starting the debugger : (Read)Failed determine breakpoint type

[Evan .1]

When I start the debug environment in stm32CubeIde. I got the following error message:

It look like your gdb server from 2019 does not know the STM32H7A/B release in 2020. Check for updates.

I did check for updates. And I got the latest version.

STM32CubeIDE

Version: 1.3.1

Build: 6291_20200406_0752 (UTC)

OS: Windows 10, v.10.0, x86_64 / win32

Java version: 1.8.0_202

How was this problem solved?

I have the same problem starting to debug with the Nucleo-L053R8 with STM32Cube v.1.5.0

[PVand.9]

I was able to get one step further:

It seems that STM32CubeMX had failed to create a directory called "startup" in the directory "core" as it did in earlier days. (or my settings must have changed since)

By copying this directory with the one file in it from a previous program (and erasing the two lines that created errors on compiling), the program starts working, but I'm still not able to pause or step it.

The debugger seems to pause, but the real program on the Nucleo keeps running (flashing leds f.e.)

[PVand.9]

I continues by choosing the OpenOCD as debug probe instead of the ST-link GDB server (in debug configurations - tab debugger). Here the debugging seems normal.

The "Startup" directory is used by the vendor code. Did you write your own Makefile and startup code?

I just had the same problem. I wrote my own Makefile + startup code. (Cortex-M0+)

I also noticed that if i use the vendor code, i don't get this problem.

I tracked it down to how I link.

I had to remove the -Wl,--gc-sections from my linker.

Interesting, because the vendor Makefile uses -Wl,--gc-sections when linking. The actual answer may be something else, but this worked for me.

Here is how I link.

MACH = cortex-m0plus

FPU = -mfloat-abi=soft

LIBGCC = -lgcc

LIBMATH = -lm

MAP = -Wl,-Map=final.map

LDFLAGS = -mcpu=$(MACH) -mthumb $(FPU) -T linker_script.ld $(MAP) -nostdlib -Wl,--start-group $(LIBMATH) $(LIBGCC) -lc -lnosys -Wl,--end-group

$(EXECUTABLE_WPATH): $(OBJ)

$(CC) -o $@ $^ $(LDFLAGS)
