I want to know why I can't open the file on the STM microcontroller. I get an error that states to install EWARM V8 toolchain to open the project. I already have downloaded the trueSTUDIO and tried to link it but still haven;t open any of the projects

[CGalv.1]

How can I solve this?

Hello @CGalv.1​,

What exactly did the error message? Please share the screenshot of your issue.

Note that TrueSTUDIO is not recommended for New Designs (NRND).

It's recommended to use STM32CubeIDE (an all-in-one multi-OS development tool).
