= Issues =

* If "st-info" shows no device, then check if the usb wine is good
* Stm32CubeIde does not work with none-original ST-Link device, error:
[[Image:stm32cubeide-error.png|600px]]
* If install old version of stm32cubeide, "“STM32CubeIDE is damaged and can’t be opened" <ref>https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-is-damaged-and-can-t-be-opened/td-p/256814</ref>
