Question

toolchain installation failures

Hi.  I have a newly purchased NUCLEO-U575ZI-Q.  I followed the instructions here to install the toolchain on Windows 11:

https://www.st.com/en/evaluation-tools/nucleo-u575zi-q.html#documentation

https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step1_Tools_installation

After one unsuccessful attempt where I chose my own installation folders, I uninstalled everything and took the defaults.

What a mess!  The default installation folders are spread between AppData, Program Files, and C:\ST.  But OK, if that's what it takes.

Unfortunately, I got to step 5 and found that the instructions diverge from reality.

They never said to click Finish to complete the Import Projects dialog.  And there is no way to select the project they mention from it.  But if I click Finish, then a tiny icon appears on the upper left.  If I click it, then there is a Project Explorer window.

The next step is:

My IDE has no Debug icon (the the little yellow blob on its lower left).  But it does have a Debug As icon.  Clicking that one results in:

So now I'm stuck.

Any help would be greatly appreciated!

Thanks,

Mike

    "The selection cannot be launched..." refers to the selection in the Project Explorer View. Make sure that the project icon of the project you want to debug is selected. 

    UM2609 STM32CubeIDE user guide may also be helpful.

    The project was indeed selected.

    So it seems that was not the issue.

    Hi,

    this is not an Arduino: click on anything and it works somehow. :)

    1. load/install IDE 1.19.  (yes..ok...etc. , as it wants.)

    2. start new stm32 project...select your chip U575 or board nuc..-575... give name etc...see chip pin layout.

    3. then do/create what you want, set clock tree to something useful, click generate code...and compile/debug...

    You will have to learn a lot, but in the end you can create, what you imagine ..within the limits of selected chip.

    Hello AScha.3,

    I'm not trying to create a new project from scratch.

    I'm trying to run one of the predefined examples (I'm following the official tools installation steps here:  https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step1_Tools_installation).

    Even though it's not an Arduino, is it too much to expect that one of the provided examples for the NUCLEO-U575ZI-Q should come ready to compile?

    It's a serious question.

    As the installation steps suggest, I got the example from STM32CubeMX:

    mdeis_1-1765467516508.png

    mdeis_2-1765467543049.png

    All the examples then showed up here:

     

    mdeis_4-1765467664587.png

    The tools installation steps suggest that one should be able to simply click "Debug" and run the example on the device (assuming driver installation succeeded).

    Should I not expect the installation documentation to be true?

    Thanks.

    Mike

    Hi,

    BTW, the instructions say:

    mdeis_0-1765469457741.png

    But on my board, the CN2 header is not populated:

    mdeis_1-1765469549073.png

    And there are four leads!  What should be jumpered to what?

    The board documentation (um2861) makes no mention of it.

    Thanks.

    right, see circuit of board:

    its for programming the st-linl itself - you should never need it.
