EmBitz - Using EmBitz

How multi core - Newb questions

Tue, 25 Nov 2025 16:44:15 +0100

I have managed to create new project from scratch for stm32h7, got both of them working. Now i want to setup simultaneous debugging for both cores. Please guide me in setting up the CM4 project to debug and how to do simultaneous debugging?

Mousing Live View?

Fri, 16 May 2025 00:42:37 +0200

Have forgot how to turn on "live view" when mousing over changing variables , how was this done?
Example:
MG6acc1+= MG6fc1; // 32bit up counter
MG6buff1= MG6acc1>>16; //16 top MSB up count stored in MG6buff1

I can see MG6acc1 counter values flying by but nothing in MG6buff1 when mousing over.

EBlink : can't load device-script : stm32auto.script

Tue, 18 Feb 2025 17:16:30 +0100

Hi,
Have installed EMBITZ 2.63(29) and EBLINK 5.30. For test I defined a small program for stm32f407VG disco using the project wizard. I included use of EBMonitor and ebmon.c and .h were added to the project. In the generated main.c  source I added for test of ebmonitor a printf("\f I am alive \n");
As expected the build was ok. However running Debug gives the the message :   "can't load device-script : stm32auto.script".
I've checked the 3 environment vars in windows 11 for EBlink. They are:
EB_SCRIPT_PATH C:\Program Files (x86) \EBLINK\scripts (here it actually resides)
EB_SCRIPT_ PROBE stlink
EB_SCRIPT_SCRIPT auto
which seems allright to me.
I am using STlink   V4.5

I have no clue were goes wrong, Would appreciate your advice.

Stm32F0 series debug problem

Wed, 15 Jan 2025 17:32:33 +0100

Hi,
While debugging an STM32F0 series processor with swd debug, when I place a breakpoint on any line and debug that line, the system resets itself. This does not happen with the STM32F1 series. Why?

Thread safe Newlib Nano heap

Thu, 12 Dec 2024 12:17:58 +0100

Hi!

I'm working on a STM32G473 project using FreeRTOS.
Due to FLASH memory size limitations, I had to change from using Newlib to Newlib Nano-branch, and with this, I lost malloc/free heap thread safety.

With Newlib, I had the heap thread safe by implementing these functions with a FreeRTOS mutex:

void __malloc_lock(struct _reent * ptr);
void __malloc_unlock(struct _reent * ptr);

But these functions are not called from Newlib Nano.

I've googled around about Newlib Nano-branch, and some older versions does not provide this feature, but other versions seems to support it,
for example on this link: https://sourceware.org/git/gitweb.cgi?p=...3d3167e0cb

Any suggestions how I can overcome this?

STM32H7 Dual core

Mon, 25 Nov 2024 19:30:22 +0100

Does someone has a basic template project for STM32H7 with dual core..
Maybe something on Github.

I Suppose there is in fact 2 projects, one F7 and one F4

I'm sure how to handle dual core at this time and debugging it..
honestly I did not try..

Headless build

Thu, 11 Apr 2024 10:43:44 +0200

Hi there,

we are using EmBitz to build some old software with the RealView compiler, where EmBitz is our alternative to µVision4, since EmBitz is so much faster.
We would like to automate the build, but we could not find a way to do a headless build with EmBitz.
Is there a way to use EmBitz headless / via command line?

Thank you very much for you help.

Best regards

Benjamin

CMAKE

Thu, 21 Sep 2023 14:20:33 +0200

I use QT to make PC apps to support my personnal embedded development, and they move to CMAKE, hostnesly i don't like CMAKE, but with QT they handle it like a project file. and create the tree in IDE from it.. Also it search only in file included in the project.

Did you considered using Cmakelist.txt as project, or maybe a converter to Import/Export?

I will like to move the big eclipse project with cmakelist.txt to Embitz.

Thank you.
have a nice day!

Debugging session closes when pressing continue too fast

Tue, 08 Aug 2023 19:14:42 +0200

I sometime encounter an effect when debugging in embitz: when I am stepping from breakpoint to breakpoint and press F5 too fast before the debugger hast stopped I get a message window "GDB debugger Error" with the message "Cannot execute this command while the selected thread is running.". After confirming this message, the debug session stops, ignoring that the error actually would not be fatal. Is there a way to allow to stay in the debug session?

GCC Include as Macro Expansion

Wed, 19 Apr 2023 21:17:51 +0200

HI Gerald,

I want to do macro expansion using gcc inside Embitz.

You have custom tool that are very useful for that, but there is a missing variables that I need to do the job, and it is not known to me and it is not define in the list.

in the command below

GCC -I -I -E file.c

I need the variables to list all include directory for the macro expansion to occur.

Something like ${PROJECT_INCLUDE_DIRECTORY}

Pretty sure it exist!!

Thank you, hope you can help

Cannot open IDE on Chinese OS

Wed, 19 Apr 2023 11:26:26 +0200

Hello,
I installed version 2.5, but it cannot open. It always crashed after search plugins. (All version 2.xx have the same problem)

Version 1.11 can work good.

My OS is windows7 pro.

C++ Compile Problem ( Flatbuffers) and Tensor flow Micro

Fri, 31 Mar 2023 13:41:38 +0200

Hi! I have been trying to compile Tensor flow Lite Micro Arduino Port (https://github.com/tensorflow/tflite-mic...o-examples) on STM32 with EmBitz 2.5.

Adding the folders/files to an empty C++ project for an STM32F4 target as neeed. (TensorFlow and ThirdyParty folders and TensorFlowLite.h) .

The problem comes with the Flatbuffers lib (At ThirdyParty folder) that it's a bunch of .h file with C++ content.

It seems that the ide cannot assing C++ libs for this specifc library. This Tensor flow port is intended to run on CM4 targets on arduino so it should works with Embits???

Can some one help? The hw/firmware part of the for the project it's almost done I only need to build this library with Embitz and I don't want to chance for STMcube

Any one can help please?

Text block selection

Tue, 31 Jan 2023 19:41:26 +0100

Hi,

in version 2.5, the text block selection works different to version 1.11. When I use Shift+Alt+Cursor, I can select a rectangular block of characters. When typing with a block selected, the old behaviour was to add the typed key into every line that is covered by the block. With the version 2.5, typing results in the selection changing to the standard cursor and the typed key is entered only once. Is there a setting that has to be changed to restore the original behaviour?

Newb questions

Tue, 13 Dec 2022 15:10:50 +0100

Greetings,

I'm trying to give Embitz a real thorough try to determine if I want to migrate to it for my projects. I've experimented with it some (STM32) - but I have a few basic newb questions that I couldn't figure out easily.

1) Stupid one: Is there a dark theme? The interface prompts for a file but I don't see one. I enjoy my development to be dark. In Keil I was able to do this for the editor window only - the other window panes were white. ugh.

2) I see there is a workspace - but I'm not really sure how to run multiple copies with multiple hardware debuggers. (I did see the option to allow running multiple copies, but I wasn't sure how the projects and workspaces worked together)

3) I wasn't able to see a way to look at flash memory for debugging. Is this possible?

4) I am starting a project with an STM32H745 MCPU which has 2 cores. Can embitz support dual proc debugging? I'm not sure how configure something like that either.

Thanks for answering my newb questions!
