How to fix STM32CubeMX Code generation failing for Keil uVision since STM32CubeMX version >5.3?

[TBrow.3]

Code generation is failing when using STM32CubeMX 6.1.0 with a Keil uVision project. 

 

Code generation for a uVision project is working for STM32CubeMX Version 5.3.0, with any uVision version. After STM32CubeMX Version 5.3.0 code generation fails. The log file looks like it can't find the generator:

 

My sytem:

Windows 10 Pro (Ver. 20H2, Build 19042.572)

Keil uVision V5.29.0.0

STM32CubeMX Version 6.1.0

I have tried reinstalling different versions of uVision and STM32CubeMX.

I have tried changing Java versions.

Any ideas? I would really like to use some of the features in the newer version.

Hello TBrow.3,

Can you please indicate what version of Java are you using ?

It will be more helpful that you attach the .log file in order to detect the problem.

Hi Khouloud,

I've attached the log file from STM32CubeMX version 6.1.0

I was originally using this Java version: jre1.8.0_271

After seeing someone else solve their issue using openJDK I switched to this:

openjdk version "11.0.9" 2020-10-20

OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9+11)

OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9+11, mixed mode)

Regards,

Tal.

Hi TBrow.3,

Backing to your .log file you are using Java Version 13.0.1:

 

In fact The use of Java Runtime Environment (JRE) 64-bits is mandatory. JRE 32-bits is no more supported. The JRE minimal version is 1.8_45. The version 1.8_251 must not be used (known Java™ issue). Java™ 11 is supported. Java™ 7, Java™ 9, Java™ 10, Java™ 12 and upper are not supported.

For more details about CubeMX software requirements, please refer to the User Manual.

Uninstalling Java in your machine and installing a supported version will absolutely resolve your issue.

Regards,

Khouloud.

Thanks. Now using Java 11, all working. Got to read the fine print.
