Starting with the STM32N6570-DK
I'm not exactly sure how to optimally use this board or even setup a basic program, flash it and run it. I have experience with Tiva C with Code Composer (I imagine you're forced to use this program in purgatory) and Keil (not horrendous, but definitely not good or user friendly), but I have seen comments here mention that STM is transitioning to the VS Code Extension Pack (where following a few YouTube tuts get me a deviceName attribute not set error upon debugging). I've also seen comments mention that CubeIDE is feature rich for beginners in the STM space.
Finally, trustzone, secure, not secure, FSBL, Appli(non)Secure. I'm confused on the intended purpose or usefulness of the terms or where my program/code should lay. I'm starting to regret getting the apparent "best" MCU just because I could afford it for my personal project.
