STM32CubeMX project open bug : I can't open my project file since the last update.

[Sebastien1]

Hello,

Since the last update of STM32CubeMX 4.26.1, I can't open my project file anymore.

Right after clicking on the 'open' button, the software freezes and one of the processor cores stays at 100%. The only available action, then, is to close the application.

As I can't download an older version of STM32CubeMX, I am out of options.

I attached the project file in question to this post.

Thanks in advance for your help.

Running

java -jar "c:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\STM32CubeMX.exe"

from the commandline might give some hints.

Yes, effectively !!

But how I can resolve the problem ?

I have a NullPointerException in "com.st.microxplorer.mcu.IP.getOnlyRefParameters(IP.java:1236)"

Thanks !

I found the bug !!!

Here the steps to produce it :

1. Start the STM32CubeMx software with the following command (to able to show the output debug)

java -jar "c:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\STM32CubeMX.exe"

1.  
2. Click on "New Project".
3. Write in "Part Number Search" : STM32F207VC
4. Double click on the only part available.
5. As soon as you are in "PinOut" tabulation, uncollapse "ADC1".
6. Activate "IN0".

The bug appear.

Thanks in advance for resolve the bug.

Can you give the possibility to the user of the software to download the previous version ?

Because, since 2 weeks, I am stuck, and now I need to wait additionnal 2 weeks.

My boss don't understand this situation.

Currently, when a new version of STM32CubeMX come, the software download and install the new version.

But, if the new version have a bug, it is impossible to roll back to the previous version. It is also impossible to download anywhere the previous version. Why ?

The simple way is give the possibility to download the previous version of the software like this :

Current version :

CubeMX release 4.27.0

Previous version :

CubeMX release 4.26.1

With this solution, a user can continue to work before a solution can be found by your team.

I am having the same issue with CubeMX 5.2.0: when I am trying to open a project saved with earlier version of CubeMX it freezes.

​Hi @Community member​ @Community member​ ,

can you tell me the old project is created by any version of CubeMX?

Also which MCU family your are using (H7, F4, ...)?

Thanks,

Houda

The project was created using CubeMX 4.27.0. The MCU is STM32L475RCT.

I eventually found a solution after posting yesterday.

I downloaded intermediate version 5.1.0, which was able to open the project, then saved project in that version of CubeMX.

Then, version 5.2.0 was finally able to open the re-saved project.
