STM32H7B3I - First Experience with CubeIDE

Jan Cumps

I'm selected for the STM32H7B3I-DK -  DISCOVERY KIT.

I have just set up a clean CubeIDE install, and also installed the resource packages for this kit.

Additional I installed TouchGFX and the standalone Cube Programmer.

Versions:

  • STM32CubeIDE Version: 1.4.1
  • GNU for STM32, 7-2018 -q2 update
  • TouchGFX Designer 4.14.0
  • STMCubeProgrammer  2.5.0

 

The kit has arrived, and the first results have been mostly successful, except for graphic projects using TouchGFX.

What works for me:
image A graphical STemWin project. I imported the example in CubeIDE, built it, loaded via STLink and debugged it.

image Out of Box binary downloaded from product page and then upload it via STLink using the STMCube Programmer.

 

image

 

 

image what I can't get to work yet: Compile a ToughGFX (example import or a self-made project) and load it on the board from CubeIDE.

The compilation / build succeeds. The STLink debug session starts but then the firmware load fails.

 

Error in final launch sequence:

Failed to execute MI command:
load D:\\users\\jancu\\STM32CubeIDE\\workspace_1.4.0\\TouchGFX\\STM32CubeIDE\\TouchGFX-STM32H7B3I-DK_OoB-Release\\TouchGFX.elf

Some investigation to do ...

(solved, see comment below)

  • There must be a config file somewhere in TouchGFX to allow for setting the path to STM32CubeProgrammer and such.

     

    One option would be to set it in the gcc/Makefile for the project:

     

    stm32cubeProgrammer := STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin\\STM32_Programmer_CLI.exe
stm32cubeLoader := STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin\\ExternalLoader\\MX25L512G_STM32F769I-DISCO.stldr

ifneq ("$(shell find "$(PROGRAMFILES)\\$(stm32cubeProgrammer)" 2> nul )","")
# STM32CubeProgrammer is placed in Program Files (x86)
st_stm32cube_programmer := "$(PROGRAMFILES)\\$(stm32cubeProgrammer)"
st_stm32cube_external_loader := "$(PROGRAMFILES)\\$(stm32cubeLoader)"
else
# STM32CubeProgrammer is placed in Program Files
st_stm32cube_programmer := "$(PROGRAMW6432)\\$(stm32cubeProgrammer)"
st_stm32cube_external_loader := "$(PROGRAMW6432)\\$(stm32cubeLoader)"
endi

     

    TouchGFX 4.14.0 just recently came out so perhaps there are some issues with it.  I did not seem to have these issues with 4.13.0 though.

     

    Nice work getting past this though.

     

    The installation page for TouchGFX does have messages concerning the location of the STM32CubeProgrammer. This still should be something that can be set tough.

    I haven't been able to get something on a screen with a fresh project started from CubeIDE yet.

    RTOS runs, but my screen isn't shown - investigating.

     

    What I did get to work, is have the CubeIDE load the TouchGFX example that you can import, and TGFX-generated examples,

    by changing Debug settings, and selecting external loader MX25LM51245G_STM32H7B3I_DISCO, 0x90000000, NOR_FLASH, MX25LM51245G_STM32H7B3I-DISCO.stldr.

    Using the default STM32 Cortex debug settings (that work with a CubeIDE generated project) fails during load.

    But using the external script works.

     

    Action photo below: debugger breaking on clicking the light control ON in the bathroom.

    I still want to fiddle out how to get a CubeIDE generated project working with TGX-Designer. Because I want to use the configurator to manage other hardware.

    That's not working with TGX-Designer and the imported project.

    I think it's a silly thing, but yet to find out ...

    I got the touch screen working too now.

    This is a little complex. I'll write a separate blog about it.

    For the interested and fellow road testers, I attached a project zip to the main article above.

    It works with TouchGFX Designer, CubeIDE,the MX Configurator.and the debugger.

    Nice!

     

    1 Out of curiosity, when you are creating a new project in CubeIDE, are you creating it as a STM32 Project or just a plain C/C++ Project?

     

    2 Also, with TouchGFX, You should be able to create a project from TouchGFX for the board you are designing for, Generate Code from the Interface, and then click "Browse Code" at the bottom right of the screen to get to the generated code.  This takes you to the TouchGFX folder, but if you go up one, there should be a STM32CubeIDE folder with a .cproject file that you can just click on to open the project in CubeIDE.  That seemed to work for me with other boards, although I have not done this with the STM32H7B3i.

     

    3 One issue I did run into with CubeIDE was that after upgrading to 1.3.0 it would no longer create projects using STM32 Project.  I had intially installed CubeIDE in a non default location under a 'H:' drive, so I ended up removing it and then reinstalling CubeIDE and just let it install it in the default location.  This seemed to solve the issue.  It's a bit quirky like that.

    1: I create an STM Project, then select C++. For the TouchGFX ones, I prefer to create one from a .ioc file generated by TouchGFX Designer. Because that has all LCD settings right. (but uses an older firmware version of STM35H7xxxx).

     

    2: yes. But those projects don't work with CubeIDE's HAL configurator (the *.ioc file). And that's a bit of a bummah when you want to use HAL for not-yet-configured peripherals, such as an extra UART (that I need)

    And debug didn't work. But that's an easy fix (ok - I spent 2 days figuring it out, but now it's easy). Select a custom loader in the debug config, instead of the standard debugger you get when starting a first session as STM32 Core XXx type.

     

    3: I have the latest. 1.4.1, with the TouchGFX 4.14. It does not have that issue. It has others, but I found fixes for those. Took me 3 days of debugging though image.

    It's either me missing how to add/enable certain functionalities, or errors in the wizards.

    For the LCD, the CubeIDE wizard (GFX Generator 4.14) doesn't create particular virtual functions in a class that TouchGFX Designer 4.14 does create, and that the runtime needs.

    For the Touch screen, it involved adding HAL drivers by hand, configuring header files and implementing methods that TouchGFX Designer 4.14 implements, when it creates a program, but CubeIDE TouchGFX Generator 4.14 doesn't.

     

    Now that I know it, it should be repeatable. It was a lot of work and step-by-step debugging an RTOS program though. Deep deep into the HAL layer ( will probably pop open a Champaign bottle when he reads this image ).

     

    From here on, things are going to be much easier, I expect.

    Yeah, I tried to create a basic AnimatedImage Example for the STM32H73Bi from TouchGFX 4.13.0 and went through he same process I had done for other boards and it failed to load in the CubeIde.

     

    Failed to execute MI command:
 load C:\\TouchGFXProjects\\STM32H73Bi-Test1\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf  

 Error message from debugger back end:
 Load failed

Failed to execute MI command:
 load C:\\TouchGFXProjects\\STM32H73Bi-Test1\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf

Load

     

     

    I tried to use the STM32CubeProgrammer directly, and it failed as well.  Then I tried to load just one of the STM32H73Bi-DK-Demo examples and that failed as well.  I noticed in the CubeProgrammer that it listed an older FW rev as was updated from CubeIDE so I had it load that as well and reset the config.

     

    CudeIDE FW: V3JM2

    CubeProgrammer FW: V3J5M2 Debug+Mass storage+VCP

     

    After selecting to erase the full chip flash, I was able to load the example and the Out of Box example without issue. 

     

    There is something not right either with the CudeIDE or what is be created from TouchGFX for this board.

     

    One thing I did notice with the TouchGFX (4.13 and 4.14) code gen for this board, after opening the project in CudeIDE, there is a warning listed where it can not find the RTOS folder:

    Invalid project path: Include path not found (C:\TouchGFXProjects\STM32H7B3iTest2\Middlewares\Third_Party\FreeRTOS\Source\CMSIS_RTOS).

     

    Looking on my system, this folder does not exist but a V2 one does:

    C:\TouchGFXProjects\STM32H7B3iTest2\Middlewares\Third_Party\FreeRTOS\Source\CMSIS_RTOS_V2

     

    In the CudeIDE Path and Symbol settings, but folders are listed, so I deleted the missing one.

    Looking at some previous projects, for the STM32F769i I created, the code that was generated did not include a V2 folder. This looks like a bug in the TouchGFX code gen for the H73Bi board.  I'll have to post this at ST.

     

     

    Sorry, didn't mean to hijack your post.

    I have that warning too. The wizard creates an include in the project of a folder that does not exist.
    It can be removed via Project -> Properties -> C/C++ Build -> Settings ->  Tool Settings -> MCU G++ Compiler -> Include Paths. (or in the CudeIDE Path and Symbol settings, as you mention)
    Select "All Configurations" at the top of the dialog before doing that.
    It's a bit sloppy, but harmless.
     
    I'll have to post this at ST.
    I plan to post things I can't get resolved. All others, I am going to put in my road test report as experience. 
    I always hope that the manufacturer follows along with road tests.

    Yeah, I was able to get a project from TouchGFX, built with STM32CubeIDE and loaded using CubeProgrammer without fiddling with anything; outside of down grading the FW to use the CubeProgrammer and doing a full chip erase. There was an error at load time but the code does run. 
     
    I did post the error from the Debug with the CubeIDE and it appears that others are seeing this with other boards.
     
    I have found these vids to be helpful when working with TouchGFX and the CubeIDE.
