Hello @RPari.3​ ,

Let le first welcome you to the STM32 Community :smiling_face_with_smiling_eyes:

Thanks for your feedback. Actually it is a bitt odd that you're encountering such issue.

Could you please precise which version of STM32CubeMX are you using ?

Note that starting with the version 6.2.0, STM32CubeMX embeds the Java Runtime Environment required for its execution and no longer uses the one installed on the machine.

Furthermore, you'll find detailed steps to correctly install the latest STM32CubeMX version in the linked Reference Manual.

Hope this helps you resolve the issue.

Khouloud.

Hi Khouloud OTHMAN,

Thanks for the prompt reply!!

I tried to install STM32CubeMX 6-0-1 and installed java_64_8_45 as suggested by the software itself. I also tried to install a higher version of software STM32CubeMX 6.2.1 but getting the same error with no java installed.

I tried to uninstall the software many times and install it correctly. I have used the software earlier on different machine and it worked perfectly fine for me with same installation process. The machine configuration are almost same as earlier. FYI I am using Windows 10 pro 64 bit OS.

Please let me know if any further information needed.

Thanks

Hi @RPari.3​,

Thanks for the detailed explanation and for having reported. It's strange that you're getting such issue, it may be related to your machine since you're not able to reproduce it on another machine. From my side, I have no problem with installing the tool on a machine with the same configuration as yours.

In this case please retry to uninstall all the STM32CubeMX and JAVA versions in your machine (check "Force the deletion" box) and verify that CubeMX is completely deleted:

If the problem still not resolved, please attach the STM32CubeMX.log file that you'll find under [C:\<User_path>\.stm32cubemx], it may reveal something about the root cause of this misbehavior.

Khouloud.

Hi @RPari.3​,

Thanks for those inputs.

Unfortunately the .log doesn't reveal a big thing except a java exception when trying to load the project. This exception can be due to an invalid configuration in the project you're loading.

Could you please attach your .ioc file to check it from my side.

Thanks in advance,

Khouloud.

Hi @RPari.3​ ,

Actually, I've been able to successfully open the attached project, no error message was displayed:

0693W00000Bawt5QAB.png 

In fact, the "Not a Valid ioc" error can be displayed in case of an empty Mcu.Name or File.Version in the .ioc file.

Otherwise, I tried to start a new project based on STM32F407G-DISC1 board (with initializing all peripherals to their default mode) to mimic your attached project. You'll find attached below the .ioc, please try with it.

Hope this resolve your issue.

Khouloud.
