Thumb-2 is a superset of the Thumb instruction set. Thumb-2 introduces 32-bit instructions that are intermixed with the 16-bit instructions.

Part Number: TDA4VM-Q1 Hi, In order to optimize the program, I tried to switch the compilation mode from ARM to Thumb-2 for our project.

後來又有Thumb2 的出現，原本單純的16 bits Thumb 指令集加入了一些32 bits 的指令， 也加入了IT (If Then) 指令。 所有Cortex-M CPU都使用Thumb-2指令集. 參考資料. ARM指令

This post explains why the Thumb-2 can be a better option for many applications and also how to configure it in Yocto build system.

There are two instruction sets: ARM and Thumb. They are both 32-bit in the sense that they operate on up-to-32-bit-wide data in 32-bit-wide registers with 32 ...
