Hi @Natali 

Hm, lot of unknowns here. Keil switched from AC5 to AC6 (Clang) toolchain lately. Which one are you using in V5.39 and V5.40 ?

I did try to move one of my C++ projects (not using Gfx) from 5.36 to 5.4x and after few weeks I concluded that the latest C++ (17) features I wanted to use are not worth the risk of 'upsetting' working application. Additional complication in my case was Keil's package management and uVisions's automatic handling of CMSIS versions. In parallel, Keil is gradually abandoning uVision and Dev team is focusing on porting MDK to Microsoft VS Code. To me, it is a complete, rather scary jungle.

What is your motivation to move to v5.4x ? Do you really need to change to the latest toolchain/MDK (c++17 features) ? I would stick with what works and wait (few years) till 5.4x is well tested.

Try Keil's forum or support, they are very responsive and helpful.

They've been using the version 6 compiler for a while.

It's probably an issue with CMSIS, I was fighting with their Packs the other day on a system that had been using 5.38a without issues.
