Every time I try to generate code using the latest version of CubeMX, the software freezes and remains unresponsive for hours. I have tried using previous versions, but the problem persists. How can I resolve this issue?

Screenshot is attached below.

Please help regarding this issue.

Hello again @NajeebUllahKhan 

I would appreciate it if you could tell me the operating system you are using.


I'm using Window 10 (pro) on PC.

What should I do to resolve this issue?

Hi, I installed Java JDK and then tried to Generate Code using CubeMX but still progress bar remains stuck forever. Problem still exist. Kindly help regarding this issue. Waiting for suitable answer.

Hello @NajeebUllahKhan 

The installation of Java JDK will not have an impact as CubeMX installer contain the JDK needed by the tool.
However, to understand the issue I will need you to start CubeMX in command line mode, generate the code and share with me the log.
To do so please open the CMD in the installation folder of CubeMX and use this command to start the tool.

jre\bin\java -jar STM32CubeMX.exe -i
