.

The text from command window:

In your project options (Alt+F7) - Output tab: Debug Information should be checked - Linker tab: Misc. controls should contain --debug With these options set, rebuild your project and see if you can place breakpoints in your C code
I added printscreens with these options (see at link for previous pictures). The result remained the same...
Are you able to set breakpoints if you debug using Simulator? (In the Debug tab of your project options it is from left)
Thank you for your attention! The problem solved.
Shouldn't you tell how you solved your problem?
Reinstall Keil and jLink drivers... That's all.
