If I create an STM32CubeMX project, what is the easiest way to enable semihosting to use printf etc.? You don’t get the options for newlib-nano, generate system call stubs etc. with this project type

Thanks

 

EDIT: totally forgot I made a simalar post the other week, saw your reply and installed the 4073 build, thanks for that!

After installing that, if I enable Support Semihosting, I can include stdio and printf works, but if I enable fast semihosting I still get the errors about _sbrk etc. With both enabled I get the “multiple definition of _isatty” error like in the tutorial, so I will keep this post for that.

Found a GPO to allow creation of symlinks, and it’s working. Thanks again

[dave93cab]

That worked but I am assuming that running VS as Administrator is not usually required? I will look into it further, thanks for the help

[dave93cab]

There’s not much in the log when I try to build it

Ah ok so when I created a new project without ccache enabled I see the cyan, and that does export the command to batch file. I was clicking on the red error line, there is no cyan when ccache is enabled

[dave93cab]

Where does the dump to batch file save the file? Doesn’t appear to do anything and I checked in the project folder. Thanks

Wasn’t using the ARM toolchain, manually selecting that fixed it.

 

EDIT: no it didn’t, sorry. will follow your advice above

Did you install libusb driver for your debugger

[dave93cab]

FYI updated to 20190603 ESP32 debug package and it doesn’t work.

 

Thanks

Here is output from openocd as provided by espressif:

replacing bin and share in visualgdb folder seems to have worked. Any issues running this way?

 

Thanks

I also get this when I try to use the regular embedded project wizard:

I can’t help but think my install is borked or something..

Sorry for being spammy, I can’t seem to edit my posts. I updated the makefile manually like so:

$(BINARYDIR)/main.o : Src/main.c $(all_make_files) |$(BINARYDIR)
$(CC) $(CFLAGS) -x c++ -c $< -o $@ -MD -MF $(@:.o=.dep)

If someone has a better solution let me know. I know I should be declaring my classes outside of main.c, am a bit of a noob just messing around. Cheers

[dave93cab]

Disabled resharper and that solved the uint32_t issue.

Renaming main.c to main.cpp solved the adding a class issue. Regenerating with stm32cubeMX creates a brand new main.c file though instead of merging with the existing one..
