Hi all,
Sorry for late response, but we managed to find solution. Java for STM32CubeIDE should be changed to enable Yakindu.
For Linux and IDE 1.9.0, AdoptJDK 16.0.2 is ok.
Just change -vm parameter to point to new Java in stm32cubeide.ini of IDE instalation directory:
-vm
/home/user/opt/java/jdk-16.0.2+7/bin
Off course, your path is probably different.
